Office Hours LIVE! 24 July 2024: Wrestling the HDR beast into submission with Dolby Vision

If you find yourself on every shot being like, ‘This one needs to be more aggressive. This one needs to be less aggressive,’ and things are really not matching, you might want to take another critical look at your HDR grade.

On this edition of Office Hours Live, host and Mixing Light CEO Patrick Inhofer is joined by colorist Joey D’Anna, and finishing artist Zeb Chadfield. The trio tackles five complex technical questions related to working in and delivering HDR and Dolby Vision projects.

Question 1

“Could you provide details on how the input, output DRT and timeline luminance work in Resolve’s project settings when color science is set to DaVinci YRGB Color Managed? Also how do these apply when working node based with color space transforms?“

Maria, Mixing Light Member

Question 2

“Can you provide some best practices for performing Dolby Vision trim passes?
What are the differences when working with gamma vs mid tone offset?“

Maria, Mixing Light Member

Question 3

“What is the best method to ensure proper and compatible delivery of HDR live event/wedding exports on a USB stick or hard drive to play directly on an HDR TV?“

Stefano, Mixing Light Member

Question 4

“Where is it best to place halation, grain, glow or vignettes – before or after the CST transformation to Rec 2020?“

Stefano, Mixing Light Member

Question 5

What are your tips for grading in HDR but for SDR-only approval and delivery?
