# Using Screencast

PRISM app supports Camera-Live using the device’s camera, Screen-Live for sharing your device’s screen, and VTubing-Live with your own character avatar. Among them, the **ScreenCast** feature is primarily utilized for game streaming, enabling live streaming directly from smartphones by broadcasting the device’s screen.

Furthermore, the ScreenCast feature in the PRISM app allows users to overlay various sources onto the broadcast screen by **Scene editing**, adjust the device and microphone volume separately, and enable a screensaver to protect private information during live streams.

To enter ScreenCast mode, click on the **LIVE** tab in the bottom menu, then select **Screen** mode from the available options **(Screen, Camera, VTuber)**.

On the App Store, there are various portrait and landscape games. The PRISM app allows users to capture the screen in both **portrait** and **landscape** modes. Additionally, regardless of the screen orientation, it supports both **16:9** and **9:16** aspect ratios for streaming videos.

Once you have configured your broadcast settings, click **Go Live**.

### Web source <a href="#id-378e" id="id-378e"></a>

Web source overlays in live streams are primarily used for displaying donation alerts or other web-based elements. However, due to limitations of the iOS operating system, these overlays are only visible to viewers and will not be displayed on the broadcaster’s screen.

<figure><img src="https://miro.medium.com/v2/resize:fit:1400/1*vnoADU58CN0itwzZfUlqvg.png" alt=""><figcaption></figcaption></figure>

### Image source <a href="#fa3b" id="fa3b"></a>

Just like in regular camera live streams, you can overlay images onto ScreenCast streams. You can select images from your device’s gallery.

<figure><img src="https://miro.medium.com/v2/resize:fit:1400/1*kSC00ud2S4L8G9kZbLYdcA.png" alt=""><figcaption></figcaption></figure>

### 2D / 3D Avatar source <a href="#id-10db" id="id-10db"></a>

You can use PNG Tuber characters provided by the PRISM app with the Screencast feature, allowing you to display an avatar that reacts to your voice during game streaming. The character’s mouth movements sync with your voice, creating a more interactive and engaging experience for viewers. For more details about PNG Tuber, refer to the following page:

* [adopting-png-tuber](https://guide.prismlive.com/mobile/guides/vtuber/adopting-png-tuber "mention")

However, changing the PNG Tuber’s emotions in real time is not supported during game streaming. Instead, you can set a default emotion in the avatar settings menu beforehand. Once configured, your chosen emotion will be applied when using the PNG Tuber in the Screencast feature.&#x20;

<figure><img src="https://miro.medium.com/v2/resize:fit:1400/1*jV3AaAG_e5MYFMdpETBjhQ.png" alt=""><figcaption><p>The <strong>Screencast</strong> feature in the PRISM app supports PNG Tubers using images.</p></figcaption></figure>

### Screen source <a href="#id-6e30" id="id-6e30"></a>

You can use your device’s captured screen as an overlay on your live stream. The captured screen can be placed anywhere in the layout and resized as needed, allowing you to position the screen or game area in the most suitable way for your viewers.

Since the screen source size is typically large, it may be helpful to lock the source in the layer menu after resizing and positioning it. This prevents accidental adjustments and ensures a stable streaming layout.

<figure><img src="https://1019928184-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlISC5rfB4Hnmbsjf8phq%2Fuploads%2FXfqmM4O19DraNd8Gzyz9%2Fscreencast16.jpg?alt=media&#x26;token=397e2e25-812e-4b25-9380-97ad5ed92167" alt=""><figcaption></figcaption></figure>

## Floating widget (Android only)

In the ScreenCast mode of the PRISM Android app, a **Floating widget** provides easy access to key streaming functions. Using the **Chat** tab, you can view viewer chats and donations directly on your game screen. The **Thumbnail** tab allows you to preview how your current layout appears to viewers, ensuring your stream looks exactly as intended. Additionally, you can control audio settings and activate the screen saver from the widget.

{% hint style="warning" %}
Floating widgets are not available on iOS due to OS limitations.
{% endhint %}

***

## Front camera overlay (Android only) <a href="#id-2ef9" id="id-2ef9"></a>

The Floating widget in the PRISM Android app also supports a **Front camera overlay**, allowing streamers to include their facecam in the broadcast as Picture-in-Picture (PiP). This feature enhances viewer engagement by displaying the streamer’s face alongside the gameplay.

The PiP window is fully adjustable—you can pinch to zoom for resizing and drag to reposition the camera overlay anywhere on the screen for optimal placement.

***

## ScreenCast notification (iOS only)

Unlike the PRISM Android app, which provides real-time information through a Floating widget, the PRISM iOS app does not support this feature due to iOS system limitations.

As an alternative, the iOS app provides real-time notifications for key events such as viewer chats, subscriptions, and Super Chat messages during game streaming. You can customize notification settings in the app’s Settings menu, allowing you to stay informed and interact with your viewers more effectively.
