AVI File Format

AVI Video category

AVI is Microsoft’s classic video container from the 90s. Files are large by modern standards but old devices and software still produce them.

Typical use: Some legacy systems and DVR/camera devices only accept AVI input.

About the AVI format

AVI (Microsoft, 1992) is one of the oldest video containers still encountered. It has no native understanding of modern features — variable frame rates, modern codecs, subtitles, chapters — and stores everything through a 32-bit indexing system that caps reliable file sizes around 2 GB (OpenDML extensions patched some of this). Most AVIs you meet today are DivX/Xvid-era rips or old capture-card output.

There is no reason to produce AVI today; the realistic task is converting old libraries into MP4, which typically cuts file size by half or more at equal or better quality.
