• Resource Optimized
System resource usage is optimized by allowing high resolution connections only at
high line rates and may result in lower video resolutions (in comparison to other
resolution configurations) for some line rates. This option allows to save MCU
resources and increase the number of participant connections.
• Video Quality Optimized
Video is optimized through higher resolution connections at lower line rates increasing
the resource usage at lower line rates. This may decrease the number of participant
connections.
Video Resource Usage
Video resource usage is dependent on the participant’s line rate, resolution and Video
Quality settings.

The following illustrations show a comparison between the resolutions used at various line
