I’m amazed by the SDR8/SDR10/HDR10 → DV mapping done by the VS10 engine. I honestly did not think it would be so great. It seems to compensate for inherant drawbacks of projectors (compared to OLED screens)
- Configure in player-led HDR mode thanks to the cpm VSVDB build (so it even works on non-DV projectors) → EDID Override - Injecting a Dolby VSVDB Block - #94 by cpm
- color is a little bit more saturated than in pure SDR but it still ok, so you need to do a fine HDR calibration to avoid too much saturation.
- If min and max lum are well configured through EDID / VSVDB injection (check the VSVDB thread for excel EDID generator), you can then look for the projector max contrast value that still keeps details in brights spots. In my case I have set a fixed number and I don’t have to touch it anymore (set and forget → it was not the case with pure HDR10 signal).
- HDR10 challenging material with crushed brightlights are now completely well managed and profit from the VSVDB induced fine tuning (especially on projectors I guess). Though I might be biased by my projector’s HDR10 tone-mapping which I think was pretty bad.
- With SDR->DV conversion, perceived contrast is improved on projectors : In other words, there are less cases in low light scenes where blacks seems grey. I don’t know how they did it but it’s near magic
I think it’s mostly due to highlights beeing brighter in SDR->DV conversion.
It might even be superior to embedded DTM in JVC projectors. I would be interested to know the result of such a comparison.
