Problem: spent hours doing a green screen edit, fixing lighting and colour/shadows etc, then when I export I get a completely different image. Looked it up and I am not the only one: this trick seems to fix it for most. for me, that solution brought down the intensity but then showed greenscreen backdrop.
OS: Sequoia 15.2
Computer: Mac Mini, Apple M4
Premiere Pro version 2025 (latest, was just downloaded days ago)
Video was shot on a Google Pixel 9
original footage specs:
dimensions: 1920 x 1080
codecs: HEVC, MPEG-4 AAC
Colour profile: BT.2020 HLG (9-18-9)
screenshot of original footage:
all effects to colour was using the Ultra Key effect controls:
this is what footage looks like after edit when ready for export , followed by what it looks like when exporting/exported. last shot at the end is wondering about the "auto color" setting that seems to have happened upon export
after search online it seems i am not the only one (see you tube video below)
problem is for me when i apply this fix then my greenscreen backdrop shows up in the video.
help please!
Thank you!

Ok, now we need to know what your entire color management was set to. Lumetri's "Settings" tab has everything on it.
Twirl down everything ... project on down ... it may take a couple screen grabs to get it all in.
You proably should have Display Color Management, Extended Dynamic Range (really this one only on Macs), auto detect log, and auto tonemapping on. Use a Rec.709 sequence color space, and export ONLY with presets that do NOT have HLG or PQ in the preset name.
You will note a bit of a difference inside Premiere and the exported file outside if you view in Qt player, Chrome, or Safari. But not if using VLC, Potplayer, or Firefox. Thanks to Apple being ... Apple.

Ok ... first question, do you really need to be in HDR?
It's a serious question as at this time, we're still in the Wild Wild West in HDR. The majority of screens still don't do it at all, those that do only do one or two flavors, and probably don't do those all that well.
And yea, when it works, it's awesome. I first saw any of my work in HDR at NAB 2019, while giving a presentation on Premiere's color management in the Flanders FSI/MixingLight booth ... Flanders makes some of the high-end Grade 1 Reference monitors, and they had their newest 30-some inch HDR rig, a then $30,000 plus monitor, that we speakers used for our presentations.
Oh ... freaking ... my ... !!!!!!
We expected HDR would be 'done' in another year or two. And finally Flanders has a new monitor to replace the original one ... that screen type died an early death when the maker went belly up ... and there hasn't been a good option since. Until last June or so.
But... depending on your answer, I can give the CM options you would need.

For the camera first, turn off recording in HDR ... that will make life easier in the future.
For this ... Display Color Management, auto detect log, auto tonemapping, and sequence CM space set to Rec.709. Understand then that due to the change of Apple's display transform to the odd number of essentially gamma 1.96 ... rather than the Bt.1886 standard of 2.4 ... you will see different images outside of Premiere depending on how you view it. On Macs without Reference modes, that is.
On Macs without Reference modes, Qt player and Chrome and Safari, you'll see an image with a display transform of gamma 1.96. In VLC and Potplayer, the same file will probably play with a display transform of gamma 2.4.
The rest of the world (mostly) sees the image similar to VLC and Potplayer, as they follow the standard.

Thank you so much for your help! Admittedly alot of what you wrote is a foreign language to me but I am chipping away at learning these settings!

Set the Premiere CM to what I suggest. As you go down the panel, you'll see where those options are spread out among the sections.
Color is simply a mangled thing, realistically. As someone who works for/with/teaches pro colorists. None of our devices actually "sees" color. They manufacture color via amazingly geeky workarounds, whether it's the camera or your monitor screen. That "it" works as well in general as it does is probably the more amazing thing.
