How to Convert VOB to M4V Format?
What is M4V?
M4V is a file container format used by Apple's iTunes application. The M4V file format is a video file format developed by Apple and is very close to MP4 format. The differences are the optional Apple's DRM copyright protection, and the treatment of AC3 (Dolby Digital) audio which is not standardized for MP4 container.
Apple uses M4V files to encode TV episodes, movies, and music videos in the iTunes Store. The copyright of M4V files may be protected by using Apple's FairPlay DRM copyright protection. To play a protected M4V file, the computer needs to be authorized (using iTunes) with the account that was used to purchase the video. However, unprotected M4V files without AC3 audio may be recognized and played by other video players by changing the file extension from ‘.m4v’ to ‘.mp4’.
