Handbrake is an open-source, multi-platform video transcoder that supports a wide range of formats and facilitates video conversion. This free program allows converting the DRM-Free iTunes movies to MP4 format when it comes to iTunes movies. But DRM-protected film cannot be converted using Handbrake.
If you are looking for a free solution to convert iTunes video to MP4 on Mac, VLC Media Player proves to be a decent choice. Using this media player, you can turn your M4V videos to MP4 in good quality. Here it again needs to be remembered that only DRM-free files can be converted and not the DRM-protected ones.
Many movies, TV shows, and other video content purchased on iTunes have DRM Fair-Play Copy Protection by Apple to prevent illegal distribution of the files. DRM protected movies and videos cannot play on non-Apple devices and can neither be converted to any other format. DRM policy cannot be removed from the iTunes movies. There are different ways like recording or converting to play these movies on non-Apple devices, as discussed in the above parts of the article by Wondershare UniConverter.
