RELATED: How to Remove DRM From iTunes Movies and TV Shows Assuming it doesnвЂ™t have any DRM associated with it, letвЂ™s look at how you can open one up.

You should see a submenu listing all of the other installed apps that your Mac thinks might be able to open the file. From the shortcut menu that opens, choose Open With. I understand that I will probably need to get or buy an app from the App Store, but would welcome your advice on any specific ones to get. For interest, I can view the files on my iMac. To open a DRM protected M4V file, your computer-or device- must be authorized using iTunes and the AppleID that was used to purchase/rent the video. Control-click (or right-click) the file in the Finder. Whenever someone sends me an email with a MP4 file attached, I can see that there is an attachment to the email, but can find no way of viewing it.

Other than the use of DRM, the other differences are that M4V filesВ use the H.264 video codec exclusively, allowВ the storage of chapter information, and can deal with AC3 (Dolby Digital) audio files.

This prevents anyone attempting to view or copy these files on a device that isnвЂ™t made by Apple, such as iPhone, iPad, iPod, etc. The drag and drop option was not working on my laptop.

Assuming the mp4 video isn't corrupted, can be played with a video player, you would then simply open OpenShot, goto File, Import file. The main reason behind creating it was to put a level of security, which adds AppleвЂ™s FairPlay DRM protection, on anything from the iTunes Store. To open any file from the command line with the default application, just type open followed by the filename/path.

Developed by Apple, M4V files are very similar to the MP4 format, which areВ both based on the MPEG-4 video container format.
