Why Do My Premiere Pro Exports Look Washed Out? [QT Gamma Compensation LUT]

  • February 2, 2022

Hi There, 

Months ago I found a download here I think for the QT Gamma Compensation LUT ... I just updated my mac and now the file is a .cube and I don't know how to change it to a usable file again. Help? Does anyone know where I can find the file again to download & use?

 

[Moderator edited subject line. This issue relates to how a video exported from Premiere Pro might look different from how it appeared inside Premiere Pro. After export, the video may appear "too light" or "washed out". ]

    Hi all, 

     

    Premiere Pro exports appearing washed out is a commonly reported issue. It is caused by differences in gamma between devices like televisions, Windows and macOS computers, and viewers in different applications. 

     

    We have written an article that explains the cause of this issue and provides guidance on how to handle it:

      With such a minimalist post, I can't even guess at your problem. Or a fix. Details matter ... complete details. 

       

      And as this is a long-running older post that started in a completely different and now outdated color management system, START A NEW THREAD. Please.

      OK I've tried this for a few hours now and read all the replies. But my issue seems to be different... 

       

      The exposure seems much higher... the colors seem more bright and vibrant not washed out. 

       

      When I use the gamma compensation it makes it "more normal" but still unusably bright. Does anyone have any ideas?

      I don't know if this is very good but this seemed to solve the issue... https://youtu.be/cN8CHBhvyJs?si=Rz-oONMa1PuRMPG7

      Ok so this didn't work either... it now makes lines across the video like old school box TV's used to do.

      Hi, 

      Hi, is there any new solution to this on a mac? After exporting with "The Gamma QT Lut", the movie becomes darker and more saturated as mentioned earlier." Very grateful for tips.

      I reply myself here 🙂After reading Neal's earlier post, I will be running without "The Gamma Lut". When checking the reference in VLC, the films look good. Thanks Neil.

        How do you get away from using the Qt Gamma Comp LUT?

        I downloaded the LUT (which appears to be a load of text, but it works) from the link below then set export to h.264 (high-resolution 1920x1080) went to effects in the export window, selected the LUT from where I had saved it, and it worked perfectly.  Thank you for the advice!!!

          Hi - how did you get Media Encoder to recognize the LUT? I placed the cube files in a location and selected them, but it says there is a low level exception (see screen shot). I tried saving the cube file on my desktop as well as our video server, but it won't apply. I used the vimeo preset first and then tried the match source high bitrate preset, but it still shows as none. Thanks for the help.

          Thanks Neil - so I just did what you said and it said "applied" the encode looks good on the mac. I didn't realize that it would be very dark if viewed on a non-mac. So for review and approval the mac users will like what they see, but the PC users will see a darker encode?


          Yes.

           

          Because the problem is specifically caused by Apple's choice to use the camera tranform function ... essentially gamma 1.96 ... as the only tranform, skipping the also required gamma 2.4 display function added in Bt.1886.

           

          The "original"  Rec.709 was created while 'we' were still all using CRT monitors. Which had a specific native curve to the shadows of the signal.

           

          As digital "flat panel" monitors came into existence, Bt.1886 was addended to Rec.709 to compensate for the flat response of the digital panels. So that 'we' still got essentially the same image.

           

          That was back in the area around ... 2008 or so? Something like that. And all broadcast specs require the 'full' Rec.709 ... sRGB primaries, D65 white point, gamma 2.4 display transform, around 100IRE/nits total brightness.

           

          So my Rec.709 compliant system will display that file as you see it within Premiere, pretty close. As will any fully Rec.709 system.

           

          It's only lighter when viewed on a Mac, with apps that allow the Mac ColorSync utility to handle color management. Such as QuickTime Player, and Chrome & Safari browsers.

           

          VLC player and Firefox normally do not allow ColorSync control, so they can be easier to use to check non-Mac 'views' of a file.

            i am not aware that the lut doesn't work with mac. premiere reads the file so it should still work.

            download lut here:

            just place it in location here:

            https://community.adobe.com/t5/premiere-pro-discussions/faq-premiere-pro-lumetri-color-custom-lut-directory-and-location/td-p/4785911

             

            and render out with lut.

              Is this still a thing that needs to be done in July 2022 with latest Adobe?

                That of course, depends.

                 

                As the need ... or use of that LUT ... is caused by the Mac OS color management utility ColorSync applying a non-standard gamma to Rec.709 video files.ColorSync, for some reason, uses a 1.96 gamma.

                 

                So Rec.709/SDR video files are displayed with lighter shadows and mids on a Mac, than they would be if displayed with the "normal" Rec.709 gamma of 2.4.

                 

                Premiere always attempts to operate by the Rec.709 standards, including it's internal monitors which are not 'controlled' by ColorSync. So the image typically is darker within Premiere than outside on the same Mac computer.

                 

                That LUT will essentially push the midtones and shadows a bit darker in the exported file, so that when viewed on a Mac, outside of Premiere, the file will look more like it did while viewed in Premiere.

                 

                But of course, then outside of the Mac-sphere, on a non-Mac system, that file will now be a lot darker than it appeared on the Mac within Premiere. Because on non-Mac gear, the Rec.709 video file will probably be displayed with a correct 2.4 gamma.

                 

                So ... the choice is between two imperfect things:

                 

                • A bit light on a Mac, but "normal" outside of Mac displays without the LUT.
                • "Normal" viewed outside Premiere on a Mac, but too dark outside of the Macs.

                 

                That dilemma can't be "solved" by a version change with an outside app like Premiere or Resolve. The need/use of the LUT could only be changed by a change of the standard used by ColorSync.

                  Nevermind having a moment - it's fine.
