Motionworks has another video in its CS4 tour, New Features in After Effects CS4: Part 4,
CS4 introduces us to 3 new effects: Cartoon, Bilateral Blur and Turbulent Noise. Bilateral Blur and Turbulent Noise are very similar to the existing Smart Blur and Fractal Noise effects. In this tutorial, we’ll take a quick look at these new effects and see what makes them different.
CS4 product trials are almost ready; you can be notified by Adobe when they're ready. The same gotcha for video is that Adobe trial software doesn't contain the license for some codecs.
