AVI history

The AVI (short for Audio Video Interleave) first saw the light of day in 1992, when it was released as part of the Video for Windows (VfW) project. The aim of this project was to add digital video playback to the Windows operating system. It was first released as an add-on for Windows 3.1 and since then has become a bundled part of every new Windows distribution.

The role of the AVI was to be the file container for this new framework. In the beginning, video clips were of small resolution and quality (320 x 240 pixels and with a maximum of 30 frames per second). With the development of the Video for Windows framework, the AVI file format was also updated and by 1996, AVI files were using a new file format extension developed by the Maxtor OpenDML group, which is unofficially known as AVI 2.0.
