M4V File Extension

The M4V data format is a video file format developed byApple, which is very close to the MP4 format. The differences includethe optional Apple's DRM copyright protection, and the treatment of AC3(Dolby Digital) audio, which is not standardized for that MP4 container.Apple uses the M4V files to encode TV episodes, movies, and musicvideos in the iTunes Store. Making use of Apple’s FairPlay DRM copyrightprotection could protect the copyright of M4V files. To play aprotected M4V file, the pc needs to be authorized (using iTunes) withthe account that has been used to pick the video. However, unprotectedM4V files without AC3 audio might be recognized and played by othervideo players by changing the file extension from ".m4v" to ".mp4".Under QuickTime, M4V video with FairPlay attached with it is recognizedas AVC Media.

To play a protected M4V file, your personal machine must beauthorized (using iTunes) with all the account, which was used to choosethe video. Unprotected M4V files could be recognized and played byother video players by changing the file extension from ".m4v" to".mp4."
