In the third of our rescued movies on Brainstorm, I demonstrate a much less common use of Brainstorm: to randomize keyframes. Brainstorm can essentially randomize any property you can select in the Timeline or Effect Controls panels - including values that vary over time. In this movie, I create a swarming-style animation by duplicating a layer multiple times, and then using Brainstorm to randomize the intermediate Position, Rotation, and Scale values the layers go through.
The above movie was originally part of our video training course After Effects Apprentice 13: Paint, Puppet, and More. The “and More” part of that course - Brainstorm, and the Cartoon effect - were removed to make room for new movies about the Roto Brush tool. Working with Brainstorm is now covered in the course After Effects Apprentice 04: Layer Control.
