What is M4V?
Developed by Apple Inc., M4V is a video container format that is very similar to MP4, especially by keeping a good balance between video quality and its size. Apple uses this format to encode video files, such as music videos, TV shows in iTunes Store. QuickTime Player natively supports M4V files, of course.
Unfortunately it is not that easy to open M4V files in iTunes or QuickTime Player. Only M4V files meeting specific requirements can be played in iTunes. M4V file has to be either encoded as 540 kbit/s (minimum) MPEG-4 video (H.264) with an approximately 128 kbit/s AAC audio track or as a 1.5 Mbit/s (minimum) MPEG-4 video (H.264) with a minimum 128 kbit/s AAC audio.
So if you have an M4V that doesn't meet the above requirements you'll have to go through format conversion and codec search and installation. Or you can download a Mac M4V player - Elmedia - to play M4V on Mac as it is.
