XEffects is another plugin for Final Cut Pro X (FCP X) that I have found useful for adding more of that polished look to my video projects. The plugin offers 10 or 12 distinctly different transition animations. These transitions are pretty sophisticated and so when you watch them, they feel professional. Not cheesy.

XEffects Tech Transitions is available from idustrual revolution for a reasonable $49.
