Hi there, more info necessary. Multiple movies as in tiled? Or overlaid?
Tiled: jit.glue or a more complicated, positioned jit.gl.videoplane setup.
Overlayed: Just about anything that takes in multiple matrices such as jit.alphablend, jit.chromkey, jit.eclipse, etc…
Flash animations are no longer supported by Apple in quicktime, your best bet is to export a non-interactive flash movie as quicktime and use that OR you can publish your flash movie in an html wrapper and use the jweb object custom to the size of your swf. Problem is that you won’t be able to overlay that with standard quicktime movies, it’s one or the other.
