M4V file format is a video file format developed by Apple and is very close to the MP4 format. The differences are the optional Apple's Fairplay DRM copy protection, and the treatment of AC3 (Dolby Digital) audio which is not standardized for the MP4 container. With DRM (Digital Rights Management) protection, users could just only play their iTunes M4V TV episodes, movies, and music videos in portable Apple devices.
With M4V to MP4 Converter, you can convert M4V to MP4 format that can be freely played on various non-Apple devices, such as Android tablets/phones, Windows RT tablets, HD media players and etc. AVS4Mac M4V to MP4 Converter is an excellent and easy to use M4V conversion program. It can convert iTunes M4V video files including your purchases or rentals to various formats with perfect output quality and high conversion speed.
AVS4Mac M4V Converter Plus is the best M4V to MP4 Converter that provides two kinds of MP4 output formats for users-Same as Source for MP4 & Customized MP4 Video. Though both of the two formats produce .MP4 output files, they still have some differences.
Generally, the best output format is H.264 video with AAC audio in MP4 format. Because H.264 currently offers the best video compression available. And the profile "Same as Source for MP4" has chosen H.264 video and AAC audio by default. So uses can produce output videos with high quality. But as the parameters are the default, meanwhile users can't adjust the settings. While the profile "Customized MP4 Video" offers user DIY experience to set the parameters such as Video Size, Video Codec, Video Bit rate, etc. But sometimes most users don't know the best settings. So the qualities of output videos may be not that perfect.
Consequently, if users need high-qualified output and know less about the best parameter settings, the profile "Same as Source for MP4" is preferred. On the contrary, if users need high-customized output and know much about parameter settings, the profile "Customized MP4 Video" is another good choice.
Both Mac and Windows version are available for AVS4Mac M4V Converter Plus. You can download it according to your OS.
