Answering Your Questions About PRISM Live Studio

Starting on May 1, 2024, Apple mandated a Privacy Manifest for all apps registering on the App Store. This specification focuses on user privacy by detailing the reasons for data collection by both the app itself and any third-party SDKs it utilizes.

The Facebook SDK used by the PRISM app also had to adhere to this Privacy Manifest specification. As a result, PRISM app may display Facebook App Tracking Transparency Permission Request.

This is also known as App Tracking Transparency (ATT), which is aimed at protecting user privacy. Depending on the user’s operating system version, the PRISM iOS app can request permissions within the app with the following guidance:

PRISM app may request permissions with the following guidance within the app based on the user’s OS version. If you see these guides, please carefully review each of them to grant permissions so that PRISM app can start streaming to Facebook properly.

Due to insufficient storage space, you might want the option to not save videos during live streaming in the PRISM iOS app. And it could also offer performance benefits. Not saving videos during live streaming reduces the strain on device resources that would otherwise be used for video storage, potentially causing device overheating and performance degradation.

You can use the Temporary storage of live streaming video files option in the Settings page to stream live video without saving it. If you don’t need to retain the recorded video after the live broadcast, utilize this feature to conduct live streaming in a better device condition.

Mobile, Guides, Streaming, Configuration

Both landscape and portrait screen orientations are supported on the PRISM mobile app. However, we have received several inquiries, such as: “Why is the broadcast locked in portrait mode even though I began streaming with my phone in landscape?” or “Why am I unable to rotate the screen orientation during a broadcast?”

If your phone is positioned horizontally but the broadcast still displays in portrait mode, this issue is likely due to the screen orientation being locked in your phone settings. Many users often have their phone's screen orientation locked in portrait mode. As a result, even when holding the phone horizontally, the locked orientation prevents the screen from adjusting correctly.

Additionally, if you rotate your phone in the opposite direction from the selected orientation after starting a broadcast, a notification will appear on the screen. This notification indicates that the screen orientation has changed from the preset configuration. Please note that the screen orientation cannot be adjusted once a broadcast has started.

If the YouTube channel has more than 50 subscribers, the feature to resume your previous live streaming to YouTube is supported. Resuming a live stream means starting a new live stream using the same link as the live stream that viewers are currently participating in.​

When you try to end your live stream, a dialog will appear asking whether to keep the YouTube live session active. To keep the current live session active after ending the stream, click the “Keep Session” button.

And then, when you enter the live preparation screen, a pop-up will appear for the active live session. After reviewing the details, tap the ‘Check

GIPHY offers a vast library of GIFs through its partnership with the PRISM app, making all GIFs on giphy.com available for use. To access GIPHY effects in PRISM, click the effect icon () next to the Go Live button, then select the GIPHY effect icon (), as shown in the image below.

Once you access the menu, you’ll find categories like Trending, Reactions, and Thanks, along with a search function to find specific effects.

The PRISM app provides two chat modes. One is the basic chat area, available by default on the live preview screen, and the other is the PRISM chat widget area, accessible through the widget menu in My Studio.

You can enable the automatic disappearance feature for chat messages in the PRISM chat widget area. To use this function, check the Disappearing Chat Messages option. With this feature, older chat messages can automatically disappear.

The disappearance interval offers various options, such as 5 seconds, 15 seconds, 1 minute, or 2 minutes. Feel free to give it a try.

Nowadays a lot of PRISM users are streaming to Kick.com using the Custom RTMP feature.

Unfortunately, we are not yet able to support platform login based integration into Kick.com. For that we need their public API as it is not yet supported.

But we’re working on improving this, so expect good news soon. And we made a guide for you to use Custom RTMP function in PRISM mobile app.

A comprehensive guide on using custom RTMP instead of platform logins

Today many people are streaming to YouTube. Accordingly, we made videos that walk you through how to start streaming to YouTube from the PRISM app. This is a two video part series, where the first part talks about what needs to be prepared before live streaming and the second part is about actually going live on Youtube.

Streaming to YouTube with the PRISM Mobile App. (Part 1)

SuperChat is a paid system that can support streamers during live streaming. If a viewer sends a SuperChat to the streamer, the corresponding SuperChat will be exposed in the chatting area and a separate widget of SuperChat itself will also be available at the top of the chatting area. Depending on the amount you sponsor, the exposure time of the widget may differ. The remaining exposure time is displayed in a gauge format on the widget.

The PRISM Chat Widget also displays superchats in the chat area, but they are not pinned at the top.

At times, you may need to answer a phone call or open another app during a broadcast, or perhaps you accidentally pressed a button to open another app. The PRISM app can continue broadcasting live even when running in the background.

For Android devices, you need to toggle a setting to activate the background broadcasting feature, as shown in the image below. Simply go to Settings, then enable the following option: Allow display over other apps. This will allow the live broadcast to continue uninterrupted in the background while you use other apps on your device.

The YouTube platform supports a resume feature for live streaming. In other words, even in situations where live streaming ends on a streaming device such as a smartphone, the live can remain in OnAir status on YouTube.

This feature is usually used to keep the link of a live stream alive for a long time. Viewers no longer need to obtain a link to a new live stream from the streamer or platform.

You can keep your live on OnAir by clicking KEEP in the second of the two-step dialogs of the PRISM app.

If there is an OnAir live stream remaining on your channel, the PRISM app provides a slightly different dialog like the image below.

You can resume the stream by selecting it, or you can stop the stream completely using the End the live session button.

Emotion effects are motion effects that allow you to express sudden feelings or situations. To access emotion effects in PRISM, tap the effects icon () next to the Go Live button, and then select the emotion effects icon (), as shown in the image below.

You can tap on each effect to apply it. Some effects support face detection, which tracks your face in real time and positions the effect accordingly on the screen. Face-detecting effects are marked with a small face icon () on their thumbnails for easy identification.

To add an effect to your favorites, simply long-press the effect. You can access your favorites by selecting the Favorites tab () located on the left side of the tab bar. In the Favorites tab, effects are displayed in order of most recent use, with favorited effects appearing first. To remove a favorited effect, long-press it again.

There are eight emotion categories: Greet, Love, Congrats, Awesome, Fun, OMG, Angry, and Sad. Additionally, there are two special categories: RandomTouch and Shopping.

RandomTouch effects appear in random positions and sizes each time you tap on them, adding a playful and dynamic element to your broadcast.

The screen ratios of mobile phones vary, which can cause mismatches between the streamer’s view and what viewers see on their devices. For example, areas visible to the streamer may not appear on a viewer’s screen, and vice versa.

To address this, PRISM offers a Screen Full/Fit option to adjust the display area.

Tap the More button in the upper-left corner of the screen. The default View Screen Full setting displays the broadcast in full screen. If your phone’s screen ratio is slimmer than 16:9 in landscape mode, viewers may see parts of the screen that are hidden from the streamer.

