Ae Expression Source: http://motionscript.com/expressions-lab-ae65/squash-and-stretch.html. 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. Expression is a programming language made for after effects similar to Java or HTML for building websites. But it would take a long time to get right. In the expression below, we’ve set the type to “cycle”. Here’s where the Wiggle One Dimension expression comes in. We’ve filled them in with numbers to start, but you can change them as needed. Take our GIF example with the hands of the clock. Check our most viewed blog such as text animation presets, transitions presets , After Effects expressions. if (key(n).time > time){ Note that the magnitude equals the largest distance the layer may travel at once. These modifiers tell After Effects what key frame segments to loop. That’s cool with me. actually achieve amazing motion graphics. Expressions use JavaScript, and you do need some programming knowledge to make the most of them. var js, fjs = d.getElementsByTagName(s)[0]; The Loop Expression has three parts namely: property, type and argument modifier; in the format property ("type", modifier). this is very nice i am very thanks full to you my Dear its relay very good . The expressions below are all covered in the tutorial above and you can simply copy/paste them to your project! There's a lot of amazing features hidden in After Effects to those that aren't familiar with expressions. This is a perfect and easy way to create cool dynamic motion in 3D space with 2D layers. I hope you enjoy it! freq = 3; For movement on the y axis only, you’ll change this section to [value[0],w[1]], and on a 3D layer where you want to wiggle on the z-axis, you’ll use [value[0],value[1],w[2]] instead. Also please like & Share Instead, you can paste in the Inertial Bounce expression on your position property, and adjust the parameters to your liking. As you can see below with this motion trail expression you can get some pretty interesting animation of layers trailing  . Here is the list of After Effects expressions used in this tutorial. For the hour hand, we set the expression to time*200/12. Download the Loop Wiggle expression example here. js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8"; If you want to get serious about it, you can start writing your own expressions to do all kinds of things for you. }(document, 'script', 'facebook-jssdk')); This after effects bounce expression is very useful to make your animations and titles look dynamic with a nice elastic movement. The “freq” value defines how fast the layer will bounce. Simply select the layer you want to work with. 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. For the minute hand, we altered the expression to time*200, making it rotate at 200 degrees per second. For instance, let’s say you want your layer to move back and forth in z space randomly, but not across the x or y-axis. fjs.parentNode.insertBefore(js, fjs); Here is an example of a more complex animation that uses many of the expressions above. this After-Effects expression. Download Move Object X Pixel per Second example here. To do this, we’ll add expressions to the Starting Point and Ending Point controls in the beam effect. It is a bit complicated to explain how exactly how it work, so feel free to download my file after the animation below. We have a more detailed explanation in our post How To Use Templates, Presets, Scripts, & Expressions. In motion graphics, we like to keep things moving. value; The best plugins and scripts for 3D, VFX and motion graphics software including Adobe After Effects, Cinema 4D and Premiere Pro.

Hi, thanks for this scripts it is useful for my animation works also am using this for UI Animations. Download the project file. In order to speed that up, you can add simple math functions, using * for multiply and / for divide. The blinking expression become super handy when you don’t want to repeat a bunch of opacity keyframes over and over or want to animate a cursor quickly. I have AE Cs6 and unable to open any of the files. Not that kind of expression though. He talks about some useful expressions like Value, Time, loopIN(), loopOUT(), wiggle() and more. 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 can blinkSpeed=10; This script gives an error: The basis for the expression below is to allow you to give 3D properties to 2D effects. Amazing After Effects tutorials and templates to improve your motion graphics skills. n = 0;if (numKeys > 0){n = nearestKey(time).index;if (key(n).time > time){n–;}}if (n == 0){t = 0;}else{t = time – key(n).time;}if (n > 0){v = velocityAtTime(key(n).time – thisComp.frameDuration/10);amp = .05;freq = 4.0;decay = 2.0;value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);}else{value;}. Hey, thanks a lot for this great info. } thank you. Download The rotate multiplication expression example here. Having an object or layer wiggle around and look somewhat random is hard to pull off. After Effects (AE) is a great tool for prototyping UI animations, but we’re always looking for ways to speed up our workflow. This type of loop will end at the last keyframe, then start again that the first keyframe in your selected range, and will most commonly be used. Hi Krystal, sorry unfortunately my after effects can’t save to CS6. Time is a variable used in expressions to tell something to move over time with the default being per second. Really quick for those who are new to After Effects so what is an after effects expression ? Setting the variable to 1 will include 1 keyframe before the last one, 2 will go 2 keyframes back, and so on. The expression below is set with “Null 1” as the layer to connect to. With the blinking expression I get a syntax error: Unexpected token ‘else’ Just use Position or Scale element, and while clicking on the keyframe you need to hold alt in order to paste that Expression. n= Math.sin(time*blinkSpeed); v = velocityAtTime(key(n).time – thisComp.frameDuration/10); Download The Constant Rotation expression example here. Editor’s Note: We used the GifGun plugin to create these Gifs directly out of After Effects, and it was a real time-saver. 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. 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. Let’s learn a few ways you can implement them in After Effects. Since this expression is a loopOut, it’s based on the last keyframe moving backward. n–; True to its name, it loops a specific keyframe or series of keyframes in your animation. }else{ You can think of them like automated commands that perform specific actions within the layers of your aftereffects composition. Unfortunately, many of us still fear expressions. MotionIsland Blog is one of the best resource for Motion Designers & Video Editors where you can find free After Effects templates, presets and tutorials.

