Advanced setup
Procedure
1. Click Preferences > Video > Configure.
The Video Configuration window appears.
2. Select H.263 Codec from the Preferred Video Codec drop-down menu.
If your video camera does not support a video capture format that is usable by the H.263
CODEC, then the H.263 CODEC does not appear as a choice.
3. Select one of the Codec Quality Settings or click Config. Use custom video configurations
with care.
The combination of a large video image size, high quality CODEC setting, and high Frames
Per Second (FPS) produces video transmission rates over 1 Mbit/s and erodes network and
PC performance. Avaya recommends that you use one of the pre-defined video
configurations.
4. Use the guidelines in the table to adjust the custom video configuration.

Description
This specifies the maximum bitrate that the encoder transmits, not
including header information. Drag the slider or enter a value in the
text box.
This value allows you to change the interval of sending keyframes,
which could reduce the bandwidth requirement at the cost of quality.
The default value is 8 (medium, high, and very high quality settings),
and you can specify values between 1 and 300.
This value allows you to improve the frame rate of the video at the
cost of quality. A lower value for Video Fluidity produces more
choppy video motion, with a higher image quality for each frame of
video. The default value is 100 (all quality settings).
This option improves video compression, but the decoded video is
susceptible to artifacts due to packet loss.
