This article explains what an AV file is, how to use it on your computer, and how to convert it to another file format, such as MP4.

Some files that use the AV file extension are documents created by Final Draft AV version 1. Later editions create documents with the .XAV file extension instead. Template files use the similar XAVT file format.

Final Draft AV is a word processing program that simplifies the process of adding dialogue, scenes, character information, and other things needed for a script. AV files are used by the program to store this information.

If your AV file is not a document, it is most likely a video. Some cameras use this file extension to store video data.
