Trying to re-scale an image down problem

Flash CS3 - I’m trying to create an effect just like the one here:

Note the images of the models seem to move away from the viewer very smoothly - I believe the images are bigger than the stage so that more of the image appears as the image is scaled down…

I’m trying to do this on a much smaller stage size (430x300) and using Transform->Scale and Rotate where I am changing the scale of the image down by 1 percent each time (but not changing the rotation value) - the movie is running at 14 fps but it just looks rubbish and jerky - am I going about this the right way? If not how do I do it and are there any tutorials on this anyone could point me to?

I’m quite new to this so please be gentle - any advice would be fantastic - thanks in advance…
