DescriptionIntroduced by Microsoft in 1992, the .avi (Audio Video Interleave) format is a multimedia container designed for simultaneous audio and video playback. AVI files support various audio and video encoding methods, or "codecs." These codecs significantly affect both the quality and file size of the video.
Technical detailsTypically, AVI files contain a single audio track and a single video track. File compression relies on external software called "codecs." These codecs can either preserve all original data ("lossless") or discard some data to reduce file size ("lossy"). Consequently, AVI files can vary greatly in quality and size, often resulting in larger files than other formats like MPEG or MOV. These other formats generally use more efficient compression techniques, making them a better choice for space-saving.
