Favorite Expressions I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language. That’s cool with me. Therefore, I’d like to share with you my top 5 after effects expressions. Download My Top 5 After Effects Expressions as FFX presets here. 1. Essentially, Inertial Bounce creates a bouncing motion of any parameter from one keyframe to the next, based on its velocity. This expression is a bit of a community effort. Modify “amp” for the amplitude or how much bounce is present. amp = .1; freq = 2.0; decay = 2.0; 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); value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t); }else{value} Like the free content here? 2. This is nothing brilliant, but it is something I wrote and use all the time. 3. This is a cool expression to use on text. 4.

Motion graphics y diseño generativo En este curso te enseñaré distintas técnicas de animación mediante el uso de expresiones en After Effects. Tus animaciones podrán cambiar de forma, color o movimiento usando sencillos controladores. Parece increíble, pero modificando cuatro ajustes podrás generar distintas versiones de un mismo logotipo de forma fácil en un tiempo récord. ¿Qué incluye este curso? Haremos un breve resumen de las posibilidades que nos brinda el uso de la programación en el terreno gráfico. Veremos sus distintas aplicaciones en el arte generativo, logotipos en sistemas visuales para identidades flexibles, tipografías y también su utilidad en los motion graphics. Daremos una pequeña introducción a la programación con algunos conceptos básicos y sencillos. ¿CUÁL ES EL PROYECTO DEL CURSO? ¿A quién está dirigido? Requisitos La verdad es que los requisitos no son muchos, deberas saber utilizar el After Effects (CS5 o superior), Illustrator o Photoshop. ¿CÓMO FUNCIONAN LOS CURSOS EN DOMESTIKA?

One-sided layers Apply this expression to the opacity attribute and it'll disappear whenever it's flipped away from the camera. You need to have an active camera in your composition for this one to work. a = toWorldVec([0,0,1]); b = thisComp.activeCamera.position - toWorld(anchorPoint); c = dot(a,b)/length(b); if (c > 0) 0 else value Object bouncing on a floor This will make your layer/object bounce along an imaginary 'floor'. Translate 3D coordinates to 2D src = comp("3D Data Comp").layer("3D Layer"); src.to_comp(src.anchor_point); Bouncy scale 'IN' Apply this expression to the 'scale' parameter of your layer. k=16; // final scale a=5; // how quickly the bounce ends b=20; // how many bounces it'll do (that is, the bounce speed) x=k*(1-Math.exp(-a*time)*Math.cos(b*time)); [x,x] Auto Layer Flip [(toCompVec([0, 0, 1])[2] > 0 ? Scale relative to distance from camera Create a comp.

Create Swinging Banner In After Effects - After Effects I’ve seen an effect recently in a few different places that simulates a series of connected cards swinging down and coming to a rest in a very natural way. I went about seeing if I could figure out how this was done. After a few searches on Google I found Dan Ebbert's (the guru of expressions) Pendulum expression. This expression is perfect for this effect as it simulates the exponential decay of a swinging object. Step 1 First up I’ve created three Comps made out of an orange solid and a text layer, one for each word. I’ve aligned them in my main comp so they’re joining and made them 3D. Step 2 Now I’m going to parent the layers using the pick whip. I’ve done this so the layers stick together even when they are individually rotated on the X axis. Step 3 So now I know that’s working I’m going to add the Pendulum expression to my top (Mac) comp. Step 5 Here’s the Pendulum expression found on Dan’s site which is full of useful expression goodies. The expression itself is pretty simple. Step 6

After Effects Expression examples Dan Ebberts provides example expressions and tutorials for learning how to work with expressions on his MotionScript website. For example, Dan provides an excellent page about collision detection. Trish and Chris Meyer provide a series of articles about expressions on the ProVideo Coalition website. These articles contain many useful examples. Colin Braley provides a tutorial and example project on his website that show how to use expressions to make one layer repel others in a natural-seeming manner. The AE Enhancers forum provides many examples and much useful information about expressions, as well as scripts and animation presets. Rick Gerard provides an example on his website that demonstrates rolling a square object along a floor so that the sides stay in contact with the floor plane. Carl Larsen provides a video tutorial on the Creative COW website that demonstrates how to use expressions and parenting to relate the rotation of a set of wheels to the horizontal movement of a vehicle.
