![]() ![]() Script source: Motionscript Blink Expression ThisComp.layer(1).position.valueAtTime(time - d)ĭownload the motion trail expression example here Apply to position delay = 5 //number of frames to delayĭ = delay*ameDuration*(index - 1) Motion Trail ExpressionĪs you can see below with this motion trail expression you can get some pretty interesting animation of layers trailing. veloc = 360 //360 Degree Rotation per Secondĭownload The Constant Rotation expression example here. Here is another After Effects rotation expression, no key frames needed to make a simple 360 rotation on a layer. X = position + (time - inPoint) *veloc ĭownload Move Object X Pixel per Second example here Constant Rotation Per Second veloc = 150 //Move object 150 pixel on x axis per second If your tired of making key frames, you’ll like this expression it allows you to move an object on the x axis per second. index*360/20ĭownload The rotate multiplication expression example here. It is a bit complicated to explain how exactly how it work, so feel free to download my file after the animation below. 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. 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. ![]()
