An AVI file operates as a wrapper for encoded media with the term Audio Video Interleave describing the structure rather than the compression, which is defined by the codecs inside, so different .avi files can behave unpredictably when players can’t decode the embedded codecs, causing missing audio or stuttering; although it’s found in older exports, archives, and CCTV footage, it’s generally less efficient and less broadly compatible than modern formats like MP4 or MKV.
An AVI file serves as a standard older container with the .avi extension and a name meaning Audio Video Interleave, which reflects how the audio and video are stored together, but the compression varies based on whichever encoder is inside the container, causing some .avi files to play flawlessly and others to fail or play without sound; although AVI remains common in older downloads and CCTV or camera workflows, it’s generally less efficient and less reliable across devices than formats like MP4 or MKV.

An AVI file is simply a wrapper that holds audio and video and not a compression format, since “.avi” just signals Audio Video Interleave packaging, while the codec—such as Xvid, DivX, MJPEG, MP3, AC3, or PCM—determines compatibility and file size; this leads to differing behavior where one AVI works fine but another won’t open or has missing audio if the player doesn’t support the specific stream format, reinforcing the container-versus-codec distinction.
AVI is seen as a common video type thanks to its early widespread adoption, having been introduced in the Video for Windows era and becoming a default video container for many years—used by cameras, screen recorders, editors, and DVR systems—leading to broad support even now; still, modern workflows typically choose MP4 or MKV for their improved playback across current devices.
When people explain that “AVI isn’t the compression,” they mean AVI is just a container and doesn’t control how audio or video are actually compressed; that job belongs to the codec used inside, which may be DivX, Xvid, MJPEG, H.264 for video or MP3, AC3, PCM for audio, so two AVIs can behave entirely differently even though the extensions match, because a device might support AVI as a container but not the internal compression, leading to no-sound issues, refusal to play, or limited support outside of players like VLC.
