Choose live encoder settings, bitrates, and resolutions

It's important to make sure your live stream is high quality. Make sure you choose a quality that will result in a reliable stream based on your internet connection. We recommend running a speed test to test your upload bitrate.
 

If you're streaming in the Live Control Room, you only have to specify your resolution, frame rate, and bitrate in your encoder. YouTube will automatically detect which encoder settings you chose.

 

YouTube will automatically transcode your live stream to create many different output formats so that all of your viewers across many devices and networks can watch.

 

Make sure to test before you start your live stream. Tests should include audio and movement in the video similar to what you'll be doing in the stream. During the event, monitor the stream health and review messages.

Note: For 4K / 2160, the option to improve for low latency is not available. All streams will be optimized for quality and set to normal latency.

Stream resolution detection with custom stream keys in Live Control Room

By default (recommended), YouTube will automatically detect your resolution and frame rate. If you want to manually select a resolution, create a custom key and choose “Turn on manual settings" under “Stream Resolution."

Recommended bitrate setting ranges are based on video ingestion codec, video ingestion resolution and frame rate.

Notes:
  • We recommend streaming to YouTube Live with RTMPS, a secure extension to the popular RTMP streaming video protocol. Your data will be encrypted all the way into and through Google's servers, so nobody can intercept your communication with the service. Learn more.
  • If you want to stream in HDR, we recommend using H.265 over RTMP(S). If your encoder does not yet support these capabilities with RTMP, you may consider using HLS (HTTP Live Streaming). Learn more.
  • Live streams are automatically available on game consoles and mobile devices via the YouTube app and m.youtube.com.
