What WEBM and MP4 files are
WEBM
WebM is an open, royalty-free video format backed by Google and built for the web. It pairs VP8, VP9 or AV1 video with Vorbis or Opus audio in a container based on Matroska, and it plays in modern browsers, though video editors support it less widely than MP4.
MP4
MP4 is the most common video container, holding video, audio and subtitles in one file. It balances quality and file size well and plays on phones, browsers, TVs and editing software alike.
