a.Adjust your video/audio bitrate based on your internet connection and your viewers’ internet connections. A good rule of thumb would be to have your internet connection’s upload speed at three times the total output bitrate. For example, if you need to stream at 1mb bitrate, you would need a 3mb upload speed from your provider just to leave some headroom and make sure everything goes smoothly.
b.A 500-1200kbps total bitrate will deliver a high quality stream (again, depending on your internet connection and the viewers internet connection) and is a maximum recommendation for streaming purposes. Encoder should be x264.
c.A 128kbps audio bitrate will deliver a high quality audio stream. 96kbps or 64kbps is recommended for users with lower end internet connections.
d.OBS can also record your stream into a local file--you can define where that file is stored into the “Recording Path” field.
