What is M4V (iTunes Video)?
M4V is Apple's video format used by iTunes for purchased and rented movies and TV shows. It is based on the MP4 container with Apple's FairPlay DRM protection.
M4V files are essentially MP4 files - the only difference is that DRM-protected M4V files can only be played on Apple devices and iTunes. DRM-free M4V files are functionally identical to MP4.
How M4V Relates to MP4
M4V uses the same ISO Base Media File Format underlying MP4, the structure standardized as ISO/IEC 14496-14.[1] Apple introduced the distinct .m4v extension primarily to associate the files with iTunes and to signal the possible presence of FairPlay DRM, but the internal box structure is essentially that of MP4.[2] Renaming a DRM-free M4V to .mp4 typically lets standard players open it unchanged.[3]
Codecs and DRM
M4V files commonly carry H.264 video with AAC audio, the same codec pairing used throughout the MP4 ecosystem.[4] Apple's FairPlay copy protection, when applied, encrypts the media so it can only be decrypted on authorized Apple devices and iTunes accounts, which is the practical distinction between a protected M4V and an ordinary MP4.[2]
