Audio/Video Glossary - AVIAudio Video Interleaved. A computer video/graphics format. This format interleaves digitized video frames (or computer-generated frames) and synchronized audio in one file. The clips generated in the AVI format may be played back in a Windows® equipped PC, usually independent of screen resolution and color palette. This also denotes a practically uncompressed file format obtained for example in a PC, when digital or analog video and audio are captured from an external source. As it is uncompressed, it can occupy up to 200 MB of disk space for every minute of captured video.
