Can I decrease a Wiggle expression over time?
I have applied a wiggle expression to the rotation parameter on a layer. I need to decrease the total amount of wiggle over time. I know there are probly a lot of ways to do this but i”m blanking out.
Any help would be greatly appreciated!

Search the COW for “wiggle” and “slider”.

Steve’s got ir right. SLiders are a good way to go about with this if you want accuracy. Otherwise, someting crude like this should work too.
//
slowdown1 = index/time;
slowdown2 = 20/time;
wiggle(slowdown1,slowdown2)
//
To slowdown things quicker, instead of time, replace it with (timextime). ANd replace index with any numeral and/or the number 20 with a higher starting number.HTH

Add a null layer and apply two slider controls (frequency and amplitude), then select the values on the wigle expression and link to the corresponding slider control with pick whip, animate the slider. Its work fine

Hi
[RoRK] “slowdown1 = index/time;
slowdown2 = 20/time;
wiggle(slowdown1,slowdown2)”This position expression gives me an division error message!Any hints?

Sorry. My bad. At time zero, you will receive this error message – you can’t divide by zero in as far as Expressions is concerned.
The following should work – I even checked it. 🙂
//
slowdown1 = index/(time+.1);
slowdown2 = 20/(time+.1);
wiggle(slowdown1,slowdown2)
//HTH
