Description🔵 .avi (Audio Video Interleave) The .avi format is a multimedia container format introduced by Microsoft as part of its Video for Windows technology. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. While it supports various codecs for compressing video and audio data, the format has limitations like a lack of standardized aspect ratio and frame rate information. It's been largely superseded by more advanced formats like MPEG and MP, but is still used for its simplicity and wide compatibility with various media players and devices.
Technical details🔵 The `.avi` (Audio Video Interleave) format, created by Microsoft in 1992, is a multimedia container that synchronizes audio and video playback. It can house different codec combinations, which influence the video's quality and size. Typically, AVI files contain one audio and one video stream, and they depend on external codecs for compression, supporting both lossy and lossless types. This leads to variable file quality and sizes, usually larger than more efficiently compressed formats like MPEG or MOV. AVI's compatibility depends on the specific codecs used, which might not be pre-installed on all systems, potentially causing playback issues. The format has limited metadata capabilities and lacks support for Digital Rights Management (DRM), reducing its suitability for commercial use. Designed before the era of internet streaming, AVI is less apt for online use compared to formats like MP4. Its larger file size and limited features have contributed to its decline, with newer formats like MP4 and MKV becoming preferred for their efficiency and advanced capabilities.
