Creative COW Master Series : Advanced Rotoscoping Techniques

[Nguyen Trung Hoa]

Let's face it: rotoscoping is a drag. You can put countless hours of work into cutting elements out from even a few seconds of your footage, and it comes out badly more often than it doesn't. You want to scream and rip out your hair, not to mention kill the guy who shot the footage and said "We'll fix it in post."

But don't sweat it. We've got you covered! VFX and compositing expert Pete O'Connell shows you advanced techniques for rotoscoping in After Effects that will change the way you think about one of the most challenging tasks for any compositor. Pete uses his unique style to show you the tricks he's picked up and created for big-budget Hollywood features including Stranger Than Fiction, The Fountain, Just Like Heaven, Across the Universe, Mr. Magorium's Wonder Emporium, and the highly acclaimed Transporter 2.

Over the course of over 2 hours, you'll learn how to use the entire AE toolset in a whole new way. When it's over, you'll wonder why roto work ever gave you the night sweats.

You'll learn advanced rotoscoping but you don't have to be an advanced AE user to learn these techniques. Pete will show you how to let AE's motion tracker do much of the work for you, how maximize results with expressions, how to set up your comps for the most accurate track, how to find and correct bad roto while you work, how to integrate your masks into your primary footage, and much more.

Beyond roto, you'll learn advanced techniques for precomposition, tracking and stabilization, project organization and keyboard shortcuts to dramatically speed up your work.
