What is Audio Video Interleave (AVI)?

Audio Video Interleave, better known as AVI, is a multimedia format that was the first audio/visual format created for Windows, allowing for both audio and video and synchronous audio/video playback. In fact, the “interleave” in audio video interleave refers to AVI’s ability to intermix chunks of video and audio data, in an alternating series.

Based on the Resource Interchange File Format (RIFF), the AVI is considered a container format, in that it can contain different types of data and allows for encoding and decoding by different methods (including Cinepak, DivX, DV, Editable MPEG, Motion JPEG, QPEG and Xvid).

The AVI format was first introduced in 1992, and developments in audio/video technology since its inception has exposed some limitations in AVI’s core features. Nevertheless, AVI is still a recognized format, especially on Windows players.
