Redraw a clip as pencil on paper. Each frame is rebuilt from its brightness and edges: dark areas become graphite shading, outlines become pencil lines, and the whole frame sits on a toned sheet with visible grain.
Shading and contours
Shading sets how much tone is laid down in the dark parts of the picture. At low values the frame becomes a line drawing; at high values it looks like a fully rendered study. Contours sets the weight of the traced outlines, which carry most of the recognisable detail in motion.
Paper and texture
Paper Color tints the sheet. Warm off-white reads as a sketchbook, gray as newsprint, pale blue as a drafting sheet. Paper Texture scales the grain and stroke noise that break up flat areas.
A drawing on every frame
The stroke and grain pattern changes on every frame, 30 times per second of source time. Hand-drawn animation has the same quality, called boil, because each frame is traced separately and no two tracings line up exactly. Lower Paper Texture for a calmer result where mostly the lines move.
Camera shake and noisy low-light footage add movement of their own to the contours. A stable, well-lit source gives the steadiest lines.
