Resolution and Frame Rates for Content Video
The high frame rates with high resolution apply only to point-to-point calls above 832 kbps. In addition, you
must set Optimized for value of your Camera input to Sharpness. Low frame rates apply if your call does
not meet these requirements.
For multipoint calls, the maximum resolution and frame rate for content is 720p @ 30 fps.
