Here's the latest week or so of assorted After Effects tutorials, tips, and scripts & plug-ins new and old.
AE Scripts redesigned their site with a bright new interface and many operational improvements, and has some exciting new product announcements. The Pixel Bender Kernel Accelerator is native AE plug-in which will execute PBK code on the GPU (only kernel .pbk files are supported now, not graphs .pbg files so not all PB plugins will be supported). Also available now is Layer Repeater, a new script which is "like a mini-mograph for AE layers." It's reminiscent of some older 2D plug-ins and the 3D Layer Distributor script. For extra credit, see Motionographer's interview with Lloyd Alvarez for the occasion.
Also announced is a September release of Plexus version 2, which looks to be another must-have upgrade. Here's Lloyd on Pixel Bender and Satya Meka on Plexus 2:
Introducing Knoll Light Factory 3! outlines the massive upgrade for the venerable lens flare plug-in Knoll Light Factory. With extra "believable" flares, new light behaviors, "more realistic scenes", and a host of other features at a reduced price, it's hard to tell if KLF has reached parity or leapfrogged Video Copilot Optical Flares. For background, see Lens Flares in After Effects by Rich Young.
To dig into KLF3, see the 3-part intro Getting Started with Knoll Light Factory 3 by Harry Frank.
Red Giant has a few other items on another recent release in, #69: Depth of Field with Trapcode Mir by Dino Muhic (noted earlier) and Episode 84: Trapcode Mir - Amplitude Mapping.
Need for Speed is commentary by Aharon Rabinowitz on fast OpenGL powered GPU plug-ins like Video Copilot Element3D, Red Giant Trapcode Mir, and Mettle ShapeshifterAE. Many AE users have been envious of Premiere rendering speed for several years, and hopefully the latest excitement will continue. By the way Pixar is open-sourcing OpenSubdiv, technology that is now in Maya; here's Pixar Animation Studios Open Subdivision Technology Review from SIGGRAPH 2012:
Paul Conigliaro noted GM FoldLayers by Goodmotion, a free plug-in (in beta) that "allows you to easily create foldable groups to better organize the layers in your comps." It somewhat satisfies the desires for a subset of features sometimes referred to in requests for layer folders or Ubertwirl (tm). See also AE Scripts' Isolate and especially Zorro-The Layer Tagger. Here's a silent treatment on GM FoldLayers:
In Incorporating Titles/Logos into your footage with After Effects and MochaAE, Josh Weiss talks you through a logo replacement, and leaves the warp matching to you.
Jeff Foster, author of The Green Screen Handbook, is the host of the latest series on Splice Vine, August: Keying / Matting. See also FxGuide's Art of Keying and The Art of Roto, both by Mike Seymour, and Greenscreen and keying resources, 'Super tight' garbage mattes in After Effects, and Rotoscoping tips on AEPortal archive. Here's Best Practices in Software Keying, from Jeff Foster's video2brain course Fundamentals of Compositing, Tracking, and Roto Techniques with After Effects:
