- 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.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
