Introduction

Adjust the video quality to call rate ratio

Video input quality settings
When encoding and transmitting video there is a trade-off
between high resolution (sharpness) and high frame rate (motion).
The Video Input Connector n Quality setting 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.
Optimal definition profile
The optimal definition profile should reflect the lighting conditions
in the video conferencing room and the quality of the camera
(video input source). The better the lighting conditions and the
better the quality of the camera, the higher the profile should be
used.
Generally, the Medium profile is recommended. However, if the
lighting conditions are very good, we recommend that you test
the endpoint on the various Optimal Definition Profile settings
before deciding on a profile. The High profile may 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.
The resolution and frame rate must be supported by both the
calling and called devices.
Sign in to the web interface and navigate to
1. Go to Video > Input > Connector n > Quality
quality parameter to Motion (skip this step for Connector 1
(integrated camera).
2. Go to Video > Input > Connector n > OptimalDefinition >
Profile and choose the preferred optimal definition profile.
