I have a blu ray rip of the Dark night. Its in MKV format right now. The movie switches between imax (full screen HD) then letter box format. I want to convert for Atv3 and I have done a few test rips. The problem is that it formats the movie in letterbox and gets rid of all those amazing imax quality shots. Is there a way to convert it to mp4 and keep movie in its original state?
