A vertical short with a twist: in a night park a woman blows out birthday candles and her breath turns into a blast of fire

Prompt

PROMPT:
Using the uploaded person reference image as the sole source of reference for the woman’s identity and outfit, generate a realistic 10-second vertical 9:16 birthday surprise short-form video.

【Style】
The texture of a real smartphone-shot vertical short-form video, in an outdoor park at night.
One locked-off master shot + one face close-up insert. Exactly 2 hard cuts (cut to close-up, return to original composition); no other camera movement. No push, pan, tilt, follow, or digital zoom.
The first half has a soft birthday atmosphere, then abruptly shifts to an exaggerated, intense twist in the second half.
Shots 1–5 are all at natural real-time speed; only the black-and-white segment in Shot 6 is in slow motion.

【Scene】
An outdoor park at night, with a single bench in the center of the frame and a few patches of grass, trees, and streetlights in the background.
At the opening, the bench is empty and the background is simple.
The locked-off master camera maintains the exact same position and composition throughout.

【Woman】
Strictly follow the uploaded image and keep her face, hair, body proportions, outfit, and accessories identical throughout; do not redesign the person. The face close-up and wide shot must show the same face and the same makeup.
She is natural and gentle in the first half.
The core of the twist: her ordinary breath as she blows out the birthday candle transforms into a gigantic jet of fire. Immediately after the slam, she enters the explosive state without pausing and holds an exaggerated highlight pose.

【Key Props】
She always holds the same green champagne bottle in her right hand and the same lit birthday cake in her left hand. From the camera’s perspective, the hand holding the bottle is on the left side of the frame.
The champagne bottle is open. Only real champagne liquid, white foam, and fine droplets come out of the bottle opening.
No fire may come out of the bottle opening, and there must be no fireworks, sparks, cold sparks, silver jets, or magical particles.
The cake stays level, the candle remains lit, and the cake does not tilt, fall, melt, or get scorched.

【Shot 1: 0–3 seconds Establishing the empty bench, entrance, and sitting】
A locked-off camera shows a park bench at night. Show the empty bench briefly at first.
Then the woman enters from the right side of the frame. Holding the green champagne bottle in her right hand and supporting the lit cake in her left, she walks to the center of the bench and sits down naturally. Her body is centered in the frame, and the cake is held steadily near her chest. The camera remains locked off throughout and does not follow her.

【Shot 2: 3–4.5 seconds Shaking the champagne】
The woman grips the neck of the bottle with her right hand and shakes the champagne bottle up and down about three times in a row: raises the bottle to about shoulder height → quickly lowers it to about waist height → raises it again → shakes it down again.
Each movement is driven by her arm and has a clear rhythm, as if building pressure inside the bottle. Her body and the cake remain steady.

【Shot 3: 4.5–5.8 seconds Hard cut to face close-up: sinister smirk】
Hard cut to a close-up of her face. Her face fills the vertical frame, warm streetlight outlines her features, and the night park background is out of focus.
She stops shaking the bottle and gazes into the camera, slowly changing from a gentle expression to a sinister smirk with only one corner of her mouth raised. Her eyes narrow slightly with a crafty glint.
At the end, she takes a big breath as if about to blow out the candle. Her hands remain unchanged below the frame, holding the bottle and cake.

【Shot 4: 5.8–6.5 seconds Return to original composition: slam and candle blowout erupt simultaneously】
Hard cut back to the exact same locked-off composition as Shot 1. The woman remains seated in the center of the bench.
With her left hand, she raises the lit cake in front of her face, slightly below her mouth (toward the right side of the frame). At the same time, she raises the champagne bottle high with her right hand, then quickly swings her arm down and slams the bottle forcefully toward the lower right side of her body (on the left side of the frame from the camera’s perspective). She keeps a firm grip on the bottle neck throughout.
The instant the slam finishes, both effects begin at the same moment, without any pause:
Real champagne liquid, a large amount of white foam, and droplets spray vertically upward from the bottle opening on the left side of the frame;
At the same time, the woman blows hard with her mouth as if trying to blow out the candle — her breath transforms directly into a gigantic orange jet of fire that passes just above the candle and blasts far out toward the right side of the frame.

【Shot 5: 6.5–8 seconds Sustained color highlight spray】
The woman remains seated, continuing to blow toward the candle as she sprays orange fire from her mouth. The flames pass over the candle and extend horizontally toward the right side of the frame. The cake in her left hand stays level in front of her face; the candle remains lit even in the flames, and the cake does not melt or get scorched.
The bottle opening on the left side of the frame continues to spray liquid, white foam, and droplets vertically upward. The flames extend to the right and the fountain to the left — they stretch in opposite directions and do not meet or overlap. No fire ever comes out of the bottle opening.
The champagne must have realistic liquid physics: transparent, pale gold liquid; a large amount of white foam; droplets splashing in all directions; some liquid falling naturally; wet reflections around the bottle opening.
The flames realistically illuminate the woman’s face, outfit, cake, and bench, while the champagne liquid reflects the firelight with warm highlights.
The frame is clearly divided into three zones: champagne liquid and foam on the left, the woman in the center, and the lit birthday cake on the right with orange flames passing above it.

【Shot 6: 8–10 seconds Black-and-white slow-motion birthday poster ending】
At the most exaggerated highlight moment of the spray, on the musical beat, the entire frame instantly hard-cuts to completely unsaturated black and white (no color remains anywhere in the frame) while simultaneously entering slow motion.
The woman continues spraying flames over the candle in exactly the same pose. Champagne foam and droplets drift and fall slowly in black-and-white slow motion, while the flames ripple slowly.
At the exact same moment as the black-and-white transition, white handwritten English text appears at the top of the frame: Happy Birthday. This text must never appear during the color segment.
No pose readjustment, no angle change, no fade, white flash, or dissolve; the transition to black and white must happen instantly.
Slow motion continues to the end, and the final frame freezes on the peak pose for a poster-style ending.
