Keying, both green/blue chromakey and luma keying. This would be partly a how-to light-and-shoot course, partly screenwork, because lighting for a good key, and shooting usable “plates” is 90 percent of the job. You need to give them some fundamentals so they don’t have to re-invent what already works. Also, how to work with or fix bad footage. Probably the most fun of the segments.
Rotoscoping, and masking and track mattes. Wire/rig removal, image repair.
Color grading and modifying footagee to achieve a specific look. Day-for-night effects. Underwater effects. Dream states. Precipitation FX like snow, rain, sandstorm, fire/smoke. Speed effects, slow-mo, time lapse.
Animating type. Kinetic typography. Advanced graphic design concepts for titling. Animting a virtual camera.
Digital set extensions, digital matte paintings, Integrating CGI with live action plates. Mocap, 3-d tracking and replacing live elements with digital ones. Making 3-d models for pre-visualization, storyboards, animatics.
A person knowledgeable and accomplished at all of these would be a formidable addition to any staff.
I didn’t list VR and stereoscopic, because that should be a separate, high-level course.
