- Multimedia format used by digital audio and video programs; contains captured audio and video data as well as metadata that describes the media stored in the file; designed by Society of Motion Picture and Television Engineers (SMPTE) as a standard container for audio and video data; can be converted into other formats, such as .AVI or .MOV.
