Wigglin'
by Ari Grunzeweig (Ari) on Mar 22, 2008 at 2:05:27 am

Hi,

I have a simple wiggle expression 'wiggle(20,20)' on the position property of an still image layer in my comp.

Is there a way to have the magnitude of the wiggle decrease over time? Meaning to have it wiggle lots (20 pixels) at the start then decrease to zero at the end?

Thanks in advance!!

Yes! Add an expression control to the layer you want to wiggle.

Effect -> Expression Controls -> Slider Control

In your wiggle expression, highlight one of your parameters and pick-whip the slider control. Now your wiggle parameter is linked to whatever the slider control shows.

The slider control is keyframeable, so you can start your wiggle amount at 20, and have it gradually become zero at a later point in your timeline.

Here are some COW tutorials related to this topic:

Good luck!
