Setting your bitrates
When live streaming, you need to make sure you're broadcasting audio and video content within the limits of your connection (more specifically, its upload capacity).
As a rule of thumb, you always want to be broadcasting a video bitrate and audio bitrate 20% lower than your upload speed. To find your upload speed, go to Speedtest.net and run a speed test. Once you have your upload speed, you can then calculate the correct video and audio bitrates you'll need to use in your encoder.
For example, if you have an upload speed of 1Mbps, you want to broadcast combined video and audio bitrates of about 800kbps (i.e. an audio bitrate of 192kbps and video of around 600kbps).
If your upload speed can support higher bitrates, we recommend an audio bitrate of 320kbps (for the best listening experience for your viewers) and up to 2,500kbps video for a 720p or 1080p broadcast. Higher video bitrates result in increased CPU usage on your streaming computer so if you notice a jumpy picture, stuttering or lag, try lowering the resolution or video bitrate.
In Chew Broadcaster, we have a number of pre-set output settings depending on what quality you'd like to broadcast. However, you can set your own bitrates in Broadcaster's Settings.
If you're using the 'Simple' Output mode in Settings, you can update video and audio bitrates in the same section:
If you're using the 'Advanced' Output mode in Settings, you'll need to update video and audio bitrates in their corresponding tabs:
