Elgato Facecam is designed to operate at 60 frame-per-second for a smooth video experience at all times.
With manual settings, it is possible to use a lower frame rate such as 30 frames-per-second to achieve better image quality in low light conditions or reduce USB bandwidth.
Facecam has two frame rate modes:
- Constant Frame Rate
- Variable Frame Rate
Constant Frame Rate
In Constant Frame Rate (CFR) mode, Facecam video will always be 60 frames-per-second (FPS), no matter the lighting conditions.
To achieve CFR, these settings are required:
- In an application or program, set the frame rate of Facecam to 60fps
When an application sets Facecam to 60fps, Facecam will operate in CFR mode and will at all times output 60fps.
Variable Frame Rate
In Variable Frame Rate (VFR) mode, Facecam video will have a frame rate range between 15 to 30fps. Facecam will dynamically change the frame rate to achieve a brighter image by reducing the shutter speed to let in more light to the sensor, thus increasing brightness.
To activate VFR mode, these settings are required:
- In an application or program, set the frame rate of Facecam to 30fps.
When an application sets Facecam to 30fps, Facecam will operate in VFR mode and adjust the frame rate as needed given the current lighting conditions.
