The M4V data format is a video file format developed by Apple, which is very close to the MP4 format. The differences include the 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 music videos in the iTunes Store. Making use of Apple's fairplay review DRM copyright protection could protect the copyright of M4V files. To play a protected M4V file, the pc needs to be authorized (using iTunes) with the account that has been used to pick the video. However, unprotected M4V files without AC3 audio might be recognized and played by other video players by changing the file extension from ".m4v" to ".mp4". Under QuickTime, M4V video with FairPlay attached with it is recognized as AVC Media.

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