Camera Settings Optimization Guide
When using PRISM Lens for streaming, some cameras may experience performance limitations that cause the output frame rate (FPS) to drop below the preset value or become unstable, resulting in video stuttering or delays.
To ensure smooth video, we recommend checking your hardware environment first, and then adjusting the camera settings as needed.
1. Check the Hardware Environment
System Resource Usage
Check your PC’s CPU and GPU usage. If usage is above 80%, close high-consumption programs to free up performance.
USB Camera Connection
When using a USB camera, connect it to a USB 3.0 port to avoid bandwidth limitations that may cause FPS drops.
Camera Connection Status
Some cameras may encounter interruptions during capture. Try unplugging and reconnecting the camera.
2. Adjust Camera Settings
In PRISM Lens, you can configure resolution, frame rate, and video format from the menu next to the device selection dropdown.

Recommended Adjustment Order
If you experience stuttering or unstable FPS, adjust settings in the following order for best results:
Lower the resolution and check if performance improves.
Reduce the frame rate (recommended not lower than 25 FPS).
Select a raw format (RGB / YUY2 / NV12 / I420) to improve quality and stability at lower resolutions.
(1) Resolution Settings
Recommended: 1280×720 (720p)
Most cameras can stably output 30 FPS at 720p.
If stuttering persists at 720p, try a lower resolution.
(2) Frame Rate Settings
Recommended: 30 FPS — suitable for most scenarios.
If 30 FPS still causes stuttering, you may lower the frame rate, but it’s best not to go below 25 FPS.
Since PRISM Lens supports a maximum output of 30 FPS, setting higher values is not recommended as it adds unnecessary performance overhead.
(3) Video Format Selection
Raw formats (RGB / YUY2 / NV12 / I420)
No decoding required, low latency, higher quality and stability.
Recommended for low-resolution scenarios.
Compressed formats (MJPG / H.264)
Smaller data size, more suitable for high-resolution streaming.
May depend on camera encoding capability and system decoding performance.
3. Additional Recommendations
If issues persist, try updating your camera driver.
