http://library.creativecow.net/devis_andrew/AE-Basics-30-The-Write-On-Effect AE Basics - A Creative COW series for new users of Adobe After Effects. Lesson 30: In this tutorial, Andrew Devis demonstrates the "Write-on" Effect in After Effects showing how it works and how paths created in After Effects and other programs can be used to create higher quality animations with the "Write-on" effects than might be produced by simply animating the various properties of the effect. Although not strictly one of the shape layer series, this tutorial does follow on from the previous tutorial looking at creating true spirals in After Effects.
