MP4

A .MP4 file is a multimedia file mostly used to store a movie or a video clip. It can also contain subtitles and images. MP4 is short for MPEG-4 Part 14, based on the QuickTime File Format used by MOV and QT files.

MP4 files use the MPEG-4 compression, a standard developed by the Moving Picture Experts Group. It includes separate composition for audios and videos.
