Cube Spin transition preview
The "Cube Spin" transition looks like clips A and B are on adjacent faces of a cube and the cube spins from the face showing clip A to the face showing clip B.
This transition has four variations with the following caveat:
Whether you click on the "west to east" or the "east to west" triangle next to the transition preview, you will get a "west to east" transition. To get an "east to west" transition you need to place a check in the "Reverse" checkbox. The same applies to "north to south" and "south to north".
