Video Encoder Settings

While switching to HTML5 is going to open our live streaming platforms to more people, one issue is the different video encoder settings some of our streamers use. As of June 26, 2017 you must use the following encoder settings in order for your stream to be viewed by everyone:

Minimum recommended settings:

  • 640×360 resolution
  • 500Kbps video bitrate (VBR can be used although CBR is preferred)
  • 128Kbps audio bitrate
  • 30fps
  • Keyframe interval of 2.0 (or 250 depending on the encoder software you use)
  • H.264/x264 video codec
  • AAC or MP3 audio codec

Maximum recommended settings:

  • 1920×1080 resolution
  • 3500Kbps video bitrate CBR
  • 128Kbps audio bitrate
  • 60fps
  • Keyframe interval of 1.0 (or 60 depending on the encoder software you use)
  • H.264/x264 video codec
  • AAC audio codec

Note: The current version of MvnCaster does not meet the minimum requirements which will greatly limit your audience. MvnCaster will be removed from Breakers.TV,, and Pearl TIme on June 26, 2017. It will still be available on Vaughn Live but is not recommended until the new MvnCaster has been built.

(MvnCaster is the built in broadcast tool)

Also note: To ensure the lowest latency, set your keyframe interval low. We allow keyframe intervals as low as 0.5 (30), however be mindful of playback issues of your viewers with poor internet connections.


  1. I am Already using HTML5 To Cast OBS don’t Use Flash but your music Channels are not going to like the 128kbps there is a big difference between 320 & 128 i know, i work in Radio we use Flac files on Air for a reason, And MP3 is going away anyway It is old Technology.
