Simple Bounce (Thirds)
A Transition for Final Cut Pro X.
So simple there are no parameters. Drop it on and adjust the length to vary its speed.
(In general, I have a problem with these kinds of effects… well… transition in this case… but it seems to please a lot of people if they don’t have to contribute any effort to their projects … 😀 — I should charge five times the amount just on that principle alone.)
