Optimal definition profiles
Under ideal lighting conditions the bandwidth requirements can
be substantially reduced with the optimal definitions profiles.
Generally, we recommend the Optimal Definition set at Normal.
If lighting conditions are good we recommend that you test
the endpoint on the various Optimal Definition settings before
deciding on a profile.
Go to Advanced configuration (menu on screen or web interface)
to set the optimal definition profile:
• Navigate to Video > Input > Source [1..n] >
OptimalDefinition > Profile and select a profile.
You can set a resolution threshold below which the maximum
frame rate will be 30 fps.
Go to Advanced configuration (menu on screen or web interface)
to set the threshold:
• Navigate to Video > Input > Source [1..n] >
OptimalDefinition > Threshold60fps and select a
threshold.
The video input quality settings must be set to Motion to ensure
the Optimal Definition to work. With the video input quality set
to Sharpness, the endpoint will transmit the highest resolution
possible, regardless of frame rate.
Go to Advanced configuration (menu on screen or web interface)
to set the input quality:
• Navigate to Video > Input > Source [1..n] > Quality and set
the video quality parameter.
You can read more about the video settings in the Advanced
configuration settings chapter. Go to:
Advanced configuration
High (720p60)
Typically used in dedicated video
conferencing rooms. Requires good
lighting conditions for a good overall
experience.
Under ideal conditions the bandwidth
requirements can be reduced by up to
50%.
Medium (w576p60)
Typically used in rooms with better
than normal, and consistent lighting.
The bandwidth requirements can be
reduced by up to 25%.
Normal (w448p60)
This setting is typically used in office
environments where the environment is
normal to poorly lit.
Generally, we recommend the Optimal
Definition set at Normal.
