Selecting Priority of Quality Metrics for Source Video
You can favor sharpness or motion as a priority for the quality of primary and presentation
video that the Avaya system sends to the far end during a call. If you favor sharpness by
selecting a smaller number for the
Administrator Preferences : Video : Video Quality :
Primary Video Motion
preference, in lower bandwidth calls the system sends the primary
video at a lower frame rate and a higher resolution. The default value (10) favors motion.
Consider adjusting this preference if bandwidth is limited.
If you are sending a presentation, select the priority for the quality of the presentation video
in
Administrator Preferences : Video : Video Quality : Presentation Video Sharpness
.
The default value (10) favors sharpness. Typically, presentation data does not include
motion (for example, a spread sheet or slide show). When you favor motion for presentation
video by selecting a smaller number for this preference, the system sends the video at a
higher frame rate and a lower resolution.
Adjusting Video Encoder Quality
You can adjust the quality of the video image sent to the far end during a call by specifying a
relative lower or higher resolution in the
Administrator Preferences : Video : Video
Quality : Video Encoder Quality
preference. Moving the slider to the right decreases the
resolution of the video sent to the far end and improves the quality of the video image.
Consider using this preference to make minor adjustments to the quality of the video image
sent to the far end.
Disabling Access to the Local Directory

modify these entries. For more information about the local directory, refer to the
