Exporting and Color management

Actually, to add to my previous comment, I just tried exporting my video again without Lumetri and some clips were still over exposed. Turned out it was minor scaling. I'd made two clips 102%, and one clip 104% in size just to match objects in a jump cut. Those clips were way over exposed on export.

Finding the same issue, Premiere Pro version 25. Files are iPhone HDR, exporting with 2100HLG colour space. They look fine within Premiere Pro, but any exported clips that have Lumetri effects added, even for the most minor corrections, appear wildly over exposed

Updating the status of this bug report.

I see you've reported this as a 'bug', so of course you don't need to supply any of your settings, as it's a bug. But just in case, can you give an idea about what you are using and what you are doing. How about the OS, can we know if it's Mac or PC? Some info on the hardware, and some screenshots of your settings, just in case one needs to be tweaked. What did you shoot these clips with and what is your monitor. Cheers! 🙂

We would need to know what you're setting things for.

It sounds like you want to be working front to back in HLG? Ok ... understand, even for pro colorists, HDR is still the wild wild west. Not that high a percentage of screens yet actually do HDR. And among those that do, they typically only do one or two of the various HDR formats ... and few actually even do the ones they do do, correctly.

Some TVs are the bright spot in HDR playback, and some of the more middle/upper-expense monitors.

So ... depending on your OS and monitor and monitor settings, you may have a situation that works mostly ok. All computer monitors and TVs out now do shift exposure/contrast to protect the screen over time, so understand that 'holding' an image while grading it ... may end up looking rather different than during playback. Especially for short clips.

The only screens that don't do that are the expensive pro reference monitors. Flanders now has a 31.5" model that can do 1,000 nits and does not do the auto-dimming at all. For only $9,995, which is half the price of most other pro HDR reference monitors.

Ok ... first, make sure your OS and the monitor are both set for and working in HLG for what you want to do. Curious ... how bright is the monitor, supposedly? In my experience, never trust monitor data from the manufacturer (except Flanders) ... check with probe/software to know what you're getting.

And any pretty certificate showing how your BenQ or Asus or whatever monitor meets certain standards? Pretty much junk. I've never had a monitor where the factory Rec.709 or P3/D65 or whatever setting was actually ... measured ... even close to what the certificate said. Your mileage will vary.

In Premiere, set the Preferences options for Extended Dynamic Range when available to on. 

Auto detect log, auto tonemapping both on. 

Set the Working Space to HLG/Rec.2100.

Use export presets with HLG in the preset name.

If that doesn't work, post back, we'll go through your settings and see if we can puzzle out what's going on.

And if on a Mac, and ColorSync is involved ... as in QuickTime player, Chrome, Safari ... that is another issue. Though maybe not as bad as in Rec.709 workflows.