Switch to View Screen Fit to adapt the broadcast to a 16:9 ratio, ensuring it fits entirely within the viewer’s screen. In this mode, black bars (LetterBox) may appear on the sides if the screen ratio is slimmer than 16:9. This allows the streamer to see all areas visible to viewers.

The same principles apply for portrait mode. Toggle between modes as needed to provide the best viewing experience.

ABP (Adaptive Bitrate Publish) is a feature that automatically adjusts video quality based on network conditions. For example, as shown in the image below, the video quality is set to Adaptive by default. This ensures that broadcasts are delivered in the most optimal quality according to the current network conditions.

There are four factors that determine video quality: resolution, bitrate, frame rate, and keyframe interval. You can adjust the details of these options in the settings.

Resolution is the dimension of the video in pixels (width × height). As PRISM supports various resolutions such as 360p, 720p, and 1080p, simply select the resolution of your choice.

Bitrate is a unit that determines how much data should be used per second. Generally, we recommend setting the bitrate to 4000kbps when the resolution is 720p, and 6000kbps when the resolution is 1080p for the highest video streaming quality.

Frame rate refers to the number of frames displayed per second, typically 30fps or 60fps.

Keyframe interval defines how frequently keyframes are inserted in the video stream, typically set to every 2 seconds for optimal streaming performance.

But if you are a rookie streamer, we recommend keeping your ABP on.

You can also adjust the maximum bitrate when adaptive bitrate is enabled. If the network is stable enough to support the set bitrate, the stream will maintain that quality. However, if the network conditions degrade, the video quality will automatically adjust.

The heat generated by smartphones performing live streaming also affected the stability and quality of live streaming. Live streaming running on a smartphone is an operation that uses a lot of the device’s resources, so if you use the function for a long time, the heat will inevitably increase.

​We also provided guidance on how to improve this situation in the following page:

• Improving Smartphone Overheating for Better Streaming

But also, The PRISM app offers Thermal Protection Mode. The PRISM app checks the smartphone’s thermal status in real time, and when it reaches a bad enough situation that can affect the live streaming quality, the Overheating Protection Setting alert is shown so that the streamer can maintain the live streaming stably.

The alert will guide you to select the options you want, including adjusting the resolution and fps and removing effects, filters and media sources to relieve heat.

YouTube live platform supports receiving H.265 (HEVC) encoded streams, allowing for higher-quality video with the same data usage when streaming to YouTube.

H.265 (HEVC) encoding is automatically applied only for single streaming to YouTube.

The following images illustrate the quality differences between H.264 and H.265 (HEVC) encoding. By enlarging the images to their original size, you can make detailed comparisons, such as examining the patterns in the couch fabric.

You can find more detailed information about the H.265 (HEVC) encoding standard at the link below.

The web browser widget allows you to load a website as a source to your broadcast screen. This means you can now display not only the webpage itself, but also sponsored contents and chat windows to your broadcast.

Please do understand that as there are numerous devices and OS versions available on the market, which means that the maximum number of web sources has been limited to 4 items, in order to ensure that apps can run and broadcast reliably on as many devices as possible.

In the future, as network conditions improve and devices evolve, we will work on improving the availability of even more web sources.

If you are attempting a live stream on YouTube for the first time, you must first create a channel. Additionally, YouTube requires the channel to undergo an authentication process to verify the real user who will be performing the live stream. The live streaming feature becomes available only after completing this verification process.

Since live streaming carries inherent risks due to its real-time nature, this verification can be seen as YouTube's effort to ensure a more secure experience.

For this reason, if the PRISM app detects that your account information is invalid, it will display a message prompting you to visit the YouTube Live Control Room.

On a desktop, you can access the YouTube Live Control Room by logging into YouTube, clicking the CREATE button at the top right, selecting Go live, and entering the Live Control Room.

If your channel has not yet been verified, accessing the Live Control Room will automatically redirect you to the verification page. Follow the instructions on the page to complete the process. Please note that a single phone number can only be used for verification twice a year through an automated voice message or text message.

Once verification is successfully completed via voice or text, you will see a confirmation screen indicating the process is done. However, you cannot start live streaming immediately. YouTube requires up to 24 hours to activate live streaming on your channel.

After the waiting period, revisit the Live Control Room, where you will see confirmation that live streaming is now enabled.

You are now ready to return to the PRISM app and start your live stream.

This guide explains the cause of the current error that occurred during your live streaming.

The PRISM mobile app includes a streaming module that handles RTMP transmission. This module streams your video data to live platforms such as Facebook, YouTube, Twitch, and Instagram.

To do this, the RTMP streaming module in the PRISM mobile app establishes a connection with the RTMP receiving module of the live platform and begins transmitting data. The current error means that while the connection was successfully established, the transmission of data packets has failed.

Known causes that can lead to this situation are as follows. Please review each cause and take any applicable actions. We hope this helps you.​

1. Expiration of Facebook Stream Key

The Stream Key obtained from Facebook’s Live Dashboard for Custom RTMP streaming expires once the stream has been published. Even if the stream hasn’t been published, the key will also expire if the streaming session from your app has been running and the preview remains visible on Facebook’s Live Dashboard for more than four hours.

If you attempt to start a live stream using an expired Facebook Stream Key, the same error will occur. To prevent this, you can obtain a newly generated Stream Key from Facebook’s Live Dashboard. Alternatively, you can enable the [Persistent Stream Key] option there to use a single Stream Key continuously.

2. Data packet reception is blocked on the live platform for your account's RTMP address

Live platforms may impose usage restrictions on their users. For example, if a user starts live streams too frequently on YouTube, the platform may temporarily block the ability to start new streams. This also means that RTMP data transmission can be blocked. If you’ve encountered this error, please check whether there are any restrictions in place on your target live platform.​

3. There is an issue with your network bandwidth

A connection between the app and the live platform for RTMP streaming can be established using only a small amount of data. However, video data itself is usually quite large. So, even if the RTMP connection is successful, the actual video data packets may not be transmitted properly. Please check if there are any issues with your network bandwidth.

4. There is an issue with your network environment

RTMP streaming uses the TCP protocol to transmit data, typically over a specific port—most commonly port 1935, though this may vary. If you are in a location where a network firewall is blocking that port, data packet transmission will fail, leading to the current error. Please check your network environment for any such restrictions.

5. There is an issue with your device

The data packets sent via RTMP streaming are created using the encoder on your smartphone. If there is an issue with the encoder or your device is in an unstable state, it may not be able to produce proper data packets. If you suspect this is the case, please try rebooting your device and starting the live stream again. If you have another device available, try streaming from that one instead.

You can access the beauty effects feature by clicking the face icon next to the Ready button.

RTMP (Real-Time Messaging Protocol) is a protocol used to transmit video, audio, and data from the PRISM app to streaming platform servers, requiring both a stream URL and a stream key.

The PRISM app support a login-based method for Facebook. However, You may rarely experience login issues within PRISM app with various reasons. Most login failures are resolved within a few hours, you might want to connect temporary while than.

