Streaming from OBS to Recast using RTMP

This guide includes the best settings to use when streaming from OBS to Recast via an RTMP protocol.

1. Video

• Resolution: 1280x720
• Common FPS: 25 or 50fps (suggesting this as UK standards and can help avoid flickering with lights in the kind of venues you use. 50 if you have decent internet bandwidth, 25 if not)

2. Output

• Video bitrate: Suggest 5000 for a 25fps stream or 7000 for a 50fps (this is very dependant on your internet upload speeds, drop if you notice lots of black, dropped frames on the stream)
• Encoder: Use hardware encoder if available
• Audio bitrate: 192 (this is probably the default)
• NB: This screen is also where you can turn a local recording on by default.
