| File Description | M4V is a popular video container format developed by Apple and used by its iTunes application for saving TV episodes, movies, and music videos. It's similar to a .MP4 file, but may be protected using Apple's FairPlay DRM copyright protection and has a different treatment of AC3 (Dolby Digital). To play a DRM protected M4V file, your computer must be authorized with the account you purchase the video, or remove the DRM with DRM removal software and the account. To play unprotected M4V files, just find a video player that supports M4V format, or simply change the file extension from ".m4v" to ".mp4" which is supported by most video players. |
