Drop Shadow is a highly effective, fun, and 'tres cool' plug-in for iMovie that lets you float any graphic above your clip - and cast a drop shadow onto the clip's surface. What's so special about 'drop shadow' is that it detects the artwork's shape itself, and draws the drop shadow accordingly. Add to this it's ability to 'gaussblur' the shadow, and controls to specify height and direction of the shadow, and you have one exciting plug-in that'll make Final Cut Pro owners green with envy (and no, this plug does not work with FCP. And yes, we continue our tradition of "ludicruously affordable" prices).
Mac OS X 10.2 or later, iMovie 3.x.
