On the Tracks

模型

提示词

Real smartphone selfie video, square 1:1, 9 seconds, one continuous handheld take with the front camera, natural sync sound (wind, distant engines, a burst of engine roar when the cars pass).

CAMERA: a phone held at arm's length by the man himself, slightly above his eye level and tilted, so the whole frame sits at a noticeable diagonal (Dutch tilt of about 20 degrees) with the track curb running from the upper left toward the lower right. His extended right forearm is visible in the bottom-left corner reaching to the lens. Gentle handheld sway and a little wobble throughout, but no cuts, no zoom, no filters. Wide phone lens with a slightly stretched selfie perspective.

THE MAN: a young East Asian man in his twenties, tanned, short dark hair tucked under a plain white cotton cap with a flat brim and no logo, wearing a short-sleeve knit polo shirt with olive-green and black horizontal stripes, plain white cotton shorts, thin white wired earbuds with the cord running down over his shirt, and a silver wristwatch on his left wrist. He fills the upper-left and center of the frame from the chest up, looking straight into the phone with a relaxed, easy smile, teeth showing a little. Calm, natural expressions only.

SETTING: he is standing right on the red-and-white striped rumble-strip curb at the edge of a professional racing circuit, the curb visible under and around him. Behind him, the wide grey asphalt track with a crisp white edge line runs diagonally across the frame. Beyond the track: a strip of green grass, a low chain-link fence, then distant grandstands and trees, all bright and hazy. Bright direct midday sun from behind and to the left, so his long hard-edged shadow falls across the asphalt to the right of him and tilts with the frame.

THE CARS: a pack of five or six modern open-wheel single-seater race cars with wide slick tires, big rear wings and colorful team liveries (one black and orange, one blue, one red, one dark navy, one silver). They are at real scale, small in the frame, far behind him on the track, their wheels on the asphalt, and they pass behind him from the left edge to the right edge at high speed in a tight bunch, slightly blurred by motion, with a short haze of dust and tire smoke drifting behind the last car. They never come near him, never leave the track, and never overlap his head.

STORYBOARD: 0 to 2.3 s, the track behind him is empty; he smiles into the phone, sways a little, adjusts his grip. 2.3 to 5.0 s, the pack of race cars streaks across the track behind him from left to right, one after another, engines roaring; he keeps looking at the phone and grins wider, unbothered. By 5.0 s the last car has exited the right edge and a thin puff of dust and smoke hangs over the track, fading by 6 s. 5.0 to 7.0 s, the track is empty again; he tilts his head slightly and keeps smiling. 7.0 to 8.0 s, he raises his free left hand and touches the brim of his cap, adjusting it, still smiling. 8.0 to 9.0 s, he lowers his hand and keeps grinning at the phone with a light sway.

NEVER: the cars must never be giant, never float, never appear above his head or in the sky, never be cut off at the top of the frame; the shot never levels out; he never stops looking at the phone; no text, logos or graphics; no slow motion; no cuts.

Photoreal, sharp, sunny, candid social-media selfie look.
