• CurveConductor brings procedural, curve-driven timing to After Effects. Instead of manually tuning bezier handles per property, you can drive timing across many properties at once with a single control curve. Each control curve exists as a single editable element, and every property that references it updates live when you refine the shape. The result: the beauty of custom curves, without the hassle of ease matching for every property.
