Roto
Silhouette’s Roto allows you to quickly create sophisticated animated mattes using B-Spline, Bézier or X-Spline shapes. Intelligent design and easy-to-use tools, such as variable edge softness on a point by point basis and realistic motion blur, assist you in creating complicated shape animations. Integrated motion tracking makes the normally tedious task of rotoscoping a breeze.
Where did the term Rotoscope come from? A rotoscope was a mechanical device patented by Max Fleischer in 1917. It projected single frames of live action footage onto the animators drawing board. By simply tracing the projected shape, the animator could quickly produce incredibly lifelike drawings. With the passage of time, Rotoscoping or “Roto” for short has become a generic term for drawing shapes to extract, isolate or affect a portion of an image. It is tedious work, but it’s one of the most important parts of the visual effects process.
