However, these options doesn't work if you want to convert iTunes m4v movies, TV shows or music videos to mp4 since iTunes uses DRM to pretect its video files.
The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection.
Apple uses M4V to encode video files in its iTunes Store. A DRM-protected M4V file can only be played on 5 computers (using iTunes) or iOS devices (using TV app) authorized with the account that was used to purchase the video.
M4V files that are not protected with DRM restrictions can be opened in VLC, MPC-HC, Miro, QuickTime, MPlayer, Windows Media Player, and probably other media players. Google Drive supports the format as well.
