Library or "bin" of media files created by Avid Media Composer, a professional video editing application; bundles media files in a single location so that they can be organized and managed more easily; allows multiple versions of input files (e.g., English and Spanish audio) to be stored simultaneously.

AVV files use the AS-02 standard, which is a media storage format that allows multi-version mastering of videos. The AS-02 standard was developed by the Advanced Media Workflow Association (AMWA).
