Live encoder settings, bitrates and resolutions

Video resolution

Based on your available outbound bandwidth, choose the one highest quality from below that you can reliably stream. Remember to account for your backup stream. YouTube will automatically create all of the lower qualities.

Example: If you have 10M dedicated bandwidth for your encoder, you could safely choose to stream 720p quality. 4M for primary encoder, 4M for backup encoder, with room for overhead.
