Multiple Movies is an iMovie plugin that allows you to add as many movies (as movie-in-movie) to a clip as you like, allowing you to create an impressive clip show. For each movie you can define a starting position, and ending position. You may also define a size each for starting and ending position. The plug will then calculate all positions and sizes in-between. You may further define (also per movie) when the movie should appear in the clip and when it should disappear. As an option you can tell the plug to calculate replay time of the movie so it fits the time slot exactly.
As an additional feature, this plug also supports pictures (allowing you to mix movies and pictures), pictures with transparency, and animated pictures (e.g. animated GIF).
All plug configuration (i.e. setting up the movie frames) happens in our trademark full-size preview dialog.
