cmiVFX – Introduction to Rotoscope with Silhouette Roto and Paint
Another video training that I’ve produced is online on the cmiVFX website:
This time I worked on a rotoscope training covering the Roto Node of Silhouette Roto and Paint software.
Silhouette is my favorite rotoscope software, and I present not only software skills but also the needed rotoscope techniques to create great mattes.
User Interface tour and overview, learn how to setup projects, sessions, and load media files. Explore the user interface layouts and performance settings that will affect footage playback and rotoscope speed.
Extensive explanation about Silhouette’s shape types: b-splines, x-splines and bézier. Drawing techniques, using the reshape tool, adjusting curve tension and point modes: cardinal, corner, b-spline and center. Navigating the viewer with tools and shortcuts: zoom, pan.Intro to Rotoscope
In depth review of the Project window. Discussion of strategies to break down subjects into shapes for rotoscope. Working with the Viewer modes and inputs to help on shape drawing, rotoscope evaluation and to avoid background color contamination.
Using the reshape and transform tools to manipulate shapes: moving, rotating, scaling, skewing, and corner pinning. Setting the anchor point and using special transform tool modes to manipulate groups of shapes and points. Planning the animation, optimal keyframe positioning in time and dealing with keyframing interpolation. Introduction to the “back and forth” technique.
Review of the Object List: creating and manipulating layers. Techniques to create and use Silhouette’s excellent point tracker. Applying 1, 2 and 4 point tracking data to layers, refining problematic trackers, manipulating the transform matrix of layers and using the layer stabilization feature.
Use of Silhouette’s Planar tracker. Evaluating the planar tracker results. Pre-processing plates to improve planar tracker results. Extracting point trackers from shapes.
Finishing the Rotoscope
After learning the tracking techniques, the rotoscope continue and the project is finished. Discussion of other useful rotoscope techniques, tips and tricks: Using the Multiframe tool, animating shape opacity, layer stabilization, extracting trackers from shapes, breaking keyframed shapes into smaller pieces.
How to deal with hair and other thin rotoscope subjects. Working with open shapes and stroke width. Open shapes drawing techniques, and manipulating/animating complex groups of shapes.
Rendering the mattes to be used on any compositing software. Discussion of render settings and node parameters that affect the render output. Rendering Slap Comps for previews and dailies.
How to export shapes from Silhouette. Detailed export/import overview to After Effects, Nuke and Shake. Using Silhouette Actions.
