    Dissolve flickering

    frogmike Community Member

      Hi, recently when I've been putting dissolve transitions between two clips, some of the clips would start flickering during the dissolve. Its not the video, sometimes when I lengthen or shorten the dissolve, it may go away, but for the most part it still keeps bothering me. Some sort of bug?

          Just to get things started, can you give the details of the Clips (say 1920 x 1080 AVCHD), and also the Sequence settings?

           

          Also, are there any Effects on those Clips?

           

          Last, what version of PrPro are you using, and when you Render the area of the Timline, with the Dissolve Transitions, do you still see the flicker? Does that flicker occur, in Exported footage, or just in the Program Monitor?

           

          Good luck,

            I have it set to DSLR 1280x720 30fps. I do have some minimal effects on the clips. Version 5.0.3 is what it says for my version.

             

            I have everything rendered and it still happens. I've exported the footage and it still transpires there. The flickering is like 3-6 frames of about darkened or lightened 100 pixel vertical bars scattered around.

             

            Checking just now, my footage is 29.97 fps while my sequence was set to 30 fps (to this day I still do not know why it must be so convoluted), I created a new sequence matching the footage, put the footage in and still I received the flickering issue.

            I now also deleted the effects (which are more or less necessary), and the flickering is gone...

              Which Effects please? Any "Auto," like Auto Levels, Auto Color, or Shadow & Highlight, set to Auto?

              Does the Source Footage match that Sequence?

               

              Good luck, and thanks for the info.

                Yeah the footage matches the sequence.

                 

                Shadow/highlights (set to manual), proc amp and levels are mainly the effects used in the effected footage.

                 

                Thanks.

                  If you have MPE hardware on, set it to off and see what happens.

                    MPE? And how would I do that?

                      Ann was referring to the renderer setting and whether it is set to Mercury Playback Engine GPU Acceleration.

                        Mine's selected on Mercury Playback Engine Software Only, I'm not able to select anything else.

                          I've had some problems with flickering in the past and someone on her recommended this and it worked for my problem. Try placing a plain black title underneath the transition. Weird I know, but it worked for my problem a while back. Hope it helps
