Clients Unhappy With Your Downstream SDR Tone Mapped Color Grade?

From The MailBag Episode 68

HDR TO SDR Tone Mapping – Keeping Clients Happy

One day, we might live in an HDR world where all displays can do the full range of brightness that is part of current standards. But the fact is, right now, there are HDR displays of varying brightness and color volume, and SDR -BT.709 displays are the universal standard.

This week we got a question from Mixing Light member Will who asks:

Hey Mixing Light, What’s up?  I’m a Chicago based finishing artist and the place I work has a Dolby license for trim controls in Resolve.  I’ve felt like I have had a good mastery of these controls, but recently several clients in a row weren’t happy the results of the SDR trim I made – and I kind of see their points.  Any suggestions? Help!

-Will

Will – your timing couldn’t really be any better. This subject of Dolby Vision tone mapping and specifically to the 100 NIT REC 709 target has been on our minds recently given some recent hiccups I had with a project. Dolby Vision was also the subject of much discussion at NAB 2019 in various pockets of colorist gatherings.

In this installment of From The Mailbag, we discuss the question of SDR tone mapping and ponder a few related issues.

  The biggest problem we faced is clipping in the highlights. In a pure SDR workflow, you’d have the tools to control those separately from the foreground to keep details in there. The DV SDR does not allow this of course. What I faced is DOP is taming down the HDR so the SDR looks better. To me they really loose a lot of the HDR effect. And I don’t mean OverHDR effect.

  yes. I agree. Soft clip in the trim controls would be a huge addition, or a modification to the highlight clipping control thats currently there – I also think highlight saturation control would be huge in the trims. I’ve asked Dolby a few times for these things. Worth an ask on your end too!
