| Description | MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. | Audio Video Interleaved (also Audio Video Interleave), known by its initials AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows software. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. |
| Technical details | Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. | AVI is a derivative of the Resource Interchange File Format (RIFF), which divides a file's data into blocks, or 'chunks.' A FourCC tag identifies each 'chunk'. An AVI file takes the form of a single chunk in a RIFF formatted file, which is then subdivided into two mandatory 'chunks' and one optional 'chunk'. |
