Part 1: What is an M4V Video File

M4V, like MP4, is an Apple video format that can be DRM protected, limiting its use to Apple devices and software like iTunes and iOS devices.

Made for Apple devices, M4V uses the .m4v extension for efficient video delivery. It supports H.264 video compression, AAC, and Dolby Digital audio codecs, ideal for storing iTunes movies and TV shows.

While playable on Apple devices, M4V files may not work on non-Apple devices, especially if DRM protected. Yet, DRM-free M4V files can often be used on other platforms by changing the file extension to .mp4.
