broadcasts or if viewers of the web broadcasts notice delays and you have
determined that the delays are not caused by low Internet bandwidth. The
delays could be caused by high CPU usage on the video capture workstation
resulting in the video capture workstation not being able to process all image
data. Lossless compression increases CPU usage, so you can reduce CPU
usage during web broadcasting by reducing lossless compression.
Note: You cannot change web broadcasting compression during a web broadcast.
You must stop the broadcast, adjust the settings and then start the broadcast again.
