I have 9 video clips from a Robotics match. I want the first 30 seconds of each match to run at 1.5 speed (to help make the overall video shorter). I cut each clip at the 30 second mark of the clip. I adjust the speed of the first part to 1.5. It works. I go to the second clip and cut the first 30 seconds so I can speed it up. No matter what speed adjustment I make the speed adjust dialog looks correct, but the clip does not speed up when played (or previewed in the speed dialog). I try some other clips. They don't speed up either. Only the first one on the track works. I'm using the same very powerfull video editing PC that worked fine on PD13. Windows 10. This is why projects using PD take hours longer than they should!
