According to the definition from Wikipedia, M4V is a video container format, which is developed by Apple Inc. M4V file format is used to encode video files in iTunes Store, and thus protected by Apple's FairPlay copy technology. It allows users to play iTunes movies, TV shows and music videos, etc. on Apple device only, such as iTunes, iPhone, iPad, etc., in order to prevent piracy and copy. This, on the other hand, restricts users from watching iTunes videos on other devices like Andorid phones, Windows phones, etc., even if they purchased or rented them.

What Is MP4?

Short for MPEG-4 Part 14, MP4 is considered as the most commonly used multimedia container format. Developed by Moving Picture Experts Group (MPEG), it can be used to store not only video and audio, but also images, subtitles and other data. Thanks to its good compatibility and compression, MP4 allows streaming over the Internet and playing on almost all media players and devices.
