PRE 4 or 7
I know how to reverse speed (using time stretch) to make an object appear to rewind. For example... a boat crossing the water from right to left, then stopping and reversing to back up from left to right.
What I want to do is a little different. For example... The boat comes on the screen from the left, but I want it to come onto the screen from the right. I think this would be the equivalent to "filpping" a still photo in PSE. Can it be done with a video in PRE?
