Basic Roto Brush setup
- [Instructor] For the next several movies I'd like to show you how to use the RotoBrush tool which was introduced in After Effects CS5. RotoBrush is a very special paint brush that looks for the edges of objects in a layer and separates these elements from each other by creating an alpha channel that basically separates a foreground object from the background around it. If you have access to the exercise files first open rotobrush1 butterfly starter. This is a really simple application of RotoBrush that I want to start with just to show you some basic concepts. In this scene I have some footage of tulips in the background and a little animation of a butterfly flying across the scene in the foreground that we created in an earlier After Effects Apprentice video lesson. I'll render up a quick RAM preview here. And you'll see that our butterfly wafts in front of the flowers. Well that's kind of nice but to be honest I think it'd look more realistic if the butterfly wasn't flying…
