VidiU encoder settings for streaming to Facebook Live
Last Updated 3 years ago

Facebook Live has strict requirements for the encoded audio and video settings.

These encoding settings are subject to change, but the current limits are listed on this page:

As of March 2018, Facebook will officially accept the following maximum settings:

  • Video resolution: 1280x720
  • Video bitrate: 4 Mbps (4000 kbps)
  • Frame rate: 30 frames per second (fps)
  • Audio bitrate: 128 kbps

Preset Settings

For convenience, you can use the following preset options with the built-in Facebook integration on the VidiU or VidiU Pro:

  • Video Quality: HD (1280x720 resolution, 2 Mbps video bitrate)
  • Frame rate: Full*
  • Audio Quality: Medium (128 kbps audio bitate)
* For an explanation of how the frame rate settings are affected by the video input resolution, refer to this article. Refer to the most recent version of the VidiU Reference Guide for full details on these settings, found in this section.

Custom Settings

If you're choosing custom settings, make sure that the video resolution, video bitrate, audio bitrate and frame rate all are within Facebook's guidelines.

Configuration Notes:

1) the Continuous Live Streaming option is Disabled as the default setting. Do not change this setting unless you have read Facebook's documentation on Continuous Live Streams and how this can affect your stream -- no Video on Demand is saved for later playback, no notifications are sent to followers, and no metrics are collected, as described in this article:

2) do not choose the "Full HD" video setting which corresponds to 1920x1080 resolution and a 5 Mbps video bitrate, or higher than Medium for the Audio Quality. If choosing a Custom video resolution, video bitrate, or audio bitrate do not select options that are different from Facebook's published guidelines.

Choosing video resolution or video bitrate values that are higher than Facebook's maximum published settings, or audio bitrate values which are higher or lower than Facebook's setting of 128 kbps could cause issues with stream quality or stability.
