Description | 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. | DivX 6 expanded the scope of DivX from including just a codec and a player by adding an optional media container format called 'DivX Media Format' ('DMF') (with a .divx extension) that includes support for the following DVD-Video and VOB container like features. This media container format is used for the MPEG-4 Part 2 codec. This new DivX Media Format also came with a DivX Ultra Certified profile, and all Ultra certified players must support all DivX Media Format features. While video encoded with the DivX codec is a MPEG-4 video stream, the DivX Media Format is analogous to media container formats such as Apple's QuickTime. In much the same way that media formats such as DVD specify MPEG-2 video as part of their specification, the DivX Media Format specifies MPEG-4-compatible video. However, despite using the '.divx' extension, this format is an extension to the AVI file format. |
Technical details | 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'. | |
