What is a Video File Extension?

A video file extension is a suffix at the end of a video file; every video file has a unique file format depending on which the file extension could be .mp4, .webm, .avi, .mov, .mkv, etc.

A video file format or extension stores video data digitally, containing audio and visual data, subtitles and other metadata required for video playback. MP4 (or MPEG-4 Part 14) is the most commonly used video file format that is compatible with almost every device or video player.
