Hello. First of all, I'm sorry for using Google Translator. hope you understand. What I am curious about is the color of the result of shooting with hlg3, bt2020 on Sony a7m3. pic 1 is the color when the clip is posted on the premiere timeline. pic 2 is when playing the clip in QuickTime player. How can I get the color of pic 2 in the premiere and edit it to produce the result? Please help a lot.

I guess the first question I should ask is: is your intent to export an HDR file? Or did you just shoot in HLG/Rec2020 for editing flexibility, and intend on creating a Rec 709 SDR file at the end of the day?

 

If you're doing the latter, the one thing you really just need to keep in mind is that Premiere Pro works in Rec 709. If Display Color Management is turned OFF in Premiere, then you will see the video "through the lens" of your display profile set in your OS. If it's on, you'll see a close to Rec 709 reproduction. So in this case you may just wish to ensure you have color management turned on so what you see in Premiere accurately reflects Rec 709 standards

 

If you're trying to do the former...

TO EDIT HDR:  As mentioned PrPro uses a Rec 709 workflow. While you can set Lumetri Color scopes to Rec 2020 and work with the media, it unfortunately takes extra effort (and equipment!) if you want to get accurate HDR output on your display. R Neil Haugen has a great guide on this here: https://community.adobe.com/t5/premiere-pro/faq-setting-up-for-hdr-work-in-premiere-2020/td-p/106464...

 

TO EXPORT HDR: You will need to export in a codec that supports a Rec 2020 gamut, and be sure to enable that in your export settings. For example if you are exporting H.264, you would need set the Profile to High10 and check the "Rec 2020 Color Primaries" box. If you don't do any of this, the file will be exported as Rec 709, because that is the standard working space for Premiere.

 

I've also heard QuickTime Player has had some particularly nasty issues with color/gamma shift unrelated to standard color space differences, but I am not sure if this is specific to certain codecs. I admittedly have not experienced this myself. You may just wish to avoid QuickTime Player as a means to check your work. Bring the export back into Premiere Pro instead.

As awh11 noted, you can only properly "see" HDR media "within" Premiere if you have the external card and gear mentioned in my post that awh11 mentions. Premiere can only display Rec.709 images internally.

 

So with as awh11 noted, Display Color Management off, you may get a flat looking file, and with it on, you may get a contrasty blown-out view. Neither is of course correct, as ... again ... you need to have the proper gear to "see" proper HDR on your monitor ... which needs to BE a full HDR monitor.

 

And currently, Premiere can use the Rec2020 primaries inside a Rec.2100/HLG workflow. They're working on it of course.

 

So ... what is your monitoring setup? Are you trying to create HDR material for delivery, and if so ... where?

I'm just trying to follow along here, in awh's first post he said:

'So in this case you may just wish to ensure you have color management turned on so what you see in Premiere accurately reflects Rec 709 standards.'

 

Is the "on" in the middle of the sentance correct or a typo?

Correct, that is enabled or "on" for most systems. Especially on most systems not running a broadcast type monitor via external LUT box, or capable of internal LUT storage.
