Playing SDR video without inverse tone mapping in Plasma HDR mode.

[laichiaheng]

Question:

1. If I don't apply --inverse-tone-mapping, but apply --target-trc=pq, --target-prim=bt.2020, --target-peak=366 and --target-colorspace-hint, does it only increase the brightness of SDR video?

2. Does it also expand the color space of SDR content to BT.2020 when I apply --target-colorspace-hint? Or it is limited in Rec.709?

3. Is the --inverse-tone-mapping only an experimental feature?
   The image looks so weird to me if I apply --inverse-tone-mapping, the white area becomes too bright, the color of skin is weird too. It seems to look better when I play SDR videos in HDR mode without --inverse-tone-mapping.

1. Maybe you need a profile to trigger these options only when the video is HDR
2. I'm not sure, perhaps it depends on your monitor?
3. --inverse-tone-mapping expands SDR to HDR, so it's actually different from the original SDR movie, and of course looks strange

Would you kindly insight me on the syntax for such a profile, @Ptilopsis01?

profile-desc=HDR_video
profile-cond=(p["video-params/gamma"] == "pq")
