TuneMobie M4V Converter Plus for Mac converts iTunes M4V media to MP4 without any loss in quality. This software retains multilingual subtitles and audio tracks, and Dolby 5.1 for enjoyment on any device including iPhone, iPad, Android, PSP, and Kindle Fire.

One of the standout features of TuneMobie M4V Converter Plus for Mac is its lightning-fast conversion speed. It's up to 30 times faster than other similar software, so you can easily convert an entire batch of videos in a very short amount of time. Plus, you can be confident that the output MP4 files will have the same resolution and 100% original video quality as the source files.
Using this converter is a breeze. It automatically loads your iTunes video library upon launch and displays your purchases and rentals as a playlist in the left panel (just like iTunes). This makes it easy to choose which files you want to convert. And, of course, the software fully supports macOS Sierra and the latest version of iTunes.
Once you've converted your M4V files to MP4, you can enjoy them on a wide range of devices, including iPhone, iPad, Samsung Galaxy S8, Huawei Mate 10, PSP, PS3, PS4, Kindle Fire, and any other MP4-compatible devices. The possibilities are endless!
Overall, I highly recommend TuneMobie M4V Converter Plus for Mac. It's reliable, user-friendly, and gets the job done quickly and efficiently. It's a must-have for anyone who wants to enjoy their iTunes M4V videos without any restrictions.
