Start wiggling at time 2 seconds and stop wiggling it at time 4 seconds: timeToStart = 2 Stop wiggling it at time 4 seconds: timeToStop = 4 W = linear(t, 0, loopTime, wiggle1, wiggle2) Wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime) Wiggle(fps,amount,octaves = 1, amp_mult = 0.5,(Math.round(time*fps))/fps) Wiggle +ve only var myWiggle = wiggle(5,100) V Jumpy Wiggle 2 is similar to 1, but works at a defined FPS so your “jump” will happen at a regular pace.

I won’t be able to credit each expression as I have gathered these all in a Word Doc that I have been adding to for years. Most of these expressions I have found or made myself with the help of Dan Ebberts or the Creative Cow forum. I’ve been using expressions more and more over the years and have collected loads of useful and time-saving hacks that help me in my projects, some of these expressions date back to 2006 but still are useful and relevant today. To use an expression, just ALT-CLICK on any parameter that has a stopwatch icon It makes animations and your life easy! It may seem scary if you are new, but trust me, they are so useful and will become your best friend the more you use them and understand them. An After Effect expression is a programming Javascript language code that you insert in
