Convert m4v to xvid

What is the difference between .m4v and .xvid?

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.; Xvid-encoded video files are digital video files that have been compressed and encoded using the Xvid codec, an open-source video codec designed for compressing video data in order to facilitate faster transmission over computer networks or for more efficient storage on computer disks. Xvid, which is a reverse spelling of "DivX," emerged as a popular format due to its ability to compress video files without significant loss of quality.
