An AVI file stands as one of the older common video types 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 embedded stream types, which can lead to issues like silence or jerky playback; despite being common in legacy systems and camera/DVR outputs, AVI often produces larger files compared to formats like MP4 or MKV.
An AVI file appears often on Windows systems ending in “.avi,” with its name—Audio Video Interleave—indicating that audio and video are packaged together, but the real compression depends on whichever codec was used inside the container; this is why some .avi files work smoothly and others fail or lack sound when the device can’t decode the internal streams, and although AVI persists in older downloads and CCTV/camera outputs, it’s usually less efficient and less universally supported than MP4 or MKV.

An AVI file should be interpreted as a wrapper, not a codec because “.avi” only identifies the Audio Video Interleave container holding video and audio streams, while the codec inside—Xvid, DivX, MJPEG for video or MP3, AC3, PCM for audio—governs whether it plays smoothly or fails, which is why two AVIs can differ widely if a device can’t decode the internal codec, emphasizing that the container is separate from the compression method.
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 greater efficiency.
When people say “AVI isn’t the compression by itself,” they mean that AVI acts only as a wrapper that stores media streams but doesn’t decide how they’re compressed—the actual shrinking is done by the specific encoders, which can differ dramatically from one AVI to another; this is why “.avi” alone doesn’t reveal whether the video uses DivX, Xvid, MJPEG, H.264, or another codec, nor whether the audio is MP3, AC3, PCM, etc., and why two AVIs can vary hugely in size, quality, and compatibility even though they look identical, leading to situations where a device “supports AVI” but not the particular codec combination inside, causing issues like missing audio or failure to play unless the right codec is present.
