Scripts Galore and as Panels in AE8

There's enough AE scripts and expressions floating around to make my head swim, and many of them have gestated at AE Enhancers, the uberforum for scripts, expressions, and presets. Many script and expressions can be freely used, distribute or modified -- nabscripts from Roland Kahlenberg has a good number.

Jeff Almasol is gradually updating his redefinery scripts so they can be updated to work as dockable panels in AE CS3. These will include the DV Rebel Tools and ones for Mark Christiansen’s Studio Techniques book.

Here's a quick summary of scripting resources...

Expressions & Scripting Resources for After Effects

JJ Gifford's Expressions in After Effects is basic but useful. Adobe is already offering a scripting guide for AE 8/CS3 at the Developer Center.

The Help system is a good resource; see the online version, Adobe AE LiveDocs.

Other expression training can be found in books like Creating Motion Graphics With After Effects by Trish & Chris Meyer and Adobe After Effects Studio Techniques by Mark Christiansen, as well as in video training like After Effects Pro: Professional Features by Total Training and After Effects Expressions Series by Harry Franks.

Motionscript is Dan Ebberts' project-based resource for After Effects scripting and expressions (and there is a difference; for the user scripts are push button affairs).

redefinery from Jeff Almasol has a great script library along Scripting Fundamentals.

AE Enhancers is the scripting forum for AE.

Dr. Woohoo specializes in AE<-->Flash integration where Adobe leaves off.

Adobe engineer Bruce Bullis, keeper of the AE SDK, maintains the After Effects API Zone.

More valuable scripts and expressions can be found at: Creative Workflow Hacks who links to Armored Squirrel, colinbraley.com, crgreen.com, Leapfrog Productions, nabscripts, Peter Torpey. Cool scripts by Jeff Almasol are also in The DV Rebel's Guide by Stu Maschwitz.

Update: Harry Franks added a free intro video Expressions 101. to accompany his Toolfarm training set.

After Effects Expression Controls is a 3-parter among others in the podcast series by Aharon Rabinowitz.

Lloyd Alvarez has collection of scripts for AE, including BG Renderer CS3, at his new domain, AE Scripts.

Dave van Brink of QuickTime Music fame (and qt_tools) also has AE scripting nuggets at his blog, omino pixel blog.

Chris Hatton and Michael Cardeiro have some cool tricks and scripts too.

Update 2: the AE Scripts blog was started by Anders Sundstedt.

Update 3: The Chad & Todd Podcast noted The SECRET Demo Palette in After Effects!
