When working with digital video, it is often necessary to place people or objects into virtual scenes, typically by filming the subject in front of a green or blue screen and replacing the background. This process is called "keying," and it can be very difficult and time-consuming. Ultra is a full-featured application included free with Premiere Pro CS3 that aims to make high-quality keying fast and easy. In Ultra CS3 Essential Training, Chad Perkins explores the finer points of keying, as well as how to use Ultra's compositing tools and library of virtual sets and backgrounds. He also discusses how to shoot good footage for keying and how to export the results. Exercise files accompany the course.
Topics include:
- Placing and fine-tuning key points Understanding and suppressing spill Adding overlays and animated backgrounds Customizing virtual sets Creating reflections and shadows Animating virtual camera tracking Keying complex footage Creating HD projects with SD footage Working with audio Increasing Ultra's efficiency
