For the next several movies I'd like to show you how to use the Roto Brush tool,…which was introduced in After Effects CS5.…Roto Brush is a very special paintbrush 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 on the background around it.…If you have access to the Exercise Files, first open Roto Brush 1 Butterfly starter …(RB1-Butterfly*starter).…This is a really simple application of Roto Brush and I want to start with …just to show you some basic concepts.…
In the 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 the 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 will look more realistic if a butterfly …wasn't flying basically below the level of the flowers.…
