Seedance 2.0 情侣骑薄荷绿踏板车去海边 旅行提示词

SCENE CONTEXT A bright summer afternoon on the coastal road: the young man drives the mint scooter down toward the sea with the young woman riding behind him, arms around his waist — an easy, happy ride past the railway crossing along the water. ACTIVE REFERENCES <<<image_1>>> — young woman, 20 years old, 165 cm tall, slender, straight dark brown hair with side-swept bangs pinned by a small black clip, freckles across her cheeks and nose. 100% matches the reference. <<<image_2>>> — young man, 22 years old, 178 cm tall, lean, sun-tanned, messy dark hair under a tan baseball cap worn backwards. 100% matches the reference. <<<image_3>>> — vehicle: vintage mint-green scooter with a brown leather saddle, chrome mirrors and silver wheels. 100% matches the reference. <<<image_4>>> — location: coastal road curving downhill past a railway crossing with yellow-and-black crossbuck signs, utility poles and wires, stone embankment walls, an orange convex traffic mirror on a pole, the open sea with white-capped waves behind. LOCATION MAP The road from <<<image_4>>> curves downhill through the midground toward the railway crossing, the sea filling the background beyond it. Stone embankments rise on both sides, the orange convex mirror stands on the right shoulder in the near foreground, utility poles line the curve. Their path: down the curve, past the crossing, along the water toward screen-left. Primary light: bright seaside daylight, sun high, wind off the sea. FIRST FRAME AND SPATIAL BLOCKING The first visible frame already contains <<<image_3>>> rolling down the curve with both riders aboard — <<<image_2>>> driving, hands on the grips, <<<image_1>>> seated close behind him, arms wrapped around his waist, her head just above his shoulder, a full head shorter than him. No empty establishing frame, no delayed reveal. He drives in every segment; she is always the passenger. FORMAT MODE Controlled four-segment multi-shot sequence: one INSERT CUT and two HARD CUTS. Real-time motion at an easy unhurried scooter pace. Every segment is shot handheld — no static shot anywhere in the sequence. OPTICS LENS LOCK SEGMENT 1 = 47° diagonal field of view, standard normal lens character, camera 12 to 15 meters at the roadside, the scooter and both riders full in frame with the crossing and sea behind, straight lines rectilinear, no fisheye. Soft vintage lens rendering: gentle edge softness, mild halation in the bright sky and sea glare, even brightness across the whole frame — no vignette, corners stay as bright as the center. This rendering applies to every segment. LENS LOCK SEGMENT 2 = 29° diagonal field of view, short telephoto character, camera 3 to 4 meters tracking alongside from a following vehicle, close two-shot of their faces and shoulders, the sea streaming soft behind them. LENS LOCK SEGMENT 3 = 29°, camera 1.5 to 2 meters, tight insert on her hands clasped at his stomach, the mint body and brown saddle below, road surface blurring past. LENS LOCK SEGMENT 4 = 47°, camera 10 to 12 meters behind the orange convex mirror on the right shoulder, the mirror large in the near foreground reflecting the road, the real scooter passing through the frame and receding along the sea. No drift mid-segment. CAMERA Handheld in every segment with no exceptions — a real operator at the roadside and in a following vehicle: the frame breathes with shoulder sway and soft micro-tremor visible in every second, small late reframes chasing the scooter and easing back; the tracking shot carries gentle road vibration on top of the hand movement; the insert trembles slightly more; the mirror wide breathes slower but never freezes. No tripod stillness, no gimbal smoothness, no stabilization anywhere. On top, the footage behaves like an old film print running through a projector: constant subtle gate weave, faint exposure flicker, occasional tiny dust specks and hairline scratches, image soft and slightly diffused like an aged 16mm print — never sharp, never digitally clean, no vignette or darkened corners at any moment. ACTION TIMING 0.0s to 3.5s — Roadside wide: the mint scooter putters down the curve at an easy pace, leaning gently with the bend; <<<image_2>>> relaxed at the grips, <<<image_1>>> pressed close behind him, her hair and skirt hem streaming in the sea wind; they pass the yellow-and-black crossing signs with the white-capped sea glittering beyond. 3.5s HARD CUT 3.5s to 6.5s — Tracking close two-shot: she rests her chin almost on his shoulder and says something teasing into his ear — lips moving without audible words; he barks a laugh, shaking his head, cap holding snug; she grins wide against the wind, bangs whipping, eyes squinting happily. 6.5s INSERT CUT 6.5s to 8.5s — Tight insert: her hands clasped over his stomach, fingers laced, giving a little squeeze as the scooter sways through a bend; the mint body flexes light reflections, the road surface streams underneath in soft blur. 8.5s HARD CUT 8.5s to 12.0s — Wide past the orange convex mirror: the tiny reflection of the scooter slides across the round mirror in the foreground a beat before the real scooter enters and crosses the frame, unhurried, the two of them small against the vast bright sea; she tips her head back and laughs into the wind as they recede along the coast; the engine putter fades. PHYSICS The scooter carries real combined weight: soft suspension compression over road seams, a gentle lean into each bend with both bodies tilting as one, slight throttle sway she counterbalances by gripping tighter; engine vibration trembles through their sleeves; wind at riding speed streams her hair, his tee and her skirt hem backward continuously with fabric flutter; the sea wind adds gusts; the convex mirror reflection tracks their motion with true optics. LIGHTING Bright seaside daylight only — no artificial light. Aged film print look: the sky and the glittering sea bloom into a soft white-gold haze with visible halation rings, gentle glow hanging in the air, creamy highlights rolling off softly. Faded pastel grade of an old print: lifted milky blacks, warm ivory and honey tones over softened sea blues, the mint scooter body reading as a gentle washed pastel green, the orange mirror and yellow-black signs as warm muted accents — never oversaturated; slightly yellowed whites, low contrast, colors gently washed as if the print has aged for twenty years, heavy visible film grain crawling in every frame, delicate haze. Exposure stays natural across the frame — no added vignette, no darkened edges or corners. The whole image reads as an old 2000s Japanese film discovered on a dusty reel. No crisp modern digital look, no cool color cast. AUDIO SFX only, with the worn texture of an old optical soundtrack — slightly muffled, faint constant hiss: the soft putter of the small scooter engine rising and fading with the throttle, wind buffeting past, waves breaking below the road, gull cries, her bright laugh snatched by the wind, the faint tick of the engine at the far end. No music, no intelligible spoken words, no captions, no score. POSITIVE LOCKS Identities lock 100% to <<<image_1>>> and <<<image_2>>> in every segment — same outfits as their references throughout, her natural 165 cm and his 178 cm with true relative proportions, his cap staying backwards and snug at riding speed in every shot. <<<image_2>>> drives in every segment; <<<image_1>>> rides pillion with her arms around his waist from first frame to last, hands unclasping never. The scooter stays 100% <<<image_3>>> — mint-green body, brown saddle, chrome mirrors — in every shot. Road geography stays consistent with <<<image_4>>> across all cuts: downhill curve, crossing signs, embankments, orange mirror on the right shoulder, sea always beyond the road; travel direction constan
