What Is an AV File?
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 processor program that simplifies the process of adding dialogue, scenes, character information, and other things necessary for a script. AV files are used by the program to store this information. If your AV file isn’t a document, it’s most likely a video. Some cameras use this file extension for storing video data.
How to Open an AV File
Final Draft AV, a scriptwriting software program for Windows and macOS, is used to open XAV and AV files that are document files. Since they’re based on the XML format and are therefore plain text files, you can also open XAV and AV files with a text editor. The only software we know that might support video files that use the .AV file extension is Yoosee. However, given that it’s not a popular file extension for videos, it’s possible you can just rename the file to something more common like, MP4 or AVI and then open it with VLC. This will only work if the AV file is technically an MP4, AVI, etc., but is using the AV file extension.
How to Convert an AV File
Final Draft AV can convert a document to similar and more popular formats like PDF, RTF, TXT, FCV, XAV, and XAVT, through the File > Save As menu. Yoosee, linked above, should be able to convert from AV to MP4. From there, you can use a free video converter to save the MP4 to another preferred video format.
Still Can’t Open the File?
If your file still won’t open even after trying the suggestions above, then you’re probably not dealing with a Final Draft document or a video. You might be misreading the file extension, which is remarkably easy to do, especially with two-letter extensions. For example, AVI, AVHD, AVS, and AVE look similar to AV, but that doesn’t necessarily mean the formats have anything to do with each other. You might get an error if you open one of those files with an AV file opener, and vice versa. MAV is another to watch out for. This could easily be confused for an AV file. You need Microsoft Access to open it.
