An AVI file is a widely used video format 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 video/audio codecs used, 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 is a video container you’ll still see often and ends with ".avi," with Audio Video Interleave referring to how it bundles audio and video, but because it’s just a container, the media formats inside determine whether it plays properly, which is why some .avi files stutter or go silent on unsupported devices; despite still showing up in legacy archives, camera exports, and DVR footage, AVI tends to be less efficient and less
universally compatible than MP4 or MKV.
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 compression inside, underscoring that AVI is only the container.
AVI is frequently described as a common format due to its origins in Microsoft’s old video framework, where it debuted as part of Video for Windows and became a standard for older cameras, recorders, editing software, and CCTV/DVR exports; its long legacy means most software can still open AVI today, though newer workflows generally favor MP4 or MKV for better consistency.

AVI file extraction kindly go to our web page. When people say "AVI isn’t the compression by itself," they mean that AVI acts only as a wrapper that stores media streams but doesn’t decide how they’re compressed—the actual shrinking is done by the codecs inside, which can differ dramatically from one AVI to another; this is why ".avi" alone doesn’t reveal whether the video uses DivX, Xvid, MJPEG, H.264, or another codec, nor whether the audio is MP3, AC3, PCM, etc., and why two AVIs can vary hugely in size, quality, and compatibility even though they look identical, leading to situations where a device "supports AVI" but not the particular codec combination inside, causing issues like missing audio or failure to play unless the right codec is present.
