taming the wiggler
I’ve added the wiggler keyframes to the position poroperty of a composition. This creates a great camera/earthquake shake.
however, what’s the simplest way to smoothly reduce the shake over time so it looks more realistic when at the end of the shake?
That is, the shake begins strong and reduces in intensity over the duration of the “wiggle”.
Cheers,
Gilles

Add a couple Slider Control effects to your wiggling layer. Name one “Frequency” and the other “Amplitude”. Give them the initial values you were using in the wiggle expression. Change your wiggle expression to this:
wiggle(effect(“Frequency”)(“Slider”),effect(“Amplitude”)(“Slider”))
You can easily build that expression with the pick whip….
Then all you have to do is keyframe your Amplitude from, say, 50 to 0 and the thing will stop shaking. (I also use a frequency slider because it’s quicker to change the parameters, especially when I’m using more than one layer with wiggle on it).Ben Unguren

Awesome! Thanks Ben! detailed instructions 🙂
one small issue. in order to make all my layers shake I craeted an adjustement layer above all my layers and applied the wiggle to it’s position property.
I thought this would make everything wiggle but it doesn’t. I do see a “frame” wiggling in the preview (an AE guide, not an actual graphic) so the wiggling is working, my layers just aren’t wiggling.
I thougt an adj layer would work for this instead of pre-comping. what am i doing wrong?

Adjustment layers only work for effects, not for transformations. You could apply the “Transform” effect (I think it is called) and apply wiggle to the position attribute. Or just nest the entire comp in a new one and give it a wiggle….

I see,
thanks for the clarification Ben. I took the pre-comp route and all works perfectly!

BTW, you can also apply the “Sepearate X, Y, Z” Dimensions preset to give you automatic controls that can be animated independently of the wiggler. Just another way of adding additional movement.
Hope this helps!
