Controlling video quality

You can tune video quality in each output in an Elemental Live event. You tune the video quality by setting parameters that are in the output section of the event: in the relevant output group, choose an Output, choose a Stream, choose the Video tab, then open the Advanced section.

The following list identifies the parameters that affect video quality. The list also specifies the section in this guide that describes the parameter.
