  Yes.
  
  [M4V](http://en.wikipedia.org/wiki/M4V) is a slight extension to the [MP4](http://en.wikipedia.org/wiki/MPEG-4_Part_14) container format. M4V is Apple's version, which adds optional DRM-encryption.
  
  So if the video is DRM-protected (i.e. came from the iTunes store) it should stay as m4v (and will open by default in iTunes). If it's not, it can be used with either extension, and many players will be happy either way. By default, .m4v files will open with iTunes, which may be convenient.

  **Yes**, this simple conversion should work fine. Both files are technically mp4 files anyways.
  
  Notably, certain older Apple products, like older versions of appleTV for example, require it to be in m4v format so **don't forget to switch it back if you're switching between a Mac and a PC if you are using older mac products.**
  
  By default, m4v files will always open in iTunes vs other programs.
