If you’re new to expressions in After Effects, one of the most helpful and easy to use expressions available is the time expression.Essentially, the time expression returns a number value related to your current position in the timeline. if (numKeys > 0){ You can download the After Effects project that contains all of the examples below, including the bird animation HERE. Since this expression is a loopOut, it’s based on the last keyframe moving backward. You can think of them like automated commands that perform specific actions within the layers of your aftereffects composition. Not that kind of expression though. But you can also start building a library of simple expressions like the ones above to be more efficient and give you more creative control over your work. if(n<0) 0 else 100; This script works: If you’ve ever had to create a repetitive movement in After Effects than you’ve probably gone through the painstaking process of copying and pasting keyframes so that they line up perfectly. After Effects Expressions Introduction to After Effects Expressions After Effect is graphics designing software that is used for video editing work and popular between video editing graphics professionals. Note that the magnitude equals the largest distance the layer may travel at once. In order to speed that up, you can add simple math functions, using * for multiply and / for divide. A thoroughly designed course program for motion designers of any skill level. }else{ These modifiers tell After Effects what key frame segments to loop. The most popular bounce expression for After Effects. blinkSpeed=10; freq = 3; This site uses Akismet to reduce spam. The expression below is set with “Null 1” as the layer to connect to. Hi Krystal, sorry unfortunately my after effects can’t save to CS6.

One of the most simple and useful expressions is Wiggle. js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8"; I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language. After Effects expressions are small pieces of code that can be plugged into an After Effects project to achieve a desired effect without using complex keyframing. The automatic fade expression is useful when you don’t want to bother a create keyframes for a fade animation. Basically, expressions can save you a lot of time and give you some cool results that may otherwise be hard to pull off. For the hour hand, we set the expression to time*200/12.

To add an expression or make changes, you’ll want to open the expression controls. One of the most useful applications of an If/Else statement in After Effects is to have an object’s opacity directly linked to another type of value. n = nearestKey(time).index; Some useful After Effects expressions: In this tutorial from Ukramedia, Sergei shows how far a simple line of text can take you in After Effects. This technique works but it certainly isn’t ideal. This bouncing squash and stretch expression should make your animation a bit more alive by adding a proportional scale to your shapes or images. Then when you add the loopOut expression to the rotation parameter, the spinning will continue. if (n > 0 && t < 1){ Expression: loopOut (“offset”); or loopIn (“Offset”); You may already be familiar with the loop expression in After Effects, but you may not be familiar … Today, we’re going to talk about expressions. By adding the same expression and then dividing by 12, we ensure that the minute hand will go around 12 times by the time the hour hand goes around once. layer = thisComp.layer(“Null 1”)layer.toComp([0,0,0]). Before we get started, let’s just cover the basics of using an expression. This will open the expression controls and allow you to paste in or type the code.

In order to limit the wiggle to one dimension, you’ll need to add an extra set of instructions. Argument modifiers tell After Effects which key frame segments to loop. This is a perfect and easy way to create cool dynamic motion in 3D space with 2D layers. Here you can set an initial keyframe for the start rotation and another for the end rotation. In your own version, you’ll replace that with whatever layer you want to attach the end of the line to.

I hope you enjoy it! The Wiggle expression is super handy, but it does affect all of the axes, and sometimes you may only want to wiggle on one axis. Download the project file. 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. Setting the variable to 1 will include 1 keyframe before the last one, 2 will go 2 keyframes back, and so on. offset = 360/(layerCount)*index. You can use the Expression Language menu at any time to insert methods and attributes into an expression, and you can use the pick whip at any time to insert properties. The Loop Expression has three parts namely: property, type and argument modifier; in the format property ("type", modifier).
