After Effects, scripting and nerdery
I have a copyright notice template and I wanted it to auto update every year. Yes, I’m that lazy. So I should be able to do it with an expression, right? Well, yes… and no.
I have some background elements that I want to wander around, and because I’m lazy I don’t want to hand animate them, so they just have a wiggle expression applied to their position channel and auto-orient switched on. Instant crowd scene! But I want them to have a drop shadow. Normally to keep the drop … Continue reading Auto orienting the drop shadow on an auto-oriented layer
This is a quick run-though of a script I am developing that automates the process of creating a walking character with multiple legs. The script is a bit tricky to use at the moment, and has some flaws, so stay posted for updates. But tricky as it is, it saves a heap of time animating … Continue reading Walker script prototype.
…and this is what it took. Since Adobe removed multi-processing from After Effects I’ve been using the shell to run multiple instances of the aerender application. This can lead to massive performance gains – the screenshot below shows a 4,000% improvement in speed.

It’s a bit like making jigs for woodwork – a little time spent on a jig makes the whole process much easier later on. So here’s a little jig that helps with the sometimes … Continue reading This-n-that – a selection tool

This is a script I should have written years ago. It’s fairly simple; it duplicates the selected layer in a comp, but unlike the built-in duplicate function it creates a new source for the layer in the project, allowing the copy and the original to be independent of each other.
If you want your AE project to access data from an external file to drive expressions you can use the javascript evalFile() function in an expression.
You can use text layers in After Effects as expression editors which means, among other things that a whole lot of layers can use the same expression. This has some big advantages: expressions update as you type, which gives you instant feedback. You can see and edit your expression right in the composition viewer, without … Continue reading Using text layers as expression editors in After Effects
