![]() ![]() The rotate mutiplication is awesome to create circle burst animation. Rotate Multiplication is my favorite expression, basically it allows you to rotate multiple shapes around a center point and define how many shape you want this case below is 20 shapes layers until it make a circle. Time expression is good for constant animation, the higher the number next to “time” below the faster your animation will be. Wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime) ĭownload the Loop Wiggle expression example here. Looping wiggle should be seamless and you shouldn’t see a cut, this expression is also used for background animation. The looping wiggle expression become handy when you want an object to move randomly in your composition. loopOut("cycle") ĭownload The Loop expression example here Looping Wiggle (by Dan Ebberts) The Loop expression is probably to most used after effects expression, it allows you to repeat your animationįorever, with code tweak you can also control the loop time and repetitions. X = scale + maxDev*Math.sin(spd*t)/Math.exp(decay*t) ĭownload The Squash and stretch expression example here This bouncing squash and stretch expression should make your animation a bit more alive by adding a proportional scale to your shapes or images. linear(time, marker.key(2).time, outPoint, 0, 100)ĭownload the autofade expression example here Linear(time, inPoint, marker.key(1).time, 0, 100) linear(time, outPoint - tSecs, outPoint, 0, 100) Linear(time, inPoint, inPoint + tSecs, 0, 100) The automatic fade expression is useful when you don’t want to bother a create keyframes for a fade animation. Value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t) ĭownload the AE bounce expression example here. ![]() V = velocityAtTime(key(n).time - ameDuration/10) Just create 2 keyframes position and past the code below.This after effects bounce expression is very useful to make your animations and titles look dynamic with a nice elastic movement, So let’s get to the real stuff, I found most of those useful after effects expressions list below on the web, to me they are the most used expressions unfortunately I don’t remember the ae expression owners name but I am happy to add a name next to those fabulous expressions if you know the programmer please shoot me an email or add a comment. For those who have programmer brain which I don’t have □ After effect Expression can significantly improve your workflow when you create an animation and with complex codes you canĪctually achieve amazing motion graphics. It is amazing that with a few programming codes it can help make your animation moving organically. Over the years I have learn that after effects expressions can be very handy and powerful to make great motion graphics. " tFontSize(thisComp.layer("Null 1").Really quick for those who are new to After Effects so what is an after effects expression ?Īn After Effect expression is a programming Javascript language code that you insert in any “Time-Vary stop watch” by pressing Alt-Click. Sure, I could add a Controller Null layer with an expression Slider control, and then add this in the sourcetext of every layer that use that size, but just like BurgerKing : "I want it my way. What if it's a property of Text directly? Let's see. Maybe I need to specify it's a property of Text? Hmm, that returns "undefined" but no error. Maybe it needs the sourceText property? Nope, no luck either. "FontSize : " + thisComp.layer("Base").style.fontSize I've tried various permutations of the syntax, but no luck. However, when I try to read this property to the Target layer, by using the following on the sourcetext of layer Target, I keep getting an error " Cannot read property 'fontSize' of undefined". When I use the following on the sourcetext of the Base layer, it returns the font size - as expected - in its own layer (of course) : style.fontSize ![]() I'm trying to read the font size of one Text layer ("Base") to another Text layer ("Target"). ![]()
