The encoder profile default settings are something like this.
Most web server streams use the
Streaming 0 profile. Note that UI3 has its own system of encoder profiles which inherit some settings from Streaming 0 and override others. UI3 specifically overrides the bit rate limit and output frame size with each of its default profiles. UI3's "VBR" profiles additionally override Quality (20%).
If you want a better group stream (multi-view) then a big part of the puzzle is to find where you can resize the frame:
The default group frame size varies based on your camera layout but it is usually around 1280x720 or smaller, which sucks on a large display.
