    Color Key plus RGB curves slowing down computer

    MM1811 Community Member

      Just updated to Premiere CC 7.2.1 and when I use color Key and add RGB curves to a clip my computer shows down to an almost unsuseable level.  Slow is the new normal.

          Moved from the Creative Cloud to the Premiere Pro forum. They will be able to help you here.

            Hello,

             

            I'm sorry your experiencing this problem. Same question as Jim. Are you on Mac?

             

             

            We are aware of the performance issues that were introduced in version 7.2 with certain AMD GPU cards.

             

            We're investigating the problem now.

             

            I know this is not ideal but in the mean time here's a few workarounds:

             

             

            - Revert back to 7.1

             

            - Disable GPU acceleration when using those effects

             

            Here's a list of effects that seem most problematic:

             

            *Fast Color Corrector

            *RGB Curves

            *ProcAmp

            *Edge Feather

            *Lumetri Looks

             

            These effects do not appear hinder the performance in my testing:

            *All Blurs Effects

            *Three Way Color

            *Crop

            *Garbage Mattes

            *Levels

             

            Again, I apologies the the inconvenience.

             

            Best,

              Peter,

               

              I searched for amd gpu stuff, didn't find a "recent" (last month or so) thread. Which amd cards are the ones that have the bigger issues? Do you have a list someplace?

                Thanks for the help.  I can turn GPU off, I'm not reverting back to 7.1.  To many projects I don't want to "hope" aren't effected. Adobe phone support was biggest help, guy took over my computer and reset Premiere by renaming Premiere Adobe preferences folder, which created new folder and basically reset Preimere.  I lost a few saved preferences but it's working much faster.

                 

                On a Mac:  on menu bar Go/ hold down control to make hidden icon Library appear/ preferences/ Adobe/ Premiere Pro/ 7.0

                Rename 7.0 to 7.0_old and relaunch Premiere. 

                 

                Advised not to do this too often but it did work.  Same trick got Media Encoder back from 2 hour export to 5 minutes.
