The MP4 file format and the .mp4 filename extension refer to the MPEG-4 part 14 digital multimedia format developed by the Moving Picture Experts Group. It is used as a multimedia container to wrap encoded digital video and audio streams, including subtitles and still images if required. In recent decades, the format has been popularized as one of the main standards for streaming media over the internet and other computer networks and for the digital distribution of large multimedia files. MP4 supports a large number of compression audio codecs allowing files in this format to maintain a relatively small size without discounting playback quality.
Being the most broadly compatible audio and video container format from the lossy class of containers, the MPEG standards are supported by numerous audio and video products and software applications. The standards were designed to meet the growing need for digital storage of audio and video media. They both utilize a lossy compression to scale down VHS quality digital video and CD audio. The two formats, mpeg-1 and mpeg-2, are the result of the combined efforts of the moving picture experts group which was established in 1988. The mpeg-1 has its beginnings in the same year, with an initial release to public in 1993.

The MPEG-4 Part 14 is standardized as part of the MPEG-4 format in ISO/IEC 14496-14:2003. It is recognized as a container format for audio and video streams and references several filename extensions of which .mp4 is one. The MPEG-4 Part 14 is in many ways identical to Apple's QuickTime format which formed the basis of MPEG-4. However, there are slight differences in compatibility with other previously standardized MPEG features and the added support for IOD or initial object descriptors which describe elementary data streams and set profile information of the resources needed for content playback.
The mpeg-1 file format extension is standardized in ISO/IEC 11172. It was extended from the H.261 and JPEG file formats and is capable of scaling down VHS video at a ratio of 26:1 and CD audio at a ratio of 6:1. The format allows for transcoding of video and associated audio to a maximum bitrate of 1.5 Mbit/second. interlaced video is supported in the second iteration of the mpeg format, mpeg-2. Video encoding is achieved using the compression standard H.262. The newer format also has added support for newer audio encoding techniques.
