There seems to be new AE training on Lynda.com.
After Effects: Insight into Effects was created and produced by Trish and Chris Meyer. At least part of this seems to have been released a bit earlier, although the tutorials on the Channel filter group may be new. See the previous AEP post Insight into (Blur) Effects for a fuller description.
In the other dated-new title, After Effects CS4 Beyond the Basics, Chad Perkins takes 8 hours to explore techniques for working with motion graphic elements, animation, compositing, color correction, and much more. He provides tips for working more efficiently, using advanced effects, detailed masking and tracking techniques, and expressions. Integrating Photoshop into the After Effects workflow and The Principles of Animation are also highlighted.
