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. Videos in M4V format can be protected from being used for commercial purposes. But M4V cannot be opened in some device, so sometimes you have to convert M4V to MP4.
Filmage Converter offers you an easy way to convert M4V to MP4:
1. Open Filmage Converter;
2. Cilck Add Files -> Choose the file for conversion from local folder or by drading; 3. Click Format -> Click Video -> Choose MP4 and select different kbps with different quality;
4. Choose Where to save the converted file -> Click Convert.
5. You can also convert M4V to other formats as you want by following the same steps.
Note:
Due to the Apple's restrictions, M4V and VOB cannot be input on the version of App Store. If you want to convert M4V or VOB to other formats, please install Filmage Converter.dmg.
