This is a 'proof of concept' Movie Maker project, a 5 minute 'linear story' over a 'background'.

(1) For a linear story I whittled down a large transparent image until it worked as a moving title overlay... which kicked into gear at 12,500x480 pixels. Like the wind that you can't see except for its effects, I put a school of fish on the transparent overlay so you could see its motion. Now that I know it works, I can put any assortment of pictures and text on it, and have it go in any direction.

(2) The background clips and music were randomly selected from my library.

As you can see, it's possible. It's not yet practical as a single pass movie, as my computer took 13 hours to save it, almost 13 hours longer than usual for a project of that size and complexity.
