Dear all,
I'm going nuts. Filmed a project in HLG. Edited it in an HLG sequence but when I export it the colours are changing. I'm using 'Match Source HLG' but have tried a couple of other things with no luck. I've attatched screen grabs of the settings (the preview looks fine) and a screen shot of the exported file.
Thanks in advance!
Simon.

Hey Simon,
Sorry for the issue. Which media player are you using to preview the exported media? If you import the media back to Premiere Pro, do you still see the change in colors? Please also let us know if you're on a Windows or a macOS system.
Thanks,
Ishan

I work for/with/teach pro colorists, including the early adopters of DolbyVision, who were hired by Dolby to do the inhouse tutorials for colorists working with DolbyVision in Resolve for streaming/broadcast. I've been using Premiere since CS6, and was a heavy user of SpeedGrade before they killed it, Resolve since.
First note ... changing the graphics white setting to 300 is just weird. I don't know a single colorist who would use that, the 203 setting is by far the more common one. Understand, that isn't total brightness, just what a flat piece of white paper would be set to in a daylight shot. It's a crucial part of the data in the file, and changes how the screen maps the image brightness. Setting that to 300 means many screens will push much of the image down a bit. To fit their screen capability.
Next ... without seeing all of your Premiere color management settings, the only thing I could make is WAGs ... wild arsed guesses.
Please do a screen grab of your color managment settings ... Lumetri panel, Settings tab ... top to bottom. Not the color correction settings in the 'Edit' tab, the CM settings please.

Hi Neil,
Colouring is not my thing and I'm new to HLG I'm afraid so hence why I'm on here. Didnt even know what the Graphics White Setting was, I was trying anything eventually! I've attached a screen shot of the Lumetri settings.. I never noticed a box 'Display Colour Management' before, and when I check this it changes the colours to the undesired colours I was getting on the export. Again I don't understand this so any suggestions so that I can just export what I'm seeing on the preview monitor would be much appreciated - thanks.

So just to add Neil, should I have the Display Colour Management box checked and be colourising with this as the reference?
Thank you.

We also need your system details ... OS/CPU/RAM/GPU, I should have asked for that right off. There's a couple things that vary depending on whether you are Mac or PC.
For basically everyone not running a full broadcast-legal (calibrated and profiled) viewing setup, DCM should be on. Along with auto detect log and auto tonemap, again, unless you have a clear, professional need to manually manage those. Those two auto-settings are interactive, and having one but not the other gives outputs you have to know what you're doing to set properly.
AND of course, SDR/Rec.709 presets do not have HLG or PQ in the preset name, and if like your project, you're trying to run HLG, then you must start with a preset with HLG in the preset name. There's settings there you might not realize need to be set a certain way for success.
HDR is still the Wild Wild West, btw ... as noted, I work for/with/teach pro colorists, the majority of which have not delivered a single paid HDR gig yet. And included in that worldwide group are some of the earliest professionals using DolbyVision for streaming/broadcast.
Very few screens of the total "screen base" can actually do HDR, and those that can can only handle typically one or two of the what ... five now? ... conflicting HDR formats. But even of the screens that can do HDR, most don't do it well.
Including all but the few very expensive pro reference monitors will fade brightness up or down to protect the screen pixels from burn-in. Which you can't really see, but especially if you pause a scene to change something, will kick in. So your changes may not do what you thought they would in normal playback. And another screen will shift differently. It's maddening that way.
When right, of course ... it's awesome. Just ... ticklish to do, even for pros.
