Yeah, my original suggestion was to do whatever in AE/Premiere or whatver, export some RGBA and use overlay. In this instance pure AVISynth work may have been faster, but the last time I had to overlay something, there were over 60 images and some slightly more fancy stuff that I wouldn't have wasted my time in AVISynth for.
You have to give him his dues though, he found a way round without spamming forums like "hay guyz how do i overlayed titles?"
And :up: for the alternate methods, everyone's a winner.
So now you know I'm more than just a pretty face; I do simple vector hax in photoshop from time to time
