Tapering off the ‘Wiggle Expression’…

[Darby Edelen]

[Mark Pybus] “Is there a relatively simple way to taper off a wiggle expression on a camera? “

You can link the frequency and amplitude of the wiggle to slider expression controls (Effect > Expression Controls > Slider) and keyframe them down to 0.


f = thisComp.layer("Control Null").effect("Frequency")(1);
a =thisComp.layer("Control Null").effect("Amplitude")(1);
wiggle(f,a);


In the above code there are 2 slider controls applied to ‘Control Null,’ one is named ‘Frequency’ and the other is ‘Amplitude.’ The values of these sliders define the frequency and amplitude of the wiggle.

Hi Darby,

I’m having a few issues with using the slider to control camera wiggle.

My camera has a wiggle expression attached to position wiggle(.5,20). I’ve created a null and have added a slider to which I have added your expression. When I pick-whip the wiggle expression to the slider I get an error.

Any tips.

Thanks again.
