The M4V file format is a video container format developed by Apple and very similar to the MP4 format. The main difference is that M4V files can be optionally protected by DRM copy protection.
Apple uses M4V to encode video files in the iTunes Store. Unauthorized copying of M4V files can be prevented using Apple's copy of FairPlay copy. FairPlay protected M4V files can only be played on authorized computers (using iTunes) with the account used to purchase videos. In QuickTime, M4V video using FairPlay DRM is identified as "AVC0 Media".
In addition to Apple iTunes and Apple QuickTime Player, M4V files can also be opened and played with Media Player Classic, K-Multimedia Player, RealPlayer, Zoom Player, VLC media player, MPlayer, DivX Plus Player, and Nero Showtime (included with Nero Multimedia Series). Non-DRM format can also be played in the webOS Video Player for use on Palm Pre smartphone, Palm Pixi. It can also be played by the Android operating system with its video player. It is used as the default video conversion format for HandBrake and Air Video Server on Macintosh. Some other video players can also recognize and play M4V files if the file extension is changed from ".m4v" to ".mp4".
M4V files produced with hand brakes can also be played on the PlayStation 3, with full Dolby Digital 5.1 surround support.
