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 internal encoding choices, 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 tends to be less efficient.
An AVI file acts as a familiar wrapper for video and audio 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 media format 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 should be thought of as a box, not the contents where “.avi” marks an Audio Video Interleave file holding audio and video streams, and the codec inside—Xvid, DivX, MJPEG for video or MP3, AC3, PCM for audio—dictates how well it plays, which explains why two .avi files can behave differently if a device lacks the correct codec, highlighting that the container itself isn’t the compression method.
AVI is seen as a common video type mostly because of its long Windows heritage, having been introduced in the Video for Windows era and becoming a default video container for many years—used by cameras, screen recorders, editors, and DVR systems—leading to broad support even now; still, modern workflows typically choose MP4 or MKV for their improved playback across current devices.

When people say “AVI isn’t the compression,” they mean AVI only organizes audio/video without defining the compression method, leaving that to the codec 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 exact encoding combination, which explains why some AVIs play fine while others show video without sound or fail on smart TVs.
