Felt Tips has a look at using expressions in After Effects to remap time for any animation that can be driven by an effect slider.

In this tutorial, we’ll show how to build an expression that remaps a complex animation to a simple completion sliderFelt Tips – AETuts.com

If that sounds great, thats because it is, but it is just the beginning. He also shows you how to build the expression into a reusable function that you can use in any project, and call it as you would any other After Effects native functions such as toWorld or Wiggle.

Automating tasks becomes important in After Effects workflows, especially if you can create a system or environment where you can easily make changes to a project quickly.

This is why this tutorial is so great. Creating an expression that will allow you to remap time, taking the many keyframes of an animation, and driving the playback through a slider. So essentially you are taking lots of keys and governing them with a few keys – a much better workflow.

Felt Tips mentions that this tutorial is intended for intermediate to advanced After Effects users who are already comfortable using simple expressions and are looking to dive in a bit deeper.
