- Description
- M4V is a video container that stores audio and video data used for iTunes files. Files of this type may be protected from illegal viewing and copying with Apple FairPlay DRM. In this case audio or video files should be bought in iTunes store. Not protected files can be viewed almost in any modern player because the format is based on MPEG-4 structure.
- An RMVB file is a Real Media video file compressed using a variable bit rate, which is optimized for the content of the video. It is a newer variation of the standard Real Media (.RM) file format that allows for more efficient compression.
