This video serves as a little (and I do mean a little) peek on how the scenes in animated shows can change throughout the production process. Believe me, this has not even scratched the surface as to just how deep the process can be. Yes, I know this scene is a tad short, and you might think that it's not worth discussing at all. But as you can see, even the shortest and seemingly unnoticeable seconds still need some serious checking and correcting. (thetvdb.com)
