AVI (Audio Video Interleave)

AVI is a popular media container developed and maintained by Microsoft. The AVI format first appeared in November 1992, becoming the main format for storing the video in Microsoft Windows operating systems. The AVI file format can contain video and audio data compressed using different combinations of codecs. The AVI file itself does not indicate which codecs it uses, so AVI video can be packed with a lot of different codecs, which means that not all AVI can be played on your device without additional programs.
