Very nice, but you can see what is called a “moire effect” on some of the slides, which is that shimmering from animating fine details. I have read that you can reduce this problem by adding a tiny amount of blur or un-sharpening (Sharpen filter, Amount < 50%). It is not clear whether to put this blur/sharpen filter this before or after the Size and Position. I think it goes before, but that does run much slower than placing it after, which will probably soften the result too much.