Today, we’re going to talk about expressions. By default, 0 will account for all keyframes in the set from beginning to end. One of the simplest ways to make use of this is with rotation. Do this by picking the layer property you want to work with and then hold Option on Mac or Alt on PC while clicking on the keyframe (stopwatch) icon. The variables on the expression below are for the type of loop, and how many keyframes to include in the loop. w = wiggle(frequency , amount);[w[0],value[1]]. If you’re new to after effects, we suggest to first watch our introduction and then come back for these expressions. You don’t need typing the number of objects, you just duplicate it (CTRL+D) 1. Over the years I have learn that after effects expressions can be very handy and powerful to make great motion graphics. For more information on GifGun, check out our recent GifGun review. If You want start counting from specific layer, just add “-thisComp.layer(“your layer;”).index” at the end of the line one. I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language. In motion graphics, we like to keep things moving. 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. The loopOut expression is rather simple looking, but it does have a lot of control to it. These are the values related to “amp”, “freq”, and “decay”. Give this tutorial a try and you’ll be amazed by the simplicity of these expressions. You also get a project file to try these expressions. One of my favorite expressions in After Effects is the time expression. help me with one. For those new to After Effects or anyone who hasn’t dug too deep, expressions are bits of code that you can plug into various After Effects layers that, in turn, tell the program to do certain things without you having to hand animate them. Having an object or layer wiggle around and look somewhat random is hard to pull off. If you don’t want to use all of the keyframes for the loop, set a number counting backward from the end. The basic premise of the expression is to allow you to loop an animation without having to continuously add keyframes. 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.

But the Wiggle expression will do it for you with ease. Now, if you’re a moderate user of After Effects like me, expressions seem scary. n=Math.sin(time*blinkRate); In this lesson we'll cover how to use expressions in After Effects. It is amazing that with a few programming codes it can help make your animation moving organically. The final thing we can add into this expression is an argument modifier. Copy the standard bounce expression for After Effects. forever, with code tweak you can also control the loop time and repetitions. For example, if you wanted to have a ball fall from the top of the screen, hit the bottom, and bounce with decaying force until it stopped, you could do this is individual keyframes and the graph editor. Paste my own code into rottation of object and duplicate multiple time: layerCount = thisComp.numLayers; Time expression is good for constant animation, the higher the number next to “time” below the faster your animation will be. 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. 5 Unique Expressions in After Effects. We can animate any object in this software by using Expressions. if(n<0) 0; Argument modifiers tell After Effects which key frame segments to loop. n = nearestKey(time).index; The rotate mutiplication is awesome to create circle burst animation. We set the axis point at the center of the clock for the hands to rotate around. Here you can set an initial keyframe for the start rotation and another for the end rotation. The Loop expression is probably to most used after effects expression, it allows you to repeat your animation Here again, you’ll change out “frequency” and “amount” with numbers to represent the speed and amplitude of movement.
