The file you upload will be played directly. No re-encoding like popular video sites do for you. That means:

  • Container: MP4 (popular) or WebM (patent-free)
  • Video: H.264 (MP4); VP8, VP9 (WebM)
  • Audio: AAC, MP3 (MP4); Opus, Vorbis (WebM)

Not a complete list, but those are your best bets right now.

Chrome and Brave wouldnt work for me. They crash after the upload starts. Firefox seems to be working, but its taking forever. At least it hasn't crashed yet!

mp4 h264 works for me.
