WebM plays in Chrome. Not everywhere else.

Chrome, Meet and a lot of screen recorders save WebM (VP8/VP9/AV1). iPhone, Final Cut and Discord still prefer MP4.

This is almost always a transcode. VP9 inside WebM cannot be remuxed into MP4. The hardware encoder writes H.264.

Audio is usually Opus in WebM; we map it to AAC in the MP4 so Apple devices play sound.
