An AVI file is essentially a box holding encoded media with the name meaning Audio Video Interleave, and the real compression depends on the codecs stored inside, so two .avi files may act differently if your device can’t handle the specific codecs, which explains issues like no sound or choppy playback; it remains common in older exports, legacy archives, and DVR footage, although modern formats like MP4 or MKV usually provide broader compatibility.
An AVI file is a container many computers still recognize and uses the .avi extension, standing for Audio Video Interleave, meaning it packages audio and video together but leaves compression to the encoding tool inside; this leads to varied playback results when devices support AVI but not the internal streams, and although AVI remains present in older downloads and camera or CCTV exports, more modern containers like MP4 or MKV usually perform 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 called a common video format due to its long lifespan 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 only organizes audio/video without defining the compression method, leaving that to the specific compression algorithm inside, which can vary from DivX/Xvid to MJPEG or H.264 for video and MP3/AC3/PCM for audio; this is why two AVI files can differ massively in size, quality, and compatibility, with devices supporting AVI only in cases where they also support the internal codec setup, which explains why some AVIs play fine while others show video without sound or fail on smart TVs.
