HDR Discussion Thread

[Penton-Man]

Offhand, I can’t recall which thread in this forum people were discussing scanning, telecine – DI, etc. but here is recent colorist meetup with Lynette Duensing, one of the few people who were lucky enough to be given an opportunity to work on the very first telecine machines and film scanners. Domestic trailer Bad Boys, Sicario (blood removal/reduction, etc.) and Greyhound (https://www.imdb.com/title/tt6048922/?ref_=ttfc_fc_tt ) discussion beings around 40 min. timestamp -

on a side note, specifically Shane ^ is well trued - https://forum.blu-ray.com/showthread...e#post16553315

and with regards to colleagues they all look up to, might I add that I have heard no complaints from the intended audience (those not viewing in a reference environment all the time) with regards to Dolby Vision IQ thanks to the efforts and foresight of the following inventors - https://patentimages.storage.googlea...70116963A1.pdf

shot with the same type camera as above ^, but different type movie – https://britishcinematographer.co.uk...ardy-bsc-devs/

and graded in HDR, of course. Also, as a historical tie-in to puddy77’s post above, in this month’s 100th edition of British Cinematographer there’s a good article on the evolution of color grading

”An example of this would be shooting with HDR (high dynamic range) delivery in mind. By using the AJA Hi5-12G-R-ST converter, you are able to receive a long ST or LC fiber optic cable run that connects directly to the converter. The converter then is able to generate HDR10 or HLG metadata via its HDMI v2.0 output without any extra conversion, so the image can be viewed appropriately on HDMI HDR monitors on set.”

Has there been any news of ICtCp being used in anything other than Netflix?

[tyler2tall147]

Have Sony or Microsoft confirmed if the X1SX or PS5 will support Dolby Vision from 4k Discs?

Vudu and Apple TV4K use Profile 5 for DV streams, which use the ICtCp color model, whether or not its in the grading workflow, I don't know.

It was exciting when Dolby announced the ICtCp, and it seemed like a big deal. But that was it. No mention of it again. Very strange.

Profile 5 which utilizes ICtCp color already is the most widely used profile amongst Dolby’s OTT streaming partners. Now, among other things, Dolby is busy researching and likely fairly close to implementing functionality that would allow one to take the home master (say done at 1000 nits) and be able to map not only to consumer TVs but also to cinema projectors, be it the 100+ nit Dolby laser projector or a 48 nit DCI cinema projector.

So they are using dual screen LCDs. What about dual stack OLEDs? One company claims 7000 nits for their DS OLED micro displays.
