I'm completely confused on Total Recall releases and restrained getting the UHD due to the LD sync being at a different framerate and asking us to doctor the UHD from 24fps to 23.976fps.
I experimented with this about a year ago, and found I had problems changing the UHD video framerate with both eac3to and tsmuxer. The issue was that the Dolby Vision layer didn't seem to survive the process intact. tsmuxer has had many updates since then, so perhaps it might work better now, but I haven't revisited it. Chewtobacca (banned?) also indicated that ffmpeg might be able to successfully do this, but again I have not tried it myself.
I'm using the latest nightly tsmuxer from the github and retiming the DV layer works. You just have to be sure to change the speed on both video track 1 and 2.
