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 audio/video encoding, which can lead to issues like silence or jerky playback; despite being common in legacy systems and camera/DVR outputs, AVI often performs less efficiently compared to formats like MP4 or MKV.
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 codec 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 works as a wrapper rather than a codec rather than a specific compression method, with “.avi” indicating an Audio Video Interleave wrapper that bundles audio and video streams together, while the real factor behind size and compatibility is the specific audio/video encoder, such as Xvid, DivX, MJPEG, MP3, AC3, or PCM, which is why two AVIs can behave very differently—some play everywhere, others lose sound or fail on phones or TVs when the needed codec isn’t supported, reinforcing the idea that AVI is just the box and the codec is what’s inside it.
AVI is often called a common video format because it’s been around for ages 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 greater efficiency.
When people say “AVI isn’t the compression,” they mean AVI defines structure, not compression, with the real compression determined by the codec inside—DivX, Xvid, MJPEG, H.
