    Disolve and Opacity issues with CUDA

    Stephen Pickering122 Community Member

      Hi there,

      I thought this was resolved in an update of CS5.5x... I'm running CS6 fully updated.  I CANNOT do a SMOOTH cross disolve or even a gradual opacity change (using keyframes) when I have CUDA enabled.  It's a 1080P 29.97 timeline with a PSD graphic being disolved/faded over top of black (no footage below it).  I'm running CS6 (6.0.5) on Win7 Pro 64.  With Software Only rendering I get perfect disolves and opacity changes.

      Is there a work around?

      Thank you,

      Stephen

          There is no way to change this behavior in that version.  Premiere Pro CC has the option to turn off Linear Color processing with GPU acceleration enabled.

            Thinks Jim.  I know CS6 is one version old, but this is really dissapointing.  A disolve is a basic feature. 

             

            Until then, I found a workable work-around (if doing a fade-in from NOTHING - not a cross disolve between two clips). I had to add my asset (graphic, title, etc.) to my timeline.  Then add a cross-disolve as well as two opacity keyframes (of course, the first at 0 and the second at 100) to match the cross disolve durration.  Then nest the asset (which moves the disolve and keyframes to a nested sequence).  Then add the cross disolve again.  It seems to do what I want it to... just not as easily.

             

            Thanks again Jim for your quick response- it saved me a lot of time of trial and error trying to fix something that can't be fixed.

              OR don't put the PSD on top of black. Put the PSD directly in track 1 and add the dissolves. It then fades smoothly.

              OR put the lens cap on your camera and record some REAL black video. Put that on track 1, your PSD on track 2 and add the dissolves. It then works OK.

               

              You also get the same "not very smooth" dissolves with premiere titles on top of Premiere's black video.
