Cinematic Romantic Comedy Bike Repair Scene

Seedance 2.0 Prompt | Optimized Structure Version
1) Task Objectives
Designed for Seedance 2.0 multi-modal reference workflow, character performance control, camera control, and native audio-visual sync generation.
Priorities: Character identity stability, clear camera movement motivation, accurate comedic facial expressions, clear verifiable continuity of the core prop across three shots.
2) Overall Style
Cinematic realistic texture. Using a romantic movie aesthetic as a visual misdirection, eventually turning into restrained deadpan mechanical comedy. Natural city twilight light paired with warm practical lights. Visual features include: shallow depth of field, slight film grain, realistic wind, realistic hair movement, realistic fabric physics, realistic mist, and ground reflections.
3) Reference Character Lock
Character ID A | Sword Immortal: Use @Image1 for strict identity/clothing reference. 25-30 year old East Asian female. Must maintain: same face, sharp dark eyes, long straight black hair, tall slender build, jade hairpin, white embroidered silk Hanfu, translucent layered sleeves, silver waist ornament, white cloth boots, same silver long sword.
Character ID B | Cyclist: Use @Image2 for strict identity/clothing reference. 25-30 year old East Asian female. Must maintain: same face, brown short ponytail, same proportions, same outfit, same accessories, same bicycle.
4) Scene Setting
Twilight, quiet riverside pedestrian bridge. Continuous elements: wet stone ground after rain, glowing city skyline, warm bridge lights, wind-blown petals, metal railings, ground reflections, slight evening mist, same bicycle. Clear spatial relationships, high-end restrained romance.
5) Shot Design
Shot 1 | 0–5s: Low-angle wide shot, slow dolly-in. Establish twilight bridge space. Same bike in frame. Sword Immortal walks to Cyclist, slowly draws silver sword, then kneels solemnly on one knee. Romantic strings play. Cyclist freezes, eyes widening. Goal: Create strong "proposal" misdirection.
Shot 2 | 5–10s: Cowboy medium shot, slow semi-circular orbit. Sword Immortal stays kneeling. Cyclist stands by bike. Sword floats horizontally between them, glowing softly. Cyclist nervously tidies hair, whispering: "Sister... so sudden?" Sword Immortal stays serious, doesn't reach for her hand, but towards the bike. Background remains continuous.
Shot 3 | 10–15s: Close-up to extreme close-up. Focus shift reveals truth: The sword tip is precisely tightening a loose pedal bolt. A crisp metal "click" lock sound occurs. Romantic music stops instantly. Sword Immortal tests pedal, stands up, says calmly: "Pedal was loose, would've fallen off if you rode fast." Cyclist looks embarrassed: "I thought you..." Sword Immortal raises an eyebrow, answering deadpan: "You thought too much. Repairing the bike." Bike bell rings once. Freeze frame on Cyclist's blushing face and Sword Immortal's deadpan expression.
6) Sound Design
Native sync generation of Mandarin dialogue and ambient sound. Clear logic with sharp emotional contrast. Music: Romantic strings at start, cut instantly at reveal. Ambient: slight wind, bridge background noise, petal rustle, bike metal sounds, natural reverb. SFX: Sword unsheathing, bolt tightening "click", bike bell ring.
7) Global Constraints
Strict 15s total, 16:9 widescreen, 3 clear shots, stable character identities/outfits, clear continuity of props, accurate Mandarin lip-sync, realistic physics, no subtitles.
8) Negative
blurry, bad quality, low quality, low resolution, noisy, jpeg artifacts, watermark, text, error; deformed, mutated, bad anatomy, poorly drawn hands, bad composition, out of frame, disfigured; inconsistent character, changing clothes, face morphing, background shift, glitching cuts, disappearing props
