16:9 cinematic demo: Double Dolly.
Technique: A double-dolly-style setup transports subject and camera together, preserving their relative pose while the environment glides past.
Scene: A burgundy-cardigan archivist handles a pale blue map tube in a tall storage room furnished with shelves, a central table and labeled drawers. Paper and fabric have practical, gently worn textures.
Start: Virtual camera level at 1.25 m high, 3.5 m facing the archivist from a shared invisible platform; full figure including both planted feet is visible, tube held at chest, with shelves receding behind.
Motion: Move the shared camera-subject platform backward down the aisle by four metres over eight seconds. Archivist stands still with both feet planted and makes only a small eye movement. Camera-to-face distance and angle stay fixed while shelves pass.
End: Archivist remains identically framed but stands in a new part of the aisle, without having walked.
Camera: 28 mm virtual prime; fixed focal length, f/4, shutter 1/48s, ISO 400, 24fps.
Light: A soft 5000 K source above the worktable gives a cool-neutral key relative to 4300 K white balance. Small 3000 K reading lamps stay warm behind. Flag paper reflections and keep cream labels readable without exposure pumping.
Color: Balance burgundy cloth with muted blue and warm paper. Shadows remain cool charcoal, skin midtones retain subdued warmth, and paper highlights stay ivory with gentle rolloff. Moderate contrast, open blacks and no artificial aged-film scratches.
Duration: 8s. Mode: single_take.
