AVI, short for Audio Video Interleave, is a multimedia container format developed by Microsoft. It is widely used for storing audio and video data in a single file, allowing synchronized playback of both media types.
AVI files utilize the Resource Interchange File Format (RIFF) to store data chunks, which can include audio, video, and even text. The format supports various codecs, allowing for high-quality compression and decompression of multimedia content.
AVI files can be played on most media players and are compatible with multiple operating systems. However, due to its relatively large file size, AVI is gradually being replaced by more efficient video formats like MP4.
