Hello,

I have a Dolby Vision profile 5 MKV that I am trying to conver to MP4 for playback on my apple tv as it only supports P5 in an MP4 container. What would be the proper workflow if the MKV has one video stream, one audio stream, and multiple subtitles?

i thought a simple `MP4Box -add file.mkv -new new_file.mp4` would work but it looks like only the audio stream got muxed over. 

Thanks in advance for any help.
