    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

    Try this:

    thisComp.layer(“Camera 1”).transform.position.speed

    Should have guessed, that makes sense. Thanks!
