I want to convert small clips of a 4K movie to .mp4 without losing quality so I can upload them to YouTube. Loading a whole movie into Premiere Pro and then cutting it at exact points is already a hassle because it doesn't support .mkv. Even if you mod it to do, computer resources are limited for me to drag and cut this file around in the program.
FFMPEG seems to be the best option, but even if I did manage to convert (I did earlier on another machine back home), the results would come out sloppy, choppy, and grey because of the HDR to SDR conversing problems. Has anybody gotten this to work?

I found another way to quickly remux MKV to MP4 using OBS Studio. This is a free and open source app intended mostly for video recording and streaming. The feature we need can be found in menu File > Remux Recordings.
