What is AVI file format?

Audio Video Interleave, known by its acronym AVI. But what is an AVI file exactly? AVI file format is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI file format can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI file format support multiple streaming audio and video, although these features are seldom used. Most AVI files also use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called "AVI 2.0".

There is slight overhead when used with popular MPEG-4 codecs (Xvid and DivX, for example), increasing file size more than necessary. The AVI container has no native support for modern MPEG-4 features like B-Frames. Hacks are sometimes used to enable modern MPEG-4 features and subtitles, however, this is the source of playback incompatibilities.

AVI file format do not contain pixel aspect ratio information. Microsoft confirms that "many players, including Windows Media Player, render all AVI files with square pixels. Therefore, the frame appears stretched or squeezed horizontally when the file is played back." There are other video container formats that allow irregular shaped pixels.
