Do you have trouble remembering which value comes first when setting the Wiggle expression on a layer in After Effects? I used to find myself just trying it to see which value controlled frequency and which controlled the amplitude (how far pixels would move)… And I always got it wrong. From now on, just remember it this way: “Time and Space”. If you’re a Doctor Who fan that’ll be an easy one to remember. Even if you aren’t, you probably heard it once or twice. So, the first value in a Wiggle expression is the frequency (how often) or the time. And the second controls how far the layer will move… in space.
In the graphic: the wiggle is set to 1 then 40. So that’s 1 time per second and 40 pixels movement (through space).
