Optimal denition proles
Under ideal lighting conditions the bandwidth requirements
can be substantially reduced with the optimal denitions
proles.
Generally, we recommend the Optimal Denition set at
Normal.
If lighting conditions are good we recommend that you test
the endpoint on the various Optimal Denition settings before
deciding on a prole.
Go to Advanced Conguration on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDenition
> Prole and select the optimal denition prole.
You can set a resolution threshold below which the maximum
frame rate will be 30 fps.
Go to Advanced Conguration on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDenition
> Threshold60fps and select a threshold.
The video input quality settings must be set to Motion for the
Optimal Denition 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 Conguration on the web interface and
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
conguration section. Go to:
Advanced conguration
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 oce
environments where the environment is
normal to poorly lit.
Generally, we recommend the Optimal
Denition set at Normal.
