Reverse Transition Button
Some transition effects have a default direction. For example, a wipe goes from the left
to the right, a clock wipe’s border travels in a clockwise direction, and the spin 3D
transition spins the outgoing clip out to the right.
To reverse the direction of an effect, click the Reverse Transition button. If you reverse
the direction for the above examples, the wipe moves from right to left, the clock wipe
moves in a counter-clockwise direction, and the spin 3D transition spins the incoming
clip in to the left.
