Somehow I neglected to link to this early last week. If you’re a Final Cut Pro X user you’ll appreciate the package of effects and tools in FXFactory, including Stupid Raisins Block Pop.
Block Pops custom controls give you more capability and customization options for direction, line color, timing, and motion. Among the transitions, 23 are presets, 23 are custom, but included are over 700 animated presets.
FCPX has come of age.
