In this After Effects tutorial I show how to animate cog wheels with expressions.
You simply keyframe the rotation of one wheel and all other wheels follow automatically. The shown technique cannot only handle normal chain wheels, but also internal gears and barrels.
For this tutorial we use the After Effects tool iExpressions. It allows to create expressions without the need to write program code. More infos:
Special thanks to Hans-Juergen Steidte for providing the providing the images of the cog wheels used in this tutorial.
