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. Also note that if you do want to use the default values of (“cycle”, 0), you don’t even have to type them in. It’s throwing coded words that perform certain tasks onto your timeline. if (numKeys > 0){ n = nearestKey(time).index; 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. offset = 360/(layerCount)*index. The rotate mutiplication is awesome to create circle burst animation. Ae Expression Source: http://motionscript.com/expressions-lab-ae65/squash-and-stretch.html.

Give this tutorial a try and you’ll be amazed by the simplicity of these expressions. Time expression is good for constant animation, the higher the number next to “time” below the faster your animation will be. I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language. if (n > 0 && t < 1){ Download The Loop expression example here. And if it’s a 3D layer, it will wiggle the x, y, and z axes. n–; The final thing we can add into this expression is an argument modifier. If you don’t want to use all of the keyframes for the loop, set a number counting backward from the end. In motion graphics, we like to keep things moving. The frequency value will affect how fast the layer wiggles and the amount value will affect the magnitude of the wiggle. The second variable is the number of keyframes to include. AE comes with support for expressions, which create relationships between layer properties or keyframes so the designer can animate layers without defining each keyframe by hand. this After-Effects expression. Loop Offset. You can use the key attribute in your After Effects Expressions to work with time, index, and value properties of a keyframe.

Give this tutorial a try and you’ll be amazed by the simplicity of these expressions. Time expression is good for constant animation, the higher the number next to “time” below the faster your animation will be. I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language. if (n > 0 && t < 1){ Download The Loop expression example here. And if it’s a 3D layer, it will wiggle the x, y, and z axes. n–; The final thing we can add into this expression is an argument modifier. If you don’t want to use all of the keyframes for the loop, set a number counting backward from the end. In motion graphics, we like to keep things moving. The frequency value will affect how fast the layer wiggles and the amount value will affect the magnitude of the wiggle. The second variable is the number of keyframes to include. AE comes with support for expressions, which create relationships between layer properties or keyframes so the designer can animate layers without defining each keyframe by hand. this After-Effects expression. Loop Offset. You can use the key attribute in your After Effects Expressions to work with time, index, and value properties of a keyframe.

For the minute hand, we altered the expression to time*200, making it rotate at 200 degrees per second. Amazing After Effects tutorials and templates to improve your motion graphics skills. In your own version, you’ll replace that with whatever layer you want to attach the end of the line to. Wiggle. And the “decay” tells the expression of how much decay to add between bounces. You can simply type loopOut(). Script source: Motionscript. decay = 5.0; Pardon the expression, but you should “work smarter, not harder.” See what I did there? Since this expression is a loopOut, it’s based on the last keyframe moving backward. The “freq” value defines how fast the layer will bounce. We’ve filled them in with numbers to start, but you can change them as needed.
