About the formats
About MP4
MP4 is the most widely supported video container, normally holding H.264 video alongside AAC audio. It is normally used for video for the web, phones, editing software and social platforms. It is a container rather than a codec, so an MP4 can still hold streams a given player cannot decode.
About WebM
WebM is an open, royalty-free video container built for the web, typically carrying VP8 or VP9 video with Vorbis or Opus audio. It is normally used for video embedded directly in web pages. Editing software and older devices support it less consistently than MP4.
What to expect
- Up to 5 minutes and 1080p.
