MP4 (MPEG-4) file

MP4, MPEG4, or MPEG-4 is an audio and video compression standard. It was introduced in 1998 and agreed upon as a standard by the MPEG (Moving Picture Experts Group) shortly after.

MPEG-4, like the MPEG-1 and MPEG-2 standards, codifies methods for encoding audio and video while optimizing media fidelity and reducing file size as much as possible. It includes features for 3D rendering with VRML (Virtual Reality Modeling Language), DRM (digital rights management) support, and various forms of interactivity. Codecs and technologies which use the MPEG-4 standard include DivX, Xvid, QuickTime, DVDs, and Blu-ray discs.

Audiobooks and podcasts often use the MP4 format, as do ringtones on the iPhone. Other mobile phones use a variation of the MP4 format, called 3GP.
