During my Collaborate Ultra session, what can I do to improve quality of the audio, video, and materials participants receive?
Ask participants who don't currently need to show video to turn their cameras off.
Sharing video takes up bandwidth. If a student does not need to share their camera then there is less information to be distributed to all of the participants.
Tune your PowerPoint presentation(s).
Preparing your PowerPoint presentations for Collaborate will help Collaborate's whiteboard display your slides more quickly, with better quality, and using less bandwidth.

Observe the best practices for application sharing.
Application sharing can demand a great deal of bandwidth, but by observing some application sharing tips, you can reduce bandwidth usage and increase both performance and quality.
