Video Input Source [1..2] OptimalDefinition Profile

The Video Input Source Quality setting must be set to Motion for the optimal definition settings
to take any effect.
The optimal definition profile should reflect the lighting conditions in your room and the quality
of the video input (camera); the better the lighting conditions and video input, the higher the
profile. Then, in good lighting conditions, the video encoder will provide better quality (higher
resolution or frame rate) for a given call rate.
Generally, we recommend using the Normal or Medium profiles. However, when the lighting
conditions are good, the High profile can be set in order to increase the resolution for a given
call rate.
Some typical resolutions used for different optimal definition profiles, call rates and transmit
frame rates are shown in the table below. It is assumed that dual video is not used. The
resolution must be supported by both the calling and called systems.
Use the Video Input Source OptimalDefinition Threshold60fps setting to decide when to use the
60 fps frame rate.

Requires user role: ADMIN
Value space: <Normal/Medium/High>
Normal: Use this profile for a normally to poorly lit environment. Resolutions will be set rather
conservative.
Medium: Requires good and stable lighting conditions and a good quality video input. For
some call rates this leads to higher resolution.
High: Requires nearly optimal video conferencing lighting conditions and a good quality video
input in order to achieve a good overall experience. Rather high resolutions will be used.
