We're here to help with your After Effects problems, critique your pieces, and sometimes provide a spot of inspiration. So if you wanted to have a wiggle that gradually gets faster and faster: just keyframe the frequency slider from 0 to 100 for example.Don't downvote a relevant submission you simply don't like kindly explain in a comment how it could be improved - anonymous downvotes don't help anybody. With the expression all setup, you can then customise the values of each slider control to whatever you like and more importantly: you can also keyframe these values as well! What this expression does is create a variable for each of the slider controls we created, it then uses these variables for the frequency and amplitude parameters of the wiggle expression. Var freq = effect('Frequency')('Slider') Select the property you want to apply your wiggle to, in this example we’ll select the position, and then Option-Click the little stopwatch icon to open up the expression controls ( alt-click if you’re on a PC). Now we’ve got the two sliders, we can create the wiggle expression and link all the values up. Rename this second slider from Amplitude 2 to Frequency. Once you’ve renamed your first slider, select it again in the Effect Controls Panel and choose CMD+D (or Edit > Duplicate) to duplicate it. In the Effect Controls Panel you should now see the slider control on your layer.Ĭlick on the slider’s name (usually: Slider Control), hit the return key and rename it to: Amplitude.

So to do this, search “Slider Control” in the Effects & Preset panel and then drag and drop it onto your layer. The first step is to create the two slider controls we’re going to link the wiggle expression values to. How to set up your wiggle expression:įor this example we’ll wiggle the position of a 2D text layer. Once the parameters are linked, you can then keyframe your slider controls however you like to create a more dynamic and interesting wiggle. Well, there is a pretty simple way of doing this: all you need to do is link the two wiggle parameters to two different slider controls. So for example, if we had a wiggle expression with the values: wiggle(3,50) - this would mean our wiggle happens 3 times a second, and the value being wiggled would change by plus or minus 50.īut what happens if you need to control the amplitude or frequency of your wiggle expression?

The amplitude value controls the size of the wiggle. The frequency value controls how many times per second the wiggle will occur. In its most basic form, the wiggle() expression needs two parameters: frequency and amplitude (in that order). The After Effects wiggle expression is perhaps one of the most well-used expressions in any motion designer’s toolkit.
