Does anybody know how I can achieve the effect at 00:54, where the ball leaves traces of itself behind it?
I'm assuming that what you must do is mask out the ball in a new layer. And then, using motion track, track where the ball must stay so that it seems that a trace has been left behind.
Please tell me if I'm wrong or if there is a simpler way of doing it thank you!
Yes, very much that. Otehr than that you can always try effects like Echo, CC Time Blend FX, Time Difference etc. to create trails...