A significant number of options offered by the platforms are integrated into the PRISM app. Please make use of the PRISM app for more detailed live streaming settings.

Detailed options for YouTube

You can schedule live streams and configure various options provided by the YouTube platform, including category setting, enable DVR setting, stream latency setting, license setting, and more.

The RTMP Overlay feature allows receiving video from devices capable of RTMP streaming and integrating it as a single source for live streaming in the PRISM app.

You can use the RTMP Overlay function in the Widget menu of My Studio that appears when you swipe left on the Live Ready screen. Select ‘RTMP Video Source’ from the function list of the Widget menu, it will be added to the My Studio source list. And when you click on the RTMP Overlay source in the source list, it will be placed on the live streaming screen.

Once it is placed, it can be resized, repositioned and rotated just like an image overlay. And as soon as that source is placed, the RTMP information that can be streamed to the RTMP Overlay is displayed.

The RTMP information is generated by the combination of the RTMP Stream URL and RTMP Stream Key. Please note that excessively minimizing the RTMP Overlay area may hide the RTMP information.

There may be times during a live broadcast when you need to turn off your microphone or camera.

To toggle the microphone or camera during a broadcast, tap the More button in the upper left corner of the screen. By default, both the microphone and camera are set to On.

As the weather gets hotter, the temperature of the smartphone performing live streaming also rises.

And when the temperature of the phone rises like this, the performance of each module in the device, such as the CPU, GPU, and network module, decreases overall, which lowers the quality of your live streaming.

That’s why we’ll guide you through 9 ways to reduce the heat of live streaming, which especially requires the full power of your smartphone, to make your live streaming more stable.

Removal of the battery charger

Charging the battery is one of the factors that increase the heat of the phone the most, so please fully charge the battery in advance and start live streaming with the charger disconnected.

We are informing you about situations where live streaming fails to start due to video encoding failure.

To stream video to a live platform, the video recorded on a smartphone must be encoded into a specific video format. The encoded video data is then streamed to the live platform, which receives and plays it in a video player that viewers can watch.

However, the PRISM app was unable to generate the video data properly on your device. In such cases, the PRISM app displays the following error screen to the streamer.

We will inform you about situations where the RTMP connection for streaming fails or the live platform does not receive RTMP data.

The PRISM app captures video from the smartphone camera, encodes it into video data, and streams it to the live platform using the RTMP protocol.

The process of transmitting video to the live platform via the RTMP protocol begins with a connection between the PRISM app's RTMP streaming engine and the live platform's RTMP data receiving server.

This error occurs when the PRISM app's RTMP streaming engine fails to establish a connection with the RTMP data receiving server.

We’re informing you that, due to an error on Facebook, live streaming couldn’t start as intended.

Facebook is currently responding with an error called ApiUnknown for the functionality API it provides to the PRISM app. This error occurs when users attempt to start streaming to Facebook groups from the PRISM app.

Recently, Facebook announced plans to restrict group streaming from third-party apps through the following notice. In accordance with this plan, substantial streaming limitations have been implemented starting from April 24, 2024.

This guide explains the cause of the current error that occurred during your live streaming.

​

To stream to Facebook, the PRISM app relies on features provided by Facebook. These features are called Facebook Open APIs, and they are used by third-party apps like PRISM.​

If these Facebook Open APIs are not functioning properly, the PRISM app will also be unable to stream to Facebook correctly.​

We will inform you about situations where live streaming using the ScreenCast function in the PRISM app does not start properly.

This guide explains the cause of the current error that occurred during your live streaming.

You attempted to start a live stream by selecting a scheduled broadcast registered in your YouTube Live Dashboard. However, the stream failed to start properly. This is likely because the scheduled broadcast has either been deleted or is no longer valid.

We’ll walk you through a situation where you tried to start a live stream to Facebook, but it couldn’t start due to an error Facebook responded with.

The current error occurs when your Facebook posting rights, including live streaming posting rights, are temporarily blocked due to a policy violation, or your posting rights to the Page have not been fully approved.

The PRISM app offers Camera Pro mode for users who want advanced control over their camera settings, enabling them to adjust professional features for a more customized live streaming experience. Camera Pro mode supports five features:

• Exposure

• Manual focus

• ISO

• White balance

• Shutter speed

You can find the Camera Pro function by clicking the More-button located at the top left.

Exposure

The Exposure feature lets you control the brightness of your video with precision. By adjusting the exposure slider, you can brighten or darken your shots to suit different lighting conditions.

Manual focus

The Manual Focus feature allows users to have precise control over the camera's focus point. By simply sliding the focus adjustment bar, you can fine-tune the focus to highlight your subject exactly as desired.

You can toggle the Auto / Manual button on the right side to switch between Auto Focus and Manual Focus modes. However, this can also be done conveniently without accessing Camera Pro mode. For more details, please refer to the page below:

ISO

The ISO feature allows you to adjust the camera's sensitivity to light, giving you greater control over brightness and noise levels in your video. By increasing the ISO, you can capture clear footage in low-light conditions, while lowering it helps maintain image quality in bright environments.

You can toggle the Auto / Manual button on the right side to switch between automatic and manual ISO modes. In Auto ISO mode, the ISO value is prefixed with an 'A' (e.g., A3264), while in Manual ISO mode, it appears as a numeric value (e.g., 3264). The Auto/Manual setting for ISO is shared with the Shutter Speed, ensuring seamless control over exposure.

White Balance

The White Balance feature lets you adjust the color temperature of your video to match different lighting conditions. You can manually set the white balance for warmer or cooler tones, or use Auto White Balance mode to let the app automatically optimize the colors. This feature helps ensure natural and accurate color representation during live streaming or recording.

You can toggle the Auto / Manual button on the right side to switch between automatic and manual White Balance modes.

Shutter speed

The Shutter Speed feature allows you to control how long the camera's sensor is exposed to light. A faster shutter speed reduces motion blur, ideal for capturing fast-moving subjects, while a slower shutter speed lets in more light, perfect for low-light conditions.

You can toggle the Auto / Manual button on the right side to switch between automatic and manual shutter speed modes. In auto shutter speed mode, the shutter speed value is prefixed with an 'A' (e.g., A1/45), while in Manual shutter speed mode, it appears as a numeric fraction (e.g., 1/45). The Auto/Manual setting for shutter speed is shared with the ISO, ensuring seamless control over exposure.

This post explains the causes of situations where you attempt to play, use, or edit a video file in the PRISM app, but the app fails to load the file properly. It also provides guidance on how to resolve the issue.

1. Background of Errors

Video files prepared in either of the following ways may encounter issues during the loading process:

• Video files created by recording or editing within the PRISM app.

• Video files obtained from external sources, regardless of the PRISM app.

Users can create and save video files using the PRISM app’s live streaming, video recording, and video editing functions.

However, there are cases where videos created within the PRISM app cannot be loaded back into the app. Additionally, videos downloaded from the internet or created using other apps on the device may also fail to load properly in the PRISM app.

