Premiere HDR without dedicated card on Window 11?

With the changes to Window 11 HDR I was wondering if it would be possible to change to a HDR workflow without getting extra hardware.


I have a Sony A90J TV that has almost professional grade HDR which is connected to a RTX 3080TI.  If you have an HDR TV currently premiere still requires you to have a dedicated card like the UltraStudio 4kMini which costs 1k dollars and adds unnecessary clutter every time I want to edit in HDR.

 

With Windows 11 reworking HDR to make games better support it natively I was wondering if there wouldn't be a way for premiere to make HDR work RTX 3000 series cards.

Currently, I can set to HDR by simply switching the Windows setting for my "reference" monitor to HDR. That triggers the monitor's HDR mode. And is recognized by PrPro, though you have to go to the Sequence and Scopes panels and set working properties to HDR.

 

And that isn't through any BM or AJA hardware.

 

Now ... my monitor only goes to around 350 nits, so bluntly, that ain't no real HDR. I'd never work that way. But I can 'force' HDR that way.

 

But as, if not more important ... most monitors and TVs have auto-controls that adjust contrast and scene levels, especially black & white points, during playback of HDR media. I don't know of any screen other than those flipping expensive full-on HDR reference monitors that doesn't.

 

And that is an issue if you're trying to adjust the luma/chroma of the sequence, as you don't know when the monitor is fudging things on you.

 

On the LG C1 and CX screens, you can go online and get a technician's remote for them, and from that turn off most of those features ... mostly sort of. Naturally, after doing so, you have to be careful you never just leave the thing on with a static HDR image up or you can damage the screen.

 

And you really need to run them from a BlackMagic or AJA LUT box, with a LUT you've made from Calman or Lightspace to be sure you're looking at "real" values.

 

It's one of the real pains of trying to work out with some HDR at this time. Anything that works correctly for video post work is the cost of a new car. The things that are more reasonable all come with massive caveats. I find this all very frustrating.

 

And yea, I've got friends with $20,000 to $32,000 in HDR monitors. But no way I could ever justify the expense.

 

There's the new Asus and Dell monitors for around $4-5K. But even with those, you still should have the LUT boxes feeding the monitors. Flipping expensive to do HDR yet.

woah, slow the horsey down before we all start jumping up and down.


Adobe’s Mercury Transmit for devices - aja and blackmagic is the only true HDR viewing enviroment where the HDR viewing data gets sent.


There is a mod called 'new project' to force SDR graphics white point to 203, or 300 nits.(I'm guessing this is a legacy offshoot of Apple's retorted EDR displays) which doesn't use 2100 or PQ gamma curve.

 

some people say working in 'super bright' SDR helps you view HDR footage. mmm. I don't know about that one.

Little clue what you're talking about there, sorry.

 

As they've posted in a couple threads here and the public beta, we can now work in HDR if the OS and the monitor can, and we set the timeline/sequence settings to either the HLG or PQ that Premiere works in.

 

The scopes need to also be set to the same color space option. And yea, it might need to be using the transmit out, but the BM or AJA output device isn't quite necessary anymore,

 

And the setting for diffuse white ... the 203 or whatever option your choose ... is the weird way of setting the diffuse white point that is used in HDR calculations. Though it all seems very patched together still.
