I think I tried exactly that based upon this stackoverflow question:
https://stackoverflow.com/questions/64981984/ffmpeg-transcode-uhd-h265-to-sdr-h264-without-color-loss
The example in that post uses this command:
|ffmpeg -i 4K.ts -vf
zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p
-c:v h264 -crf 19 -preset ultrafast output.mp4 |
Which I thought might be my solution but when I tried it, it ended up
making the video too red.
Does that look like the route I need to take?