2. Causes of Errors

This loading issue can occur due to various reasons, including:

• Files created in an incorrect format that does not comply with encoding standards (this accounts for the majority of errors, as videos are created in many different ways).

• Videos that are valid but cannot be processed by the device’s decoder.

• Insufficient memory on the smartphone.

• Failure to generate video thumbnails.

Although we’ve listed seven possible causes, there are many more that we may not have identified. Each issue can be further categorized into different sub-causes, making it challenging to pinpoint and resolve every problem.

Furthermore, replicating the exact conditions that lead to an error is often difficult, as many issues arise from specific interactions between a video file and the smartphone’s decoder.

Over time, we have analyzed and addressed various media loading failures. However, there are still errors we have not yet been able to fix. We sincerely apologize for any inconvenience and will continue working to resolve these issues.

3. How to Resolve Errors

If you experience this issue, you can try the following solutions:

(1) Restart your smartphone

Your device’s decoder may be in use by another app or experiencing an unknown error. Completely power off your smartphone, turn it back on, launch the PRISM app, and then try recording or reloading the video file again.

(2) Re-encode the video

As mentioned earlier, many files are created in formats that do not comply with encoding standards. However, re-encoding the file may allow it to load properly in the PRISM app.

Try opening the video using the default gallery app on your smartphone, making minor edits, and saving it again. Minor changes could include trimming the playback time or adjusting the color tone. During this process, the video is re-encoded and saved as a new file.

If the video does not load even in your smartphone’s default gallery app, this likely indicates a major issue with the file itself.

The PRISM mobile app provide the ability to set the focus manually or automatically through the Camera Pro menu, which can be accessed by clicking the round More button in the upper left corner of the app screen.

But you can easily switch between Auto Focus and Manual Focus without entering the Camera Pro menu, by Focus Mode setting function in the More menu list.

The page below provides a simpler way to change focus without accessing the More menu.

Default focus mode

If you do not touch the screen after launching the PRISM mobile app, the PRISM app is in Auto Focus mode. The camera automatically focuses on the preview image provided through the lens.

Focus changes when screen tap

The way focus changes when you tap the screen depends on the current focus mode.

case 1: Screen tap in Auto Focus mode If you tap the app screen in Auto Focus mode, the app automatically focuses once and stays in Auto Focus mode. At this point, a white focus indicator with a picture of an open lock (meaning Auto Focus mode) is shown where you have touched it.

​

case 2: Screen tap in Manual Focus mode If you tap the app screen in Manual Focus mode, the app focuses once around the touched location and stays in Manual Focus mode. At this point, a yellow focus indicator with a picture of an closed lock (meaning Manual Focus mode) is shown you have touched it.

Focus changes when long press

The way focus changes when you long press the screen also depends on the current focus mode.

case 1: Long press in Auto Focus mode If you long press the screen while in Auto Focus mode, the focus indicator turns white with an animation of the lock closing, and it switches to Manual Focus mode.

case 2: Long press in Manual Focus mode And if you long press the screen while in Manual Focus mode, the focus indicator turns yellow with an animation of the lock opening, and it switches to Auto Focus mode.

​During live streaming on the PRISM app, your live broadcast may be terminated on the target live platform.

The reasons are so diverse that it is difficult to list them all, but some representative examples are as follows:

• A case where your broadcast was stopped on the live platform because streaming was not stable for a certain period of time due to an issue in the network.

• A case where your broadcast was stopped on the live platform due to community violation or report.

• A case exceeding the maximum streaming time limited by the live platform.

While streaming from the PRISM app to the live platform, the PRISM app checks in real time whether your live stream is stable or not on the live platform. And when the app discover that the live stream is not on Air, it will inform you via a dialog as shown in the image above.

If you see a notification like this, please check the status of the live stream on a separate device. And If your live stream was actually stopped, click the OK button to close the dialog and then use the End button at the top right of the app to end the streaming.

Please note that we will continue to add features within the PRISM app that will inform streamers of the live broadcast status on the live platform they are streaming on.

We will inform you about a situation where the live broadcast you are streaming is terminated on the target live platform and the changes in the PRISM app after that.

Live broadcasts streamed through various streaming apps, including the PRISM app, may be terminated by live platforms for various reasons.

The PRISM app checks in real-time whether your live stream is still on air on the live platform while your stream continues.

We are providing information about situations where streaming cannot proceed due to insufficient network bandwidth or an incorrect RTMP address.

This error occurs when the connection between the PRISM app’s RTMP streaming engine and the live platform’s RTMP receiving server is lost for more than 10 minutes.

This issue can be categorized into two cases:

We’d like to inform you about an issue where live streaming couldn’t start because YouTube Stream creation failed.

You need a YouTube Stream to live stream on YouTube.

For users with a YouTube channel that has more than 50 subscribers, the PRISM app is designed to create Streams using the features YouTube provides to third-party apps like PRISM.

However, the PRISM app is currently unable to create a Stream due to restrictions placed on your channel by YouTube.

We will inform you about situations where the live broadcast you are streaming is terminated by the target live platform and the streaming in the PRISM app is also stopped.

Live broadcasts that are actually being streamed can be terminated by the live platform for various reasons. Therefore, the PRISM app checks in real time whether the current live broadcast is being maintained normally on the target live platform while the streamer’s live streaming is in progress.

When it is clearly confirmed that the current live stream is no longer in the OnAir state, such as when the streamer’s live broadcast is terminated, the following information is displayed on the app screen, and streaming in the PRISM app is also automatically stopped.

This process is to prevent a situation where the streamer continues to live stream unknowingly, even though the live broadcast has obviously ended on the live platform.

The main reasons why streamers’ live broadcasts are forcibly terminated on individual live platforms are as follows:

1. In case the streaming processing on the device was not normal

2. In case the live broadcast is terminated according to the community policy of the live platform

3. In case the live broadcast is terminated according to the maximum streaming time limit of the live platform

1. In case the streaming processing on the device was not normal

This case can be further divided into two situations.

(1) A case where the network bandwidth currently used by the smartphone device is insufficient

Smartphones use wireless networks such as WiFi or mobile data networks, which may not be reliable by their nature.

Due to persistently low or temporarily low bandwidth, it may not be possible to stream live video created by the device to the target live platform.

Live platforms also have a policy to forcibly terminate the live broadcast if they do not receive a live video fragment from the device for a certain period of time.

Live platforms have different criteria for the maximum time they will wait to receive video again, and this criterion can change at any time. Please understand that it is difficult for us to provide specific guidance on this matter.

It is difficult to maintain stable live broadcasting if the network bandwidth you are using is insufficient. Please refer to the following guide to secure a more stable and sufficient network:

(2) A case where the smartphone device cannot produce streaming video normally due to heat, etc.

In fact, live streaming is a rather heavy task for a smartphone, as it has to handle multiple tasks simultaneously, such as receiving video from the camera, encoding the video, and sending data to a live platform.

