Optimal definition profiles
Under ideal lighting conditions the bandwidth (call rate) 
requirements can be substantially reduced. 
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.
In general, we recommend the optimal definition profile 
set to Normal. However, if lighting conditions are good we 
recommend that you test the endpoint on the various Optimal 
Definition Profile settings before deciding on a profile.
Go to System Configuration on the web interface and 
navigate to 
Video > Input > Source [1..n] > OptimalDefinition > 
Profile 
to choose the preferred optimal definition profile.
You can set a resolution threshold to determine when to allow 
sending video at 60 fps. For all resolutions lower than this 
threshold, the maximum transmitted frame rate will be 30 fps; 
for higher resolutions, 60 fps will be possible if the available 
bandwidth is adequate.
Go to System Configuration on the web interface and 
navigate to 
Video > Input > Source [1..n] > OptimalDefinition > 
Threshold60fps 
to set the threshold.
The video input quality settings must be set to Motion for the 
optimal definition settings to take any effect. With the video 
input quality set to Sharpness, the endpoint will transmit the 
highest resolution possible, regardless of frame rate. 
Go to System Configuration on the web interface and 
navigate to 
Video > Input > Source [1..n] > Quality 
to set the 
video quality parameter to Motion.
You can read more about the video settings in the 
chapter.

High
Typically used in dedicated video 
conferencing rooms. Requires very good 
lighting conditions and a good quality 
video input to achieve a good overall 
experience. 
Under ideal conditions the bandwidth 
requirements can be reduced by up to 
50% compared to Normal.
Medium
Typically used in rooms with good and 
stable lighting conditions and a good 
quality video input.
The bandwidth requirements can be 
reduced by up to 25% compared to 
Normal.  
Normal
This setting is typically used in office 
environments where the room is normally 
to poorly lit.
