About the AVI Format
AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows technology. It is one of the oldest video container formats still encountered today. AVI uses a straightforward structure where audio and video data are interleaved — stored in alternating chunks — allowing simultaneous playback of both streams. Its simplicity made it a dominant format throughout the 1990s and early 2000s.
While AVI benefits from broad legacy support and a simple, well-understood structure, it lacks many features expected in modern video formats. It has no native support for streaming over the internet, cannot embed modern subtitle formats or chapter markers, and its compression efficiency depends entirely on the codec used. AVI files also tend to be larger than equivalent MP4 or MKV files. The format is being gradually replaced by MP4 and MKV in virtually all use cases, though it still appears in older video archives and some legacy industrial systems.
