Find here the top ten After Effects Expressions that are commonly used by motion graphic designers, you can see the example and download it. If you’re working with Lottie I recommend going as far as to follow them on Github and check the logs, issues and discussions regularly, this is the only place where you’ll get informations (and answers, if you’re lucky)… airbnb/lottie-web/blob/master/CHANGELOG.md # V 5.9. Top Ten After Effects Expression You Must Have In Your Toolbox.
After Effects Wiggle brings your layers to life by altering the speed (the frequency) and the size (the amplitude). After all, very few things in nature stay 100 still or move in perfect, repetitive unison. The only thing is that I never want the number to become 1, only 2 or higher as with 1 the mosaic effect make vertical lines that I dont want. As one of the most popular expressions in After Effects, Wiggle gives randomness to values you apply it to. A wiggle expression in After Effects is a piece of JavaScript code that allow to move,scale,rotate a layer back and forth in a random fashion. In the expression ass two new lines before. Click on the padlock button in the effects Control panel to keep this visible for the next step. To this add two Expression Control sliders, rename one 'frequency' the other 'amplitude'.
That’s not to say no expression are supported, but this one isn’t. I am using the mosaic effect with a wiggle expression on it. Create a new Null called 'Control Layer'. You aren’t missing anything, Wiggle is an expression based effect and isn’t yet supported by Lottie.
