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.
The Video Quality Optimized settings are described in the section"The CP Resolution 
.
Manual
The administrator adjusts the sliders to accommodate local conferencing requirements.
Sharpness / Motion Resolution Slider Panes
Sharpness and Motion are Video Quality settings that are selected per conference and are 
defined in the conference Profile and they determine the resolution matrix that will be 
applied globally to all conferences according to the selection of Sharpness or Motion. The 
resolution matrix for Sharpness or Motion is determined by the resolution configuration and 
can be viewed in the Resolution Configuration sliders.
System Resource usage is affected by the Resolution Configuration settings.
Example
As shown in following diagram:
Moving  the  HD720p30 resolution slider from 1024kbps to 1920kbps increases the 
minimum connection threshold line rate for that resolution. Endpoints connecting at 
line rates between 1024kbps and 1920kbps that would have connected at 
HD 720p30 resolution will instead connect at SD 30 resolution. Each of the affected 
endpoints will connect at lower resolution but will use 1.5 system resources instead of 3 
system resources.
Moving  the  HD1080p30 resolution slider from 4096kbps to 2560kbps decreases the 
minimum connection threshold line rate for that resolution. Endpoints connecting at 
line rates between 2560kbps and 4096kbps that would have connected at 
HD 720p30 resolution will instead connect at HD 1080p30 resolution. Each of the 
affected endpoints will connect at higher resolution but will use 6 system resources 
instead of 3 system resources.
Use this option when the priority is to use higher video resolutions while decreasing the number of 
participant connections.
