Premiere color changes when exporting

Just in case this might help someone else - I figured out HDR is really the problem and just turned it off for future filming. If you don't care about the fancy quality it saves a huge headache!

My guess is that you're working with HDR video, possibly from a newer iPhone? What's happening is that your footage exists in a high dynamic range color space and you likely edited and exported in a standard dynamic range color space. What version of Premiere are you using? The latest public beta of 22.6 includes an automatic option to help fix this issue.

A couple things that can more accurately help you get what you want:

1) In Premiere, does the footage in your Program monitor look the same as the export in your screenshot?

2) Are you mixing this footage with SDR footage or are you only editing HDR footage?

3) If nobody will be watching the final file on a HDR monitor then you can tone map your footage for SDR by right-clicking on your clip, choosing "Modify > Interpret Footage," then looking at the bottom of the dialog. My guess is that the option "Use Media Color Space from File" is selected and the color space is Rec. 2100 HLG.

4) If so, can select "Color Space Override" and choose Rec. 709 to have Premiere tone map this footage for a narrower color space. Now, if you create a new sequence from your clip, it should look fine. If you already have a sequence you're working in, go to "Sequence > Sequence Settings" and check that the "Working Color Space:" is Rec. 709.
