An AVI file is a format known for bundling streams together under the name Audio Video Interleave, but the compression inside depends on the chosen codecs, so .avi files can vary in behavior because playback success relies on whether your device supports the embedded codecs, explaining no-sound or jittery playback issues; it still shows up in legacy material and DVR footage, even though newer formats like MP4 or MKV offer more stable compatibility.

An AVI file is a long-standing PC video type 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 acts as a container for multiple media streams 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 often called a common video format thanks to its early and long-standing presence in the Windows ecosystem, having been introduced during Microsoft’s Video for Windows era, which made it a default choice for storing and sharing video on PCs; that historical momentum meant older cameras, screen recorders, editors, and many CCTV/DVR systems adopted it, so plenty of software still opens AVI files today, and you’ll see them in older downloads and archived collections, even though newer workflows often prefer MP4 or MKV for their better consistency.
When people say “AVI isn’t the compression,” they mean AVI works only as a container and does not compress anything by itself—the compression is handled by the chosen compression formats, which can range from DivX, Xvid, MJPEG, H.264 to MP3, AC3, PCM; this variation causes two AVIs to behave differently even if their extensions match, because a player may support AVI containers but not the internal media encoding, resulting in missing audio, failure to open, or playback working only in apps like VLC.