When live streaming lasts a long time, various parts of the smartphone device become hot. Heat builds up in areas such as the camera, screen, CPU, and modem, which can eventually lead to a deterioration in video quality and device functionality.

In severe cases, the device may not be able to produce the amount of video it should within the set timeframe. In this case, the live platform may not receive the video normally, and the live broadcast may be terminated, just as in the case of network issues we introduced earlier.

If the live broadcast is terminated by the platform for no particular reason and your device is very hot at that time, please refer to the following guide to ensure your device is in optimal condition for streaming:

2. In case the live broadcast is terminated according to the community policy of the live platform

Individual live platforms such as YouTube, Facebook, and Twitch have their own policies for community safety. The platform will monitor users’ live streams to maintain community standards. Monitors for live streaming are sometimes handled by operators or automated AI technologies. Therefore, errors may occur in their processing.

Violent or sexual content may be reported by viewers, leading to the termination of the live broadcast. Live broadcasts that persist with still or objectively meaningless images may also be subject to restrictions.

If your live streaming is terminated, please check whether you are violating the community policy of the target live platform. Additionally, if live broadcasting is stopped from the platform even though there is no violation, you can contact the platform’s customer support and take action.

3. In case the live broadcast is terminated according to the maximum streaming time limit of the live platform

Individual live platforms such as YouTube, Facebook, and Twitch have their own maximum time limits for live streaming.

Additionally, live broadcasts streamed from the PRISM app may be forcibly terminated due to their time limit. Examples of time limits are:

• Streaming to Facebook: up to 8 hours.

• There is no maximum time limit for streaming to YouTube. However, auto-archiving is only supported for live streaming videos under 12 hours. YouTube also warns that videos may not be archived at all if the streaming duration exceeds 12 hours.

• Streaming to Twitch: up to 24 hours.

• Streaming to Band: up to 2 hours.

These various live platforms have different time limit policies, which can also be adjusted at any time.

So, if your live streaming has ended and the length was rather long, please check whether the termination was due to the maximum streaming time limit of the live platform.

• Android error code : 4913

• iOS error code : 0 / 15

If you have ever experienced a lack of stability or quality in live streaming using our PRISM mobile app, please refer to the following tips to make better live streaming.

Lower the resolution and frame rate

Smartphones still lack hardware performance, such as CPU and memory, compared to desktops.

To perform live streaming, smartphones must simultaneously handle several tasks: 1) capturing video from the built-in camera, 2) displaying the video on the screen, 3) encoding the video, and 4) streaming the encoded video chunks over the network. Additionally, because smartphones rely on wireless networks, which are often unstable, insufficient network bandwidth can make it impossible to stream the video chunks to the live platform.

If your stream isn’t running smoothly, try lowering the resolution and frame rate gradually. Higher resolutions and frame rates put more strain on smartphones. For instance, under similar conditions, 720p is typically more stable than 1080p, and 30fps is more stable than 60fps.

Turn on the Adaptive bitrate option of the PRISM app

This feature is also known as ABP (Adaptive Bitrate Publish). Even when the network bandwidth is insufficient, it maintains the resolution but gradually reduces the video quality to decrease the size of the video. With the reduced video size, the stream is transmitted to the server more reliably, even under poor network conditions, allowing viewers to enjoy your video stably.

You can enable or disable this option by:

1. Click the button labeled 720p at the channel card.

2. Select the 'Video quality' option at the 'Stream Quality' layer.

3. Set the 'Adaptive' value to On.

Stream where the network is stable

When the Adaptive bitrate option is set to Off, the bandwidth used to generate a 1-second video chunk for each resolution is as follows.

• 1080p : 0.1 ~ 4Mbps or 0.1 ~ 6Mbps

• 720p : 0.1 ~ 2.5Mbps or 0.1 ~ 4Mbps

• 480p : 0.1 ~ 2.0Mbps

• 360p : 0.1 ~ 1.5Mbps

The network bandwidth at the place where you live streaming must exceed this capacity. ​ However, if the Adaptive bitrate option is set to On, there is no problem with streaming video because the app adjusts the size of the video chunks by itself. ​ Of course, even if the video streams smoothly with the help of the Adaptive bitrate option, if the network is insufficient, viewers can watch the video of poor quality.

Use WiFi whenever possible

The results of measuring network performance using the Speedtest.net app, which can be downloaded from the app market, are as follows:

WiFi

• Download : 134.4 Mbps

• Upload : 154.2 Mbps

Data network such as LTE

• Download : 89.2 Mbps

• Upload : 17.8 Mbps

​ As shown, WiFi offers significantly better upload bandwidth compared to data networks. Upload speed is particularly important for live streaming since it involves transmitting video from the smartphone to the server. Keep in mind that the upload speed of data networks is typically only 1/5 to 1/10 of their download speed. For high-quality live streaming, we recommend having at least twice the network bandwidth specified in:

While indoor live streaming usually doesn't require a network check, it’s highly recommended to check network conditions for outdoor streaming or in crowded areas. This is because data network availability might be insufficient in such environments.

Check QoS policy when using unlimited data plans

In general, the following policies apply to unlimited data plans. “The use of data is unlimited, but if it exceeds 100GByte per day, the maximum speed may be limited for the day only. (For example, maximum 100Mbps).” ​ Since the maximum is 100Mbps, the network is actually limited to a lower speed than that, especially the upload speed will be much lower.

If, despite using the unlimited data plan, the quality of a live broadcast deteriorates after a certain point, we can suspect this as the cause of it.

Close other apps before start live streaming

Other apps running in the background can consume your smartphone’s CPU and memory resources, eventually depleting the resources needed for live streaming.

Avoid excessive use of overlays and effects

You can overlay images, videos, and web widgets in our PRISM mobile app, and use various effects such as color filters.

However, these require additional resources from your smartphone, so depending on your smartphone’s performance, the quality of your live broadcasts may be affected. ​ This is because the encoding and transmission of video uses the device’s resources such as CPU and memory, which may incur additional burdens. ​ However, this doesn’t always happen, so remember this tip only if you’re experiencing problems with the quality of your live streaming.

Long streams can overheat your smartphone

The heat can reduce CPU performance and cause delays in live streaming processing.

Removing your smartphone case for a while during live streaming can help reduce heat generation.​

If you're interested in reducing your smartphone's heat, please refer to the following page:

Use latest high-end smartphone

This is because, as mentioned above, your smartphone has to do several things at the same time for live streaming.

They can also handle live streaming faster and with less heat, even with the same usability.

Mobile streaming tips with video

3D VRM VTuber is a type of character live streaming where the streamer goes live using a fictional character instead of themselves, and uses a fully rigged 3D model in the VRM format to animate and interact with viewers in real time.

Since December 2016, when the Japanese YouTuber Kizuna AI began broadcasting using a virtual character, VTubing has rapidly spread within subculture communities. It has experienced even more significant growth entering the 2020s, and nowadays, it has become a mainstream aspect of the media entertainment market.

