This is one of the most important steps in starting a stream. The Bitrate of your stream is the primary factor in determining the quality of your broadcast.
This is something that you can change at any time however, so for now, just use these standard bitrates:
Audio only - mostly talk: 20 kbps
Audio only - mostly music: 37 kbps
Audio & Video - 282 kbps
Select your bitrate by placing a check in the box beside it. Make sure you only have one bitrate selected.
Click "Next" and proceed to Step 7.
