I’m a new user to FFmpeg and having some issues I can’t find answers to.  Here’s what I’ve done I’m trying to accomplish:
1.  I have some 4K DVDs that I made mkv file.  I want to put those in mp4/m4v for playing back on Apple TV.2.  I trying to use FFmpeg to remux to mp4/mv4 so I don’t lose quality of video.  In short, just trying to remux mkv to mp4/m4v
I’m getting the following error when I run this script:  ffmpeg -i /Users/goyo/Movies/Pirates_t00.mkv -codec copy Pirates.mp4I get the following error:[mp4 @ 0x7fa36306aa00] Could not find tag for codec truehd in stream #1, codec not currently supported in containerCould not write header for output file #0 (incorrect codec parameters ?): Invalid argumentStream mapping:  Stream #0:0 -> #0:0 (copy)  Stream #0:1 -> #0:1 (copy)    Last message repeated 1 timesI am not a programmer, just an end user looking for a solution to move my discs to playable storage. Looking for some direction and help.Thanks in advance.
