I tried also to convert adding -vf format=yuv420p, but both the 10bit
and 8bit output files are distorted when playback with vlc, mpv or ffplay.
In comparison testing with my highest ProRes hq 10bit video file as
input (not HDR), the output mp4 file looks fine with the same ffmpeg
code line.
Was there a download site with small HDR10 test clips available, so we
can test and compare using the same input?
