When I scrub forward vertical lines do not appear on the Timeline When I scrub backwards the vertical lines appear. Adobe and Dell Technical Support tried to fix the problem. They were not successful. I previously tried the suggestions on the Adobe Forum.
Could you post a picture of the vertical lines you're talking about? I need more info to help figure out what's going on.
What computer are you on? Mac or PC? What OS?
What version of Premiere are you on?
What other techniques have you tried to get rid of the vertical lines?
Thanks! Happy to help, just need more info.
