After Effects Brainstorm: Keyframe Variations

Part 3 of our exploration of the Brainstorm module in After Effects.

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.

 
 
(If you missed Parts 1 and 2 of this series on Brainstorm, you can find them here and here.)

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.
