An AVI file acts as a wrapper that holds audio and video under the name Audio Video Interleave, but the compression inside depends on the chosen codecs, so .avi files can vary in behavior because playback success relies on whether your device supports the specific audio/video encoders, explaining no-sound or jittery playback issues; it still shows up in legacy material and DVR footage, even though newer formats like MP4 or MKV compress more efficiently.
An AVI file is one of the older common video formats and uses the .avi extension, standing for Audio Video Interleave, meaning it packages audio and video together but leaves compression to the compression format 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 is a container format rather than a codec 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 proper media support, highlighting that the container itself isn’t the compression method.
AVI is often labeled a common video format due to its deep integration with early PCs, introduced by Microsoft during the Video for Windows era and becoming a default way to store and share PC video; older recording tools, cameras, editors, and DVRs embraced it, which is why AVI files still show up in downloads and archives, although modern setups tend to choose MP4 or MKV for their higher
efficiency.
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 If you beloved this information in addition to you desire to acquire more information regarding
