Description

AVI basically stands for Audio and Video Interleave, it has an extension written as .avi and users use this very format to store audio and video on their PC which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by storing video and audio into a single file, the simple architecture of .avi format allows it to run on various operating systems such as Windows, Mac, Linux, Unix and it is also supported by various web players as well.

Technical details

AVI format uses the support of Resource Interchange File Format (RIFF) where the whole data is stored into chunks and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag and it can decode the chunk containing metadata for the video and the second chunk gets recognized by the movi tag and it contains the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.
