Rec 2100 HLG Display Issue

I'm having an issue with how the Rec 2100 HLG is being displayed in Premiere. Note: this is not the common issue of needing to set to correct color space in project settings. Everything is set correctly.

 

But it seems despite this, as the screenshot shows, if you play the footage in Windows Media Player for example and compare to the display in Premiere, it looks a bit desaturated and overexposed. This happens with exported files as well, even when they are set to correct color space.

 

Again to be clear this isn't the issue of it being set to the wrong color space in export because then it's extremely overexposed and blown out. Here it's a bit more subtle, but still quite noticable to be an issue to my client.

Also there is no extra LUT or color grading preset being applied here. It's the natural raw display. Any ideas?

Unfortunately you're hitting something you cannot completely fix. Nearly all colorists have a clause in their contract limiting all acceptable comments must be from viewing on specific monitors in controlled viewing circumstances.

 

As not even a pro colorist can absolutely match two "identical" monitors, fed the same signal, in the same room. With spectrophotometers costing more than you or I have in our total desktop computer setups.

 

That's just Reality. And as annoying as it is unavoidable.


OK super weird. So today woke up and noticed that now everything lists as 2100 HLG in the color settings and that "color spaces match". Initially it was super blown out and I was confused why everything had changed, then I clicked "extended dynamic range monitoring" and now it looks closer to the source footage, and that detail I was talking about in the beard etc seems to be there now in Premiere! 😄

Just a couple of guesses:


Try unchecking Composite in linear color in the sequence settings.
If that doesn't work, try turning off Hardware encoding in the export settings.

"Composite in linear color" is unchecked (and greyed out) in sequence settings.

And export settings are already set to software encoding.

Did you manage to solve this problem? Could you send a list of the changes you made to fix it? I have the same problem, everything is correct, converted, I even used the SDR during export, and the skin tones don't match, and the contrast is also off even after adjusting.

Would you mind telling your sequence settings and deliverable intent? Is it Rec.709 or Rec2100 HLG? From the screenshot it simply looks like no conversion is applied and no display management either. You are simply looking at the HLG encoding as is which looks greenish and desaturated. If you want to create SDR video the sequence should be set to Rec.709. To view and manage it properly Auto Tone Map should be enabled and the clip interpretation should be set to Rec2100 HLG.

Deliverable intent is to keep to the Rec2100 HLG color space. As you can see the sequence settings are set to that and Auto Tone Map is enabled.

What does it look like if you play the export in Premiere?

It looks the same, has the same issue playing the export in Premiere.
