An AVI file serves as a familiar container type where AVI stands for Audio Video Interleave, meaning it bundles audio and video together but isn’t the compression method itself—the codecs inside determine how the media is encoded, so two .avi files can behave very differently depending on the specific compression formats inside, which is why some play fine while others stutter or lose sound; AVI persists in older downloads, archives, camera exports, and CCTV footage because it’s been around since early Windows, though compared to modern formats like MP4 or MKV it often creates larger files.
An AVI file is a long-used video format with the .avi extension and a name meaning Audio Video Interleave, which reflects how the audio and video are stored together, but the compression varies based on whichever encoder is inside the container, causing some .avi files to play flawlessly and others to fail or play without sound; although AVI remains common in older downloads and CCTV or camera workflows, it’s generally less efficient and less reliable across devices than formats like MP4 or MKV.

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 specific stream format, reinforcing the container-versus-codec distinction.
AVI is widely described as a common video format since it dates back to early Windows days and became deeply integrated into the Windows environment; Microsoft introduced it during the Video for Windows period, and over time older cameras, screen recorders, editing tools, and many DVR systems used it as a standard output, which is why so many programs still recognize AVI and why it appears in older downloads and archives, even though today MP4 or MKV are often preferred for their better efficiency.
When people say “AVI isn’t the compression,” they mean AVI is only the container, not the codec, with the real compression determined by the format actually used—DivX, Xvid, MJPEG, H.264 for video or MP3, AC3, PCM for audio—so two .avi files can look identical but differ hugely in size and compatibility because your device may support AVI but not the particular internal codec, leading to problems like silent video, refusal to open, or playback depending on apps like VLC that include more decoders.
