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 on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDefinition
> Profile and select the optimal definition profile.
You can set a resolution threshold below which the maximum
frame rate will be 30 fps.
Go to Advanced Configuration on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDefinition
> Threshold60fps and select a threshold.
The video input quality settings must be set to Motion for 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 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
configuration section. Go to: Advanced configuration

conferencing rooms. Requires good
lighting conditions for a good overall
experience.
Under ideal conditions the bandwidth
requirements can be reduced by up to
50%.

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.
