    Does Premiere CC2018 fix "wrong LUT problem"?

    Alberto Bedin Level 1

      In Premiere CC 2017 if you apply a LUT from the creative folder, then add new LUTs to the creative folder and re-open your project, you get the wrong LUT.

       

      In addition in Premiere CC 2017 if a colleague sends a project to you and he has different LUTs installed, when you open the project you'll get the wrong LUT (a random one, because Premiere uses a simply numeric array: that's so stupid).

       

       

      I read something about this problem in the change log of CC 2018. So my question is: are LUTs now consistent in CC2018?

       

      Did they fix this HUGE problem? Please don't tell me to apply LUT using "browse" because to be able to see the preview of the LUT inside Premiere is very important

       

      The problem is here since CC 2016!!

       

      Thanks

          Hi Alberto,

           

          Did they fix this HUGE problem?

          In Premiere Pro CC v12.1 & v12.1.1 you can now install custom LUT files & have them appear in the Lumetri Color panel. Premiere Pro scans the folders at launch and loads LUT files from these directories.

          More information here.

           

          Thanks,

          Kulpreet Singh

            Thank you. So now if I'm editing on 2 computers with different LUT installed, if a LUT is used and installed in both computers, I'll find it opening the project on both computers?

             

            This was not working on previous versions. Please could you double check this? I would like to be sure before upgrading.

             

            Thanks

              The problems you were experiencing before were caused by tampering with the LUTs within the application package - please do not do this. It was never advised or supported by Adobe engineers. This was never a bug on our end.  I know that there are several very official looking tutorials and instructions out there that tell you to do this, but it's still wrong and causes many problems. But we understand why people were doing this hack and we addressed that underlying workflow problem with a new feature that was introduced in 12.1.0.

               

              Before you upgrade you should go into the application package and save your LUTs into another location for safe keeping.  When you upgrade those LUTs will be deleted because they are inside the application package.

               

              Then upgrade to 12.1.1 and install your saved LUTs into the directories explained below.

               

              But there is a big problem you are likely to run into - LUTs that have been applied in previous projects when you were using the hacked application package method will almost certainly have the wrong LUTs applied after you upgrade.  I'm very sorry to say that there is no automatic fix for this.  You will need to go through every clip in your project and reapply the correct LUT.  Using the method explained below will be future proof and you should never have to do this again.

               

              Mac

              1. From the finder, use the Go menu to navigate to this directory: ~/Library/Application Support/Adobe/Common/
              2. Create a folder named LUTs
              3. Create two more folders inside the LUTs folder: Technical and Creative
              4. Copy technical conversion LUTs (often called camera LUTs) such as LOG to Rec709 into the Technical folder
              5. Copy creative LUTs such as day-for-night, B&W, or anything that is just a stylistic look into the Creative folder
              6. Restart PPro
              7. Technical LUTs show up in the Input LUT dropdown inside the Basic section in Lumetri
              8. Creative LUTs show up in the Look dropdown inside the Creative section in Lumetri

               

              Windows equivalent directories:

              ~\AppData\Roaming\Adobe\Common\LUTs\Technical

              ~\AppData\Roaming\Adobe\Common\LUTs\Creative

               

              This is a convenient and easy way to add as many LUTs as you like to the Lumetri dropdown menus and this will persist through updates - unless of course you delete or change this directory.

                Thank you franciscrossman!

                Yeah, I know, but I'm already getting this problem when I send a project to a colleague or when I install new LUT or when I upgrade to the next version of CC.

                 

                 

                Good to know about the new approach (new LUTs folder). But still I have a question: what will happen on CC 12.1.0 when I'll send a project to a colleague? If he has a lut with the same name, it will be applied correctly, even if he has also other LUTs installed?

                 

                Thank you

                  Ah, here is the cool part.  LUTs that are stored in these folders will get embedded into the project file when you use them.  So you can share the project with a colleague and all the LUTs will be present and be functioning for them even if they don't have the specific LUTs installed.  It will not install these LUTs onto the other person's system for them to use on additional clips, however.  It is therefore recommended that you send them the LUT with instructions on how to install it onto their system.  Hope this helps.

                    Past Francis' excellent comments, and from comments at NAB, I think he's one of the people behind the welcomed change ... you can store LUTs and Looks in Library folders. If your Library is shared to other folks in your company and/or project, then they can also have access to them.

                      Wow francis!! This is amazing. Thank you a lot.

                       

                      Nice feature. I think I'll love it if it works as you described.

                       

                      So if I send a project with a LUT on an adjustment layer, my colleague can extend that adj above other clips or just copy and past a Lumetri color effect that has the LUT? Will the LUT be applied to other clips in these ways even if he hasn't the LUT?

                       

                      Thanks

                        Yes, that will work. I'm happy to help

                          And if you have a Library you store your LUTs in, anyone you give access to that Library has full access to those LUTs.