Meanwhile, live streaming has become one of the primary platforms for VTubers to interact with their fans. Their VTubing content can easily be found on major global live platforms like Twitch, YouTube, and CHZZK.

However, despite the significant growth of VTubing, it has largely been confined to PC environments. This is because the necessary technologies for VTubing — such as avatar players, facial and motion capture, and avatar streaming — have only been available on PCs.

PRISM Live Studio mobile app has support of a 3D VTuber feature, allowing anyone to easily engage in casual VTubing in a mobile environment.

VTuber mode

The PRISM app supports three modes: Screen Live (ScreenCast), Camera Live, and VTuber mode. Select VTuber from the list of live types, which you can see in the center of the image on the left below. Here, we’ll use a VRM model-based 3D avatar, so make sure to select a 3D Avatar from the avatar types.

Supported Devices for 3D Avatar feature on iOS

Avatar selection

You can create their own avatars using VRoidStudio, or download avatars created by others from websites like VRoidHub or Booth to use with the PRISM app’s VTuber feature.

However, the PRISM team has also developed and provided basic 3D avatars to make it easier for you to start VTubing within the app. You can simply choose the avatar you want to use.

Real-time facial expression capture

The PRISM app’s VTuber feature captures the user’s facial expressions in real-time using the smartphone’s front camera and applies them directly to the avatar. The VTuber feature also supports facial functions that enable avatars to display more natural expressions.

Avartar settings

To help you achieve a more natural VTubing experience, the PRISM app’s VTuber feature offers various options. You can position your avatar at the right size and place on the screen, adjust the sensitivity of the avatar’s movements, and fine-tune the lighting’s color and intensity to create an avatar that blends seamlessly with the background.

Emotion / Items / Background

The PRISM app’s VTuber feature applies the user’s facial expressions to their avatar in real-time, while also offering enhanced emotion features such as Joy, Happy, Angry, Sorrow, and Fun to maximize emotional connection with fans.

Additionally, it provides items like desks and microphones, which can be placed in front of the avatar to add personality to your stream, as well as various background images that can be placed behind the avatar to create an overall atmosphere.

VRoid Hub Integration

​The PRISM app’s VTubing feature supports importing VRM models stored on your mobile device. This allows you to easily bring in and use the same VRM models you’ve previously used in PC environments.

In addition, we’ve integrated the most widely-used VRM model distribution platform, VRoidHub, through a login system to make it easier for you to access and use VRM models.

You can easily download avatars you’ve created and registered on VRoidHub or use avatars made by others, and immediately use them for VTubing in the PRISM app.

We will explain situations where live streaming could not start properly because a stream was not created on the YouTube Live Dashboard.

The current error message is displayed in the following two situations:

1. When a stream has not been created on the YouTube Live Dashboard (this is the most common case).

2. When less than 24 hours have passed since you completed verifying your channel for live streaming on YouTube.

The second case refers to the error that occurs if less than 24 hours have passed since you completed YouTube channel verification for live streaming.

If you have used the live streaming feature before, please refer only to the guide for the first case.

1. When a stream has not been created on the YouTube Live Dashboard (this is the most common case).

To live stream on YouTube, a stream must be created on your YouTube channel. If your YouTube channel has more than 50 subscribers, the PRISM app can create a stream using YouTube’s API, which is available to third-party apps like PRISM.

However, if your YouTube channel has fewer than 50 subscribers, YouTube will not allow third-party apps to use this API. In this case, users can manually create a stream by visiting the YouTube Live Dashboard webpage.

In this situation, the PRISM app provides a link to the Live Dashboard webpage in the error guidance dialog. If you click the link, you’ll be taken directly to the Live Dashboard.

Simply visiting the Live Dashboard webpage will automatically create your new stream.

As shown in the image on the left below, when you visit the webpage, you will see a red progress bar at the top of the page. Once the progress bar completes and the screen is filled with content, it means the stream creation is finished.

After stream creation is complete, click the X button in the bottom right corner to close the screen. Then, click the yellow "Go Live" button on the PRISM app's live-ready screen to try live streaming again. Your live streaming should now start successfully.

Although this process can be a bit tedious, if you have fewer than 50 subscribers, you'll need to do this each time you want to stream live. In the PRISM Android app, the app attempts this process automatically on your behalf, but please understand that it may not always work correctly depending on your smartphone’s condition.

Additionally, before starting your live stream, you can create a stream in advance by visiting the Live Dashboard with a web browser on your PC. If you create a stream in advance, the process of moving to the Live Dashboard to create a stream during the PRISM app’s live streaming start will be skipped.

For reference, you can access the Live Dashboard using the following path in your PC's web browser:

1. > YouTube Live Dashboard

2. YouTube > ‘Create’ button at the top right of the screen > ‘Go Live’ button > YouTube Live Dashboard

2. When less than 24 hours have passed since you completed verifying your channel for live streaming on YouTube.

In order to live stream on YouTube, you must wait 24 hours after creating a YouTube channel and completing the YouTube channel verification.

If you have not completed the YouTube channel verification or if you’ve recently completed channel verification and integrated your YouTube account into the PRISM app, the channel information will be displayed as ‘No channel,’ as shown in the figure below.

In this state, if you click the channel area to start live streaming, a guide dialog will appear, as shown in the figure below.

If you follow the dialog instructions to go to the YouTube Live Dashboard, you will see an error message displayed there as well.

However, this is a temporary error screen on the YouTube Live Dashboard, which only appears for about an hour immediately after completing YouTube channel verification.

Once about an hour has passed since completing channel verification, the normal channel information will automatically be set within the PRISM app. If you go back to the YouTube Live Dashboard by clicking on the channel information area, you will see a screen displaying time information that differs from the previous error screen.

In the mobile web browser, you can only see a portion of the screen displaying the time information. However, if you open the web page in a PC web browser, you will see the timer information as shown below.

As mentioned earlier, in order to live stream on YouTube, you must wait 24 hours after completing the YouTube channel verification. Please note that this process follows YouTube’s policy, and therefore our PRISM app must also comply.

After waiting 24 hours, click the yellow ‘Go Live’ button in the PRISM app to start your live stream.

• Android error code : 4226

• iOS error code : 1 / 2

When you create a live stream in PRISM Live Studio, you can add different types of sources such as images, text, music, or chat windows. To keep your live stable and smooth, there are limits on how many sources you can use at the same time. This guide explains the maximum number of each source type and how you can combine them.

*We are reviewing options to increase this limit to allow the use of more overlays in the future.

Android - My Studio Sources (Camera, VTuber mode)

Android - Screencast Sources (Screen mode)

iOS - My Studio Sources (Camera, VTuber mode)

iOS - Screencast Sources (Screen mode)

Usage Examples

IRL Streaming

• Camera feed + 1 chat + 2 images (channel logo, banner)

Game Streaming

• Screen capture + 1 chat + 2 images (channel logo, banner) + 1 text (notice)

VTuber Streaming

• 1 3D avatar + 1 chat + 2 text items (stream title, support info) + 1 QR code (support link)

Tips

• Minimize the Number of Sources Adding too many sources can overload the stream. Place only the essentials for a more stable broadcast.

