The MP4 file format is used for storing audio and video data. MP4 files use the MPEG-4 video compression method developed by the Moving Picture Experts Group. MP4 is short for MPEG4.

These files are often used for storing and transferring movies over the internet. They’re seen as the upgraded MP3s and are supported by iPods, Zune and a wide range of multimedia players.

Besides audio and video data, MP4 files can also contain text (for subtitles for example) and still images. Video compression is done through MPEG-4 encoding and the audio track is processed using Advanced Audio Coding (AAC).
