Pickwhip a Rate of Change/position Derivative
on Jul 24, 2014 at 11:39:32 pm

Is there a way to reference the rate of change (as you can see on the speed graph) of an attribute in an expression?

I want to blur a 2D layer by an amount scaled to the speed of the camera, but camera movements are complex and keyframed. I would like to just be able to Pick whip to the speed in the graph editor, but no luck.

Best
Peter

Try this:

thisComp.layer("Camera 1").transform.position.speed

Should have guessed, that makes sense. Thanks!
