Adobe's After Effects is the standard software for desktop motion graphics production. This book leads beginning users to more advanced skills for creating professional motion graphics -- high-impact, multielement imagery for film and video. The authors describe how the program works internally, how various features relate to actual program demands, and how to use After Effects tools to solve creative challenges.
This is like the bible of After Effects. It explains so many things (like the AE text animation engine, etc.) that you won't found broken down anywhere else. The Meyers are incredible.
