An AVI file serves as a classic Windows-era container where Audio Video Interleave describes how audio and video are bundled, but not how they’re compressed, since the actual codecs decide that—meaning two .avi files can differ wildly depending on the audio/video formats, leading to playback problems if a player lacks support; its longevity keeps it alive in older downloads, camera outputs, and CCTV systems, though it’s generally less efficient and less consistent across devices than formats like MP4 or MKV.
An AVI file is a widely seen video format ending in “.avi,” with its name—Audio Video Interleave—indicating that audio and video are packaged together, but the real compression depends on whichever encoder 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 serves as a box for packed media 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 internal compression, reinforcing the container-versus-codec distinction.
AVI is considered a common video format primarily because of its long legacy, having originated in Microsoft’s Video for Windows era and becoming a go-to container for many years; that led older cameras, recorders, editors, and even CCTV/DVR exporters to rely on it, leaving a huge trail of AVI files that software still supports today, though modern workflows favor MP4 or MKV for more predictable compatibility.
When people say “AVI isn’t the compression by itself,” they mean that AVI works purely as a container that stores media streams but doesn’t decide how they’re compressed—the actual shrinking is done by the internal compression methods, 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.
