Thanks, it was a little more complicated than it sounded and there are a lot of things that are never explained in either the help files or in the tip balloons. But I did eventually figure it out.

The shadow feature is OK, but what I would really like is to be able to blur the edges on the overlaid video.

The cropping tool leaves bit to be desired, too. Better would be to draw a marquee around what you want and have it drop out everything else. And expanding the handles to shrink the image is a bit counter-intuitive. It seems this is a great design but very badly documented and with a poor user interface.

I'm getting my money back. Overall, the program sucks,
