An AVI file is a long-used video container 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 is an older but common video type 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 encoding format 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 serves as a container for encoded media instead of defining compression itself, and the ".avi" extension simply indicates Audio Video Interleave packaging, while the codec—like Xvid, DivX, MJPEG, MP3, AC3, or PCM—controls compatibility and size; this is why one AVI may play everywhere while another stutters or has no audio if the device doesn’t support the encoded stream type, underscoring that AVI is only the container.

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 more modern compatibility.

When people say "AVI isn’t the compression," they mean AVI acts as a storage wrapper 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 specific media formats used, which explains why some AVIs play fine while others show video without sound or fail on smart TVs.
