An AVI file serves as a familiar wrapper format where Audio Video Interleave refers to how the media streams are packaged, and the actual compression depends on the internal codecs, meaning two .avi files may play differently depending on the codec support, which can lead to issues like silence or jerky playback; despite being common in legacy systems and camera/DVR outputs, AVI often works inconsistently across newer devices compared to formats like MP4 or MKV.
An AVI file is a traditional Windows video container identified by “.avi,” where Audio Video Interleave simply means the audio and video are bundled together, yet AVI itself doesn’t define how they’re compressed—the codec inside does, which leads to playability differences if the player can’t decode the internal streams; while AVI still appears in legacy archives, downloaded videos, and camera or DVR exports, newer formats like MP4 and MKV typically compress better.
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 embedded codec, reinforcing the container-versus-codec distinction.
AVI is often labeled a common video format because of its long-standing role in Windows, introduced by Microsoft during the Video for Windows era and becoming a default way to store and share PC video; older recording tools, cameras, editors, and DVRs embraced it, which is why AVI files still show up in downloads and archives, although modern setups tend to choose MP4 or MKV for their more uniform compatibility.
When people say “AVI isn’t the compression,” they mean AVI stores tracks without defining compression, while the internal encoding method is what determines quality, size, and compatibility; since those codecs can be DivX, Xvid, MJPEG, H.
