… to get the Maps, Backgrounds and Animatics in the iMovie 11 browser into FCPX …
most of these 'pictures' are highly complex, tiny 'mini-apps', which calculate the final output.
Create your map in iMovie, export it 'with Quicktime' using proRes and you instantly can use it in FCPX.
and, btw, you find a few of iM's backgrounds in FCPX too, under Generators, e.g. the popular Red Curtain.
