Rec 2100 HLG Display Issue

[CGBESSELLIEU]

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?

Not nearly enough information to help, and I want to help!

Skin tones don't match ... what? each other within the export compared to the sequences, or viewing outside doesn't match inside?

And contrast off from ... what, to what?

This has already been resolved per our earlier discussions in this thread! Can mark as solved. 🙂

I'm sorry, I'm bad with English and had difficulties writing. When I export my content and compare it with the Premiere Pro preview, there are differences in contrast, tones, and overall appearance, in the same screen of my macbook. I tested the sequence settings, clip settings, project settings, and export examples, but I couldn't solve my problem. Being limited in English, this whole topic is difficult for me to understand because translations are not accurate or don't make sense, but I appreciate your response and will keep looking!

Apple uses a non-standard display transform for both brightness and saturation for Rec.709 video files on most of their computers.

The official standard is gamma 2.4 for nearly darkened rooms, as is ALWAYS used as the working environment for professional grading, or 2.2 for bright office environments

Apple uses gamma 1.96 except on the Macs with Reference modes for the monitor, when set to HDTV. Those use the standard 2.4.

You have an option in Premiere's color management panel (the Settings tab of the Lumetri panel) to set your screen gamma in Premiere's Program monitor.

Set the Viewing gamma of the Lumetri Settings tab to gamma 1.96/QuickTime, and you will see the same image inside Premiere and outside on your Mac.

That is, when using QuickTime Player, and Chrome and Safari browsers. In Firefox or VLC player, you will see a much darker image as they will use gamma 2.4.

As will all PCs, Android, broadcast compliant setups, and most TVs.

Yea, it's a mess. Some use the Viewing Gamma setting of 2.2 trying to get somewhere in-between.

Check out the post I marked as "correct answer" above.

Do you have a display that can properly view HDR? If so, then make sure to check "Display Color Management" and "Extended Dynamic Range Monitoring". Also make sure both source and sequence match and are in Rec. 2100 HLG color space.

Viewing or converting to SDR will inherently change how it looks (given SDR by its very nature has less range of color and luminesence etc than HDR).