• Playback Sources Are Not Compatible Simultaneously Music, video, and image playlists cannot be played together. Choose only one type depending on your stream’s purpose.

• Check OS Limitations The maximum number of supported sources may differ between Android and iOS. Verify in advance and design your layout accordingly.

This post provides guidance on resolving issues when live streaming to Facebook fails to start properly.

If you integrate your Facebook account with the PRISM app, you can live stream to your Facebook timeline or page. However, if your profile or the page you are streaming to does not meet Facebook’s basic requirements, streaming will not start.

To stream to a timeline or page, it is essential to grant the necessary permissions to the app. Additionally, if you want to stream to a page you didn’t create, you must configure additional settings within that page.

Streaming may also fail if Facebook has restricted your live streaming feature. In this case, the issue cannot be resolved through this post, and you must contact Facebook’s customer service for assistance.

This post covers the following five topics:

1. Facebook streaming requirements

2. Facebook account integration

3. Streaming to a Timeline

4. Streaming to Pages

5. Streaming to Groups (Currently not supported)

1. Facebook Streaming Requirements

The following requirements take effect on June 10, 2024, due to changes in Facebook’s Open API policy:

• Your profile must be at least 60 days old to go live on Facebook. This applies to both timeline and page streaming.

• You must have at least 100 followers to go live from your profile. This requirement applies to profiles using Professional Mode as well as page streaming.

• Professional Mode:

If your Facebook profile does not meet these requirements, streaming via the PRISM app will not work. Please try again after meeting both requirements.

2. Facebook account integration

This guide explains how to integrate your Facebook account with the PRISM app. Please refer to the explanations accompanying the attached images.

Click the [Ready] button in the [LIVE] tab of the PRISM app. If no channels are currently integrated, you will see a list of available platforms.

Click the [Facebook] icon to open the Facebook menu, then click the [Connect Facebook] button (blue background) to log in and connect your Facebook account.

This screen requests permission for the PRISM app to stream to Facebook. The necessary permissions are pre-selected by default, so click the [Continue as] button to proceed.

This screen allows you to set the audience visibility for your live stream. You can adjust privacy settings within the PRISM app after integration, but the settings selected here will take priority. To ensure your selected audience visibility applies correctly, choose [Public] and click the [Continue as] button.

When streaming to timelines or pages, you will only be able to see viewer comments within the PRISM app if both the audience setting on this screen and the privacy setting in the PRISM app are set to [Public].

Once these steps are completed, your Facebook account is successfully integrated with the PRISM app. Click the channel card (shown in the left-side image) to access Facebook streaming settings, where you can configure streaming options for your page.

To stream to a page, click the [Choose where to post] section (shown in the right-side image).

Navigate to the [Choose where to post] menu and select [Page]. The app will then request permission to stream to the selected page.

Once all required permissions are granted, a list of available pages will appear, allowing you to choose where to stream.

3. Streaming to Timeline

After selecting Timeline, click the [Go Live] button to start streaming live on your Facebook timeline.

4. Streaming to Pages

As of December 16, 2023, Facebook has introduced new restrictions on live streaming to Pages.

Due to Facebook’s updated policy, the PRISM app is currently unable to process live streaming for newly created Pages or Pages without an established presence. Please note that this is a restriction imposed by Facebook’s policy, and the PRISM app has no control over it.

Facebook does not officially disclose the exact timeframe required for a Page to be eligible for live streaming or the level of engagement needed. However, it is estimated that a Page must be at least 60 days old and have at least 100 followers to qualify.

Once you integrate your Facebook account with the PRISM app, any Pages you have created will appear in the app’s list. Even if you didn’t create the Page yourself, it will still be displayed in the list if you have an Admin or Editor role.

However, simply following a Page will not make it appear in the list. If you have a Moderator, Advertiser, or Analyst role, the Page may appear in the list of streaming targets, but you will not be able to stream due to Facebook’s platform policy.

If you attempt to stream without the necessary permissions, you will receive the following error message:

“(#200) Subject does not have permission to create live video on this Page.”

This means that to stream to a Page, you must either create the Page yourself or be assigned an Admin or Editor role by the Page manager.

Page Admins can grant Admin and Editor roles through the Page settings.

Go to the [Page Roles] section under the [Settings] menu.

You can assign a specific Facebook user as an [Admin] or [Editor] by using the [Assign new Page role] option on the right side. Once a user is assigned as an [Admin] or [Editor], they will be able to stream live to the Page.

Lastly, please note that live streams to the Page will be shown in the Videos tab of the Page.

5. Streaming to Groups (Currently not supported)

The PRISM app has supported streaming to groups for a long time, but unfortunately, starting April 24, 2024, streaming to groups from the PRISM app will no longer be supported due to changes in Facebook’s Open API policy.

Deprecating Facebook Groups API (January 24, 2024)

The Facebook Groups API is deprecated in v19 and in 90 days will be removed from all versions. This deprecation includes all Permissions (publish_to_groups, groups_access_member_info) and Reviewable Features (Groups API) associated with the Facebook Groups API.

If previous versions of the PRISM app fail to adapt to these changes in external platform APIs, consider re-integrating Facebook within the PRISM app if streaming to timelines and pages, rather than groups, causes issues.

However, this change does not mean that streaming to Facebook groups is completely impossible within the PRISM app. Facebook group streaming through the PRISM app is still possible by following these steps:

1. Access the Facebook website.

2. Navigate to the target group for streaming on the Facebook website.

3. Click [Create Post].

4. Click on the More button and select [Live Video].

You can stream live with a virtual 2D character based on your own style using the PNG Tuber option in the PRISM app. It is a feature that allows creators to interact with their audience as a living character using a variety of facial expressions and gestures, and you can learn more about how to use it, including different emotions and specific gestures, at the following page:

We provide twelve default characters in the app to help you get up and running quickly, but a lot of people like to use their own characters for live streaming.

Most of the live streaming these days takes place in a situation where the streaming device is mounted some distance away in front of the streamer. As a result, streamers have had some difficulty accessing or controlling the device’s features during live streaming.

PRISM app supports remote control function that can remotely control the other PRISM app. And this feature can be used in various combinations, such as:

• Streaming with PRISM mobile + remote control with PRISM mobile • Streaming with PRISM Windows + remote control with PRISM mobile • Streaming with PRISM mobile + remote control with PRISM Windows (to be supported in the future)

PNG Tuber is a type of character live streaming where the streamer goes live using a fictional character instead of themselves, and uses a set of images to represent the fictional character.

​Character live streaming began in 2016 with the unique advantage of utilizing a streamer’s character with a new identity to meet viewers, and has seen a dramatic increase in user volume since 2019.

However, since live streaming of characters, including PNG Tuber, requires special equipment or separate softwares, live streaming has been mainly conducted based on PC apps, and due to this situation, character live on mobile apps has not been familiar to us.

