Secondly, you need to add HDR meta data to your source.What’s the best way to do that?
I think a tool like Mkvtoolnix can do it, but I’m not sure, since I have not actually done it myself.
Last question, when you say to add HDR metadata to the source, are you talking about the test image that’s already in HDR or the reference image?
I’m a bit confused. You want to match an HDR source to an SDR reference?
The test image is a 4K HDR source and the reference image is taken from an SD Laserdisc.
Ah oke, and when does it look pale? After rendering with a LUT?
After I apply “Build color matching model”.
I’m a little confused, because for the example you posted, the regrade does not look pale.
For this shot, the colors came out that way (notice around the lamp by the door)
https://screenshotcomparison.com/comparison/27055For the example I posted, even if the regrade doesn’t look pale, the colors aren’t accurate. Notice around the woman’s face.
If you mean the intensity of the lamp you might try reducing the smoothing parameter to 0.001. With regards to the woman I don’t really see the inaccuracy. It looks fairly accurate to me. There are some yellowish color splotches around here nose, but these also appear in the 4K UHD source if you bring the contrast and saturation to normal levels.
