Thanks guys.
I don't see the flicker. Anybody else sees this? Can you give a time where that happens? The pandown is a 2D animation of a premade matte and I didn't manipulate it's brightness in AE, so there shouldn't be any flicker.
@Flynn: By a rough estimate, all the work that went into this clip took about 10 hours. With the crawl and receding logo about 30hrs.
