What Is an AVI File?
AVI is Microsoft's video container from the Windows 3.1 era. Old camcorders, DVD players with DivX and many archives still use it. AVI is a container rather than a compression method — container, typically MPEG-4 (Xvid/DivX) video with MP3 audio. What is inside decides the quality.
