Convert m4v to mpa

What is the difference between .m4v and .mpa?

Description: The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.; The MPA file format, standing for MPEG-2 Audio File, is designed to store audio data compressed using the MPEG-2 Audio coding standard. This format is a successor to the MPEG-1 standard, offering enhancements like improved audio quality and support for multiple audio channels, thus enabling surround sound experiences. MPA files are commonly used for both music and video soundtracks due to their efficient compression, which preserves sound quality while reducing file size significantly.
