STORY: On a bright Southern European street, a young woman hurries with a birthday cake marked by a gold “70” candle. A golden retriever accidentally bumps her; the cake flies forward. A stranger catches it and steadies her. They rush together to a flower-filled outdoor café, where a lonely elderly man is waiting. They surprise him, he blows out the candle, and the dog ends with a tiny dab of cream on its nose. The emotional arc must read clearly without words: urgency → near disaster → spontaneous help → reveal → warm celebration.
EXACT 15-SECOND EDIT AND SHOT PLAN — FAST, CLEAR SHORT-FORM PACING:
0.0–2.6s — HOOK AND GOAL: Immediate forward-moving gimbal shot, camera walking backward in front of the woman as she hurries down a sunny colorful European lane carrying the cake. Begin with a tight cake/candle insert, quickly reveal her face, then she checks her watch and speeds up. Make the gold “70” candle visually clear but do not generate any other text.
2.6–5.4s — INCIDENT: The golden retriever runs gently out from a flower shop and brushes her leg. She stumbles; the cake leaves the tray and moves toward camera. Use a fast whip-pan into approximately 0.5 second of crisp slow motion. The danger is playful and safe, not violent.
5.4–8.3s — SAVE: The man enters from frame right and catches the cake cleanly with both hands while using one forearm to steady the woman. Brief low-angle impact beat, then close reaction: cake intact, both shocked, dog wagging innocently. They exchange a relieved smile. The catch must be visually continuous, not teleportation.
8.3–11.8s — REVEAL: Match-cut into a lively tracking shot as the woman and helper hurry into the adjacent sunlit outdoor café with the cake. Camera passes foreground flowers and pale-yellow chairs, revealing the elderly man sitting alone and looking slightly disappointed. His expression brightens the moment he sees them.
11.8–15.0s — PAYOFF: They set down the cake; the elderly man blows out the “70” candle. Quick warm reaction shot as all three laugh. The golden retriever appears beneath the table with a tiny spot of white cream on its nose. Finish with a gentle crane-up/widening shot through sunlit leaves and hold the complete smiling celebration for the final 0.8 second.
VISUAL DIRECTION: premium naturalistic live-action cinema, bright cheerful warm palette, airy Southern European summer, cream façades, pastel shutters, blue sky, coral flowers, pale-yellow café furniture, healthy natural skin tones. High-key sunlight with soft open shadows, luminous but not overexposed. Warm cream, peach, pale coral, soft sky blue and fresh floral colors. Absolutely no dark, gloomy, desaturated, teal-orange, night, rain, heavy contrast, deep black shadows, or brown vintage filter.
CAMERA AND ENERGY: optimized for mobile short-form storytelling. Strong action in the first second. Use vertical composition with faces, cake and catch centered in the safe middle. Energetic forward tracking, whip-pan, a brief speed ramp, clean low-angle catch, fast match cut, shallow depth through flowers, and gentle final crane. Every 2–3 seconds must introduce a clear story change. Avoid excessive shake and motion blur; actions and facial emotions must remain readable.
AUDIO: sound on. No spoken dialogue and no lyrics. Bright playful acoustic score with light guitar, pizzicato strings and soft hand percussion. Precisely synchronize footsteps, watch glance accent, dog collar jingle, cake whoosh, soft catch impact, café ambience, candle blow, small celebratory chime, and laughter. Music should briefly dip at the cake catch, then lift warmly at the birthday reveal.
QUALITY / NEGATIVE CONSTRAINTS: no face drift, identity swapping, costume changes, deformed hands, extra fingers or limbs, merged bodies, duplicated dog, changing cake, unreadable candle, cake teleportation, impossible catch, aggressive collision, injury, crying, dark lighting, empty dead-looking streets, plastic skin, animation/cartoon style, slow opening, excessive establishing shots, random cuts, malformed architecture, generated words other than the simple gold “70” candle, or ending before the celebration resolves.
AUTONOMOUS EXECUTION: Analyze this complete brief and proceed without asking clarification questions. If the model requires shorter generations, create sequential Seedance 2.0 segments with strict character continuity, then assemble them into one exact 15-second 9:16 final video with coherent audio and deliver the final_video asset.
