File Format
The container is a format used to bundle the video and audio data into one file. Common containers are MPEG-4, WebM and QuickTime.
Why do we test it?
In order to play the video, the browser or device must understand the container format to find out where the video and audio parts are located. MPEG-4 is supported by almost all browsers and devices. If you're serving the video in a different format, make sure your targeted device supports it. For example, serve videos in QuickTime formats only to Apple users.
