Is HDR10 with Rec 2020 P3D65 limited (1000 nits) possible?

Musicvid wrote on 6/11/2021, 10:39 AM

Every time I choose the output as P3D65 on the final render option screen it disables HDR10

That is correct.

As was explained before, HDR10 Mode is a simple preset and nothing more. It does not encompass any settings you choose outside those parameters. So if you choose another transform, such as P3, the HDR10 preset is no longer active. No mystery whatsoever; use the preset, or use something else.

Will you please look carefully at the Help section article I copied and illustrated for you previously? Thanks.

I understand that (and it might look like I don't) but I'm trying to do what the pros do with 4K Blu rays and have their color spaces be P3 within rec 2020. Almost all of them are like that and I understand why, because there's almost no TVs out there that can show all of the rec 2020 color space.

Choose the appropriate P3 transform if you have a P3 monitor. It is not part of the HDR10 preset, which is clearly stated as REC 2020. One or the other; they are not comingled.

@Teagan

Somewhat good tempered this morning 😄😄 and here the prompt answer:

Rec.2020/709 are standard and reference color space (definition)

P3-DCI/P3D60/65 are hardware color space (specification)

The fundamental logic is, you can take a definition as primary space but not a specification. 😌 Inversely, you can take a primary e.g. Rec.2020 and only use that much color gamut in it e.g. the P3D65 for HDR10-Rendering.

All these already prepared in Vegaspro, no brain-hitting.

The Wikipedia intro in addition:

DCI-P3, or DCI/P3, is a common RGB color space for digital movie projection from the American film industry.[
...

In September 2014, Eizo introduced during a fair trade Photokina in Germany the first consumer display CG-318 with real 4K resolution, supporting the P3 color space.

In September 2015, Apple's iMac desktop became the first consumer computer with a built-in wide-gamut display, supporting the P3 color space.

On January 4, 2016, the UHD Alliance announced their specifications for Ultra HD Premium which requires devices to display at least 90% of the DCI P3 color space (in area, not volume).[7][8]

In March 2016, Apple's 9.7-inch iPad Pro shipped with a display supporting P3 color.
...

In January 2019, Asus launched the PQ22UC, a portable 21.6-inch 4K OLED screen with 99% DCI-P3 colour gamut that can run over USB-C.[23]

In June 2019, Apple introduced the Pro Display XDR, a 32-inch 6K (6016 x 3384) screen with DCI-P3 10-bit color, 1,000,000:1 contrast ratio, and a wide viewing angle.[24]

In November 2019 Acer released their new studio laptop series called "ConceptD"; one of its laptop ConceptD 3 and ConceptD 3 Pro has 15.6-inch DCI-P3 Full HD display.[25]

Great! That is good to hear and know.

But I don't see the ones starting with P3-D65 nor the Apple ProRes options... Is that only in Vegas Pro 18?

I have Vegas Pro 17.

I'm afraid, yes. In the last update or so.

Well I'll probably be getting a camera that can do ProRes Raw in the coming months and will get Vegas Pro 18 anyways, so that sounds good and fair. The prores raw update, that I hear is coming, is exciting.

I'd probably wait for 19 and see what's supported.

Probably. We'll see around that time.