By using the PRISM app, anyone can easily become a PNG Tuber on the mobile app without any hassle and preparation.

Flow of using the PNG Tuber

PNG Tuber is live streaming with a virtual character as the protagonist, but its purpose is the same as any other live stream to connect and interact with viewers.

Your character needs to express emotions that fit the story you’re telling, and PNG Tuber makes this possible by selecting and using a set of images for each emotion.

The PRISM app also allows users to register their own set of PNG Tuber character images, but to make it easier and faster to get started with PNG Tuber, the app provides five default characters. And they have five set emotions by default: happy, joy, surprised, sad, and angry. And you can change your emotional expression by clicking on the individual emotion buttons as you livestream. ​ For each of these five emotions, the following four state images are being used:

• Image with eyes open, mouth closed

• Image with eyes open, mouth open

• Image with eyes closed, mouth closed

• Image with eyes closed, mouth open

Therefore, if you want to prepare your own characters to use instead of the default characters provided by the PRISM app, we recommend that you prepare a total of 20 images (5 emotions x 4 states) as shown in the example above.

However, five emotions and four states for each emotion are sometimes not enough to connect with your audience. While you can add more than five emotions to the characters, the PRISM app takes it further by supporting an additional feature called motion.

You can give your character repetitive movements through motion features that can be applied to each emotion. And the PRISM app has a total of five forms of motion. And you can even apply a different motion for when the mouth is open and closed.

There's a lot more to the PNG Tuber feature in the PRISM app than this. ​For example, you can set a background and change it on the fly while you’re live, and we also support integrations that allow you to use PNG Tuber not only for mobile streaming, but also for PRISM Windows Live Streaming.

More details can be found in the section below.

VTuber Mode

The PRISM app supports three modes: Screen Live (ScreenCast), Camera Live, and VTuber mode. Select VTuber from the list of live types, which you can see in the center of the image on the left below. Here, we’ll use a PNG Tuber, so make sure to select a 2D Avatar from the avatar types.

Vtuber Setting

When you enter the VTuber mode, you’ll see a character from one of the default characters provided by the PRISM app immediately set up on the screen. (The number and type of basic characters may change.)

When you look at the middle part of the picture on the left, you can see the Settings button, and once you click that button, you can enter the VTuber setting screen. On the VTuber setting screen, you can check the 5 default characters provided by the PRISM app by swiping.

At the left end of the character list, you’ll find a card that allows you to add new characters (avatars).

At the top of the card, Preview and Source tabs are located, and you can register image sets for each emotion guide in the Source tab. This image set is for changing the shape of the eyes and mouth, and it is recommended to prepare one set consisting of 4 images as shown below:

• Image with eyes open x mouth closed

• Image with eyes open x mouth open

• Image with eyes closed x mouth closed

• Image with eyes closed x mouth open

If you click each state of the source, it will switch to the media selection mode where you can attach images. And as shown on the screen, you can register each state image in the order you selected. The image setup process will be easier if you have saved the images in the same place.

If you switch to the preview tab after registering all 4 status images, you can check the status change in the corresponding emotion in the card. And, using the volume bar fixed on the left side of the card, you can set the voice volume value that reflects the shape of your mouth.

​At the very bottom of the screen, you can see the ‘Emotion’ text button. Once you click on it, you can enter the emotion setting screen where you can set the emotion list itself. Click the emotional emoticons at the bottom of the screen one by one and set the status images for each emotion.

Emotion Setting

As mentioned earlier, the default characters provided by the PRISM app have five basic emotions: happiness, joy, surprise, sadness, and anger.

However, you can make changes such as adding or deleting this emotion list of your own character, and you can do that in the emotion settings screen that appears on the screen.

So, click the plus button to see a new emotion slot appear, then select and add a suitable emotion from the emotion emoji list at the bottom. You can see that an emoji has been added that looks greyed out.

You can also enter the emotion list editing mode by long-pressing the emotion list area.

Here you can delete previously registered emotions or adjust the order in which emotions are placed. When all adjustments are complete, click the Done button at the top right to complete the application.

Placing character on the screen

PNG Tuber character overlays can be positioned by dragging and dropping, just like normal overlays available in the PRISM app. And you can also adjust its size and rotation using pinch & zoom.

So, after selecting your character, place it in the position and size that best suits your streaming screen area, and start streaming your character.

Emotion and background

In order to quickly switch and utilize these set emotions during live streaming, it is recommended to keep the emotion menu open.

You can see Emotions, Items and Backgrounds buttons in the middle of the image on the left. If you click the button, the emotion list is exposed at the bottom of the screen. Choose appropriate emotions that fit the communication situation with viewers.

You can also change the background using the Emotions, Items, and Backgrounds buttons as shown in the image above. You can register several backgrounds in advance and change them later, just like emotions.

If you register backgrounds that express various spaces, you will be able to create effects like scene transitions in movies or cartoons.

Volume bar settings

In VTuber mode, you can see the volume bar on the left side of the screen.

You will remember that you registered 4 state images when registering emotions earlier. And half of the four state images were images with the mouth open, and the other half were images with the mouth closed.

Transitions between open and closed mouth images respond to the streamer’s voice volume and are handled automatically. And for now, you can set the volume of the voice that the processing responds to through the volume bar.

If you set the volume too low, the character may not open its mouth while speaking, and if you set the volume too high, the character may keep its mouth open all the time.

Therefore, set appropriate values in advance through testing, and proceed with live streaming while changing the appropriate settings according to the situation.

Avatar Management

A More button is provided at the top right of each avatar card in the settings menu. If you click the button, you can duplicate the avatar, export the avatar file (extension .prismvt), or delete the avatar.

Additionally, if you export the avatar file that you created in the PRISM app, you can use it as-is on other devices by importing the file.

You can utlize this feature when you change devices or share avatar files with friends.

Utilizing Avatars in the CONNECT function

Through the CONNECT function of the PRISM mobile app, the camera preview of the PRISM mobile app could be used as a video source in the PRISM Windows app.

In addition to this, the VTuber screen can also be used as a source in the PRISM Windows app.

As shown in the image below, select Vtuber Share in the CONNECT tab to use the PNG Tuber function in the PRISM Windows app.

Default characters

​In the PNG Tuber function of the PRISM app, you can register and use the character image sets you have prepared yourself, as described above.

< How to prepare your own character >

• Draw them yourself using drawing tools.

• Request a professional who draws characters.

• Or you can draw it using an AI tool (these have been released a lot recently!)

However, those without experience might have difficulties to set up. PRISM app is providing 12 default PNG Tuber characters.

In this page we're going to show you only 3 characters. But you can check out remain characters in the PRISM app yourself, then start streaming PNG Tuber live using your favorite characters.

We haven’t named the characters yet. Names are being suggested in the discussions channel of the PRISM official Discord server below, so join the server and come up with cool names. Who knows your suggestion might be chosen!
