Part 1. M4V and MP4 Explained

What is M4V?

Developed by Apple, M4V is a common container format used when purchasing or renting movies, TV shows, and music videos from the iTunes Store. The primary reason for creating it was to prevent unauthorized distribution of the videos. Therefore, M4V files such as iTunes movies or iTunes music videos are protected with Apple's FairPlay DRM (Digital Rights Management). This is also a major difference between M4V and MP4, but more about that later.

What is MP4?

MP4, the abbreviation for MPEG-4 Part 14, is also a container format that can wrap multimedia data such as video, audio, and even subtitles and images. An MP4 file doesn't feature with any DRM protection and therefore MP4 is a universally-used format that is compatible with most media players like Windows Media Player, VLC player, and devices such as Android and Windows Phone.

Part 3. M4V vs MP4: Which Is the Best?

M4V vs MP4 comparison

There is no saying which video format is better. Like I've mentioned above, M4V is the same as MP4 with optional DRM protection. If a video isn't encrypted, there isn't any real difference. M4V is basically Apple's version to flag it as a video file and attach it to iTunes. It may be embedded with video ID3 style tags. Except that, choosing which video format is according to your preferences and needs.

If you are using Apple Products or you are an Apple addict…

M4V is better suited for Apple devices to store digital information. Reserving the M4V extension can ensure your video contents are protected so that they cannot be copied or edited.

Also, storing video files in M4V extension enables certain features such as AC3, chapters, and soft subs to work smoothly. For instance, Apple TV needs the M4V file extension to know how to deal with the AC3 audio track in the MP4 container. Besides, if you change the extension of a file containing AC3 from M4V to MP4, the file won't be played on an iPhone or iPad.

If you are using non-Apple devices…

MP4 proves to be a much better option. MP4 essentially enjoys better compatibility cross-platform than M4V. It has been widely accepted for a really long time as it is user-friendly to copy, transfer, and playback on many platforms including Android and Windows. Besides, even if an MP4 file is corrupted, it is easy to fix your inaccessible videos using some video repair software.

Q: How to play M4V files?
