AVI File Converter

AVI files use a chunk-based structure defined by the Resource Interchange File Format (RIFF), which segments data into different blocks for video, audio, and metadata. Typically, AVI supports uncompressed video or video compressed with codecs like DivX and Xvid. The format does not inherently support modern features like subtitles or variable frame rate, which newer formats provide.

AVI files can contain video and audio encoded in a variety of codecs, which can affect compatibility and file size. Despite newer formats like MP4 gaining popularity, AVI remains favored for its simplicity and minimal compression. Interestingly, the 'interleave' part of its name refers to how audio and video data are stored alternately to facilitate synchronized playback.
