Premiere Export no lumetri color

Report · Feb 03, 2022

Hallo liebe Community,

ich habe ein simples Video gecuttet und einfach mittels Lumetri Farbkorrektur leichte Abänderungen vorgenommen. Leider entspricht der Export nicht der Vorschau ansatzweise. Der Export ist deutlich blasser.

Weiß jemand woran das liegen kann?

Habe schon alles Mögliche ausprobiert...

Beste Grüße

Max

Actually it is Rec709 and its not that kind of failure, but thanks for your help. Immediately favored it 😄

How are you viewing the export, what does it look like if you watch the export in Premiere?

Report · Feb 03, 2022

I am working with the latest Macpro with MacOS Monterey 12.2 with 4K 50fps Footage within the latest PremierePro-Version.

On the left Side is my Output played by Ouicktimeplayer out of the Macbook. Rightside is my Preview before Exporting at Premiere Pro on my Macbook. Like you can see the Output is less saturated and like faded over the whole image.

I did different Exports and all look exactly the same.

Best regards

I couldn't guess without knowing lot more, and screen grabs drag/dropped onto the text reply box would be SO useful! Details of the OS and media involved would be needed also.

If you're on a Mac and working in SDR/Rec.709, there's one potential issue. If your clips are HLG/PQ, that's another potential issue. Just for starters.

Hi Maximilian,

Sorry about this. First of all, do not evaluate any exports with QuickTime Player, try another Player like VLC. QuickTime gamma may display on your Mac might have no bearing on what your actual export is looking like. You say that you have a Rec. 709 workflow, but I would really like to know which camera was used to create the video clips in the first place. A screenshot of your Export Settings dialog box and another of Clip Properties might reveal a detail that could change things. Basically, we need more information about your workflow. That would really help.

Thanks,
Kevin

Hi Kevin,

the "camera" has been an Iphone 13 within the App Filmic Pro because I am cutting Tiktoks through that.

Format in Export: H.264 Matching Souce with High Bit-Rate. Bitrating VBR 1

Goalbitrate: 50 (Highest possible)

Maximum Render Quality

For GPU: M1 Max

The thing is - even if I use VLC and airdrop it on my Iphone, the faded and less saturated settings like in Quicktime are the same when i play it on the iphone.

One thing which is quite difficult is the step that i can't decide which renderer i am using inside the settings.

I noticed in a few answers here in the community that this can be a problem solver, but i can't change it and don't know why.

If you need more information, please name what exactly.

Thanks to you at this point for your answer!

Best regards

A very easy problem to diagnose. ColorSync strikes again!

Sadly, Apple for some unknown reason chose to create their own 'standards' for Rec.709/SDR video media within their color management utility, ColorSync.

Specifically they do not follow two of the required provisions of the long-used Rec.709 standards. They apply only one of two required transforms, and they apply an odd gamma. So there's no required display transform funtion applied by ColorSync, and they use gamma 1.96 rather than the specified 2.4.

So, on a Mac you must make sure the preferences option for "Display Color management" is checked on. This tells Premeire not to assume a correct Rec.709 display, and it checks the ICC profile/OS to see what is being used, and modifies the image within Premiere to get the closest to a proper Rec.709 viewing of the image data possible.

This gives you the best chance to get a good Rec.709 file out of Premiere. That's all Premiere can do.

Outside of Premiere on a Mac, it's a problem. Chrome and Safari browsers and the QuickTime player all allow ColorSync to mess with the video color/tonality. Firefox browser and VLC player typically do not, so you will tend to get more realistic Rec.709 images viewing in Firefox browser and VLC player.

I'm sorry, but there isn't any "fix" for this, as when Apple chose to apply different standards they chose to make everything different.

Adobe has provided a "gamma compensation LUT" and Davinci Resolve has an export option of "Rec.709-A", and yes, A is specifically for Apple. Both options get the same result, by two different processes.

The Adobe LUT darkens and oversaturates the file on export, so that outside of proper Rec.709 viewing as on a Mac, it looks mostly like a 'normal' Rec.709 file. However, on a normal proper Rec.709 system ... and most PCs ... that file will be way too dark and oversaturted.

The Resolve approach adds a different NCLC tag to the file header, which actually gets ColorSync to show the file with correct Rec.709 settings. However, on most PCs and proper Rec.709 systems, the result is the same as the Adobe LUT: the file is seen way too dark and oversaturated.

Among other things, I'll bet you haven't noticed that all professionally produced SDR/Rec.709 video media you watch via QuickTime player or over Chrome and Safari browsers have exactly the same thing done to them as what it does to your files?

Why? Because of course, you're used to what that screen shows you as "correct", and you've not seen what the colorist actuallly produced on a guaranteed tightly calibrated & profiled Rec.709 system.

Hey Neil,

thank you for helping me out.

Hereby i am sending you my preference-settings, maybe here within something is wrong which can fix that.

Otherwise - where can I get that gamma compensation LUT? I mean this can be an idea, but also seems to have problems at last if i am using this for social media postings because different mobile devices are using the plattforms and colours are going to be way different...

DaVinci Resolve is actually no option atm for myself.

Is there another possibility?

Also see my answer to Kevin inside the settings for more possibilities?

Thanks a lot!

Best regards

That LUT is still listed somewhere, but I've seen a number of people saying it goes too far. You could easily roll your own, actually, in Lumetri.

Just go to the Curves tab of Lumetri, the RGB Curves tool, and click about an eigth or a quarter of the way up from the bottom, and drag down a very small amount. Then go to the Creative tab, and up Vibrance and Saturation about 10-20 points each.

Export a file with those settings, and view it in QuickTime. See what you think. Adjust to taste.

Then when you like the results on several different clips, go to the Lumetri tab title bit, click on the 3-bar menu to the right of the word Lumetri, and choose save as a .cube.

Then park that somewhere you can navigate to it easily. They have a chart, I've put mine in the Program Files/Adobe/Common/LUTs folder. Now it's available for further use either within Premiere or via exporting.

To use it on export, go to the Export dialog's Effects tab, select the LUT option, and select the LUT you've made. It will be applied to the file as part of the export encoding process.

Just understand ... it will darken and up-saturate on all viewing platforms, so most people that roll their own try to get a middle ground where it's not as light/low-satuarated on a Mac, but not too dark/oversaturated on PCs and everywhere else.
