A vertical birthday clip in a bar: a woman in a silver crown blows out a candle and her breath erupts in flame, ending on a black-and-white poster

Prompt

PROMPT:
【Character and Costume Reference】

Use the currently uploaded character styling image as the sole reference for the character’s identity and clothing.
Use the close-up on the left side of the uploaded image to lock in the character’s face shape, features, makeup, hairstyle, and expression; use the full-body front view in the middle and the back view on the right to lock in the clothing construction, jewelry, body proportions, and back styling.

The character’s identity, hairstyle, clothing, jewelry, and body proportions must remain consistent throughout the entire video. No face swapping, outfit changes, hair color changes, or alterations to the clothing construction.

【Style】

A realistic, cinematic short video of a birthday party. The first half has the feel of a natural, understated slice-of-life recording, with a hint of deadpan humor; the second half suddenly escalates into a flame-throwing contrast during the ordinary birthday act of “blowing out the candles”; the video ends directly on a high-contrast black-and-white birthday poster.

The character’s expressions should remain consistent with the quiet, cool, restrained demeanor in the reference image. Do not use exaggerated cartoon expressions.

【Duration / Aspect Ratio】

15 seconds, vertical 9:16.

【Scene】

A birthday gathering in an indoor restaurant or bar.

The female lead sits behind a table, with an elegant round birthday cake placed in the center of the tabletop. The background features dark liquor cabinets, displayed bottles, and warm yellow circular lights. The setting is dim, with soft, warm lighting on the character and cake.

The positions of the tabletop, cake, chair, background lights, and liquor cabinets must remain stable throughout. Do not alter the scene layout.

【Key Props】

Silver birthday crown, round birthday cake, long, thin, curved white birthday candle, lighter.

From being handed in, to being lit by her lips, taken down, and inserted into the cake, the same candle must be used throughout. Its length, color, curved shape, and appearance must not change at any point.

【Camera and Composition】

The camera is fixed directly in front of the female lead, approximately 1.4 meters from her face, maintaining a stable frontal medium shot.

Keep the female lead’s head, face, shoulders, upper body, the area where her hands move, the tabletop, and the entire birthday cake fully in frame, while also retaining part of the background liquor cabinets and warm-colored lights.

No panning, tilting, lateral movement, dollying in or out, or zooming at any point. Any changes in the character’s apparent distance must come only from her natural leaning forward or sitting back, not from the camera changing the shot size.

The first seven shots must play continuously from the same fixed camera position and composition; shot 8 should use the current frame of the fire-breathing climax directly as the black-and-white freeze-frame.

【Shot 1: Putting on the Birthday Crown】

The female lead is already seated behind the table at the start, with the birthday cake sitting steadily in the center of the tabletop.

A hand reaches in from the upper left of the frame, places the silver birthday crown on her head, and naturally adjusts it until it sits securely.

The female lead first watches the hand putting on the crown, then looks forward again. She maintains a quiet, natural expression, with only subtle blinking and breathing. Do not have her start with an exaggerated smile.

The crown must be put on by someone off-screen. She must not already be wearing it at the start, and she must not pick it up herself.

【Shot 2: Holding the Birthday Candle in Her Mouth as if It Were a Cigarette】

A hand enters from the right side of the frame, holding a long, thin, curved white birthday candle and bringing it horizontally to the female lead’s mouth.

The female lead remains seated, with her head facing mostly toward the camera. She naturally opens her mouth and holds the end of the candle nearest her body between her lips, with the other end extending outward.

At the same time, she raises her right hand and holds the candle near her mouth between her index and middle fingers, like holding a cigarette while waiting for it to be lit.

The action sequence must be clear:

The candle is handed in from the right
→ The candle is brought horizontally toward the female lead’s mouth
→ The female lead holds one end of the candle between her lips
→ The female lead steadies the candle at her mouth between her index and middle fingers
→ The hand holding the candle lets go and exits the frame.

The candle must remain horizontal or slightly tilted at this point. Do not hold it vertically or insert it into the cake ahead of time.

This is a birthday candle; only imitate the gesture of holding a cigarette while lighting it. Do not generate a real cigarette, filter, tobacco, smoke, smoking, or exhaling smoke.

【Shot 3: Lighting the Candle at Her Mouth as if Lighting a Cigarette】

The female lead continues holding the long candle at her mouth and pinches it near her lips between her index and middle fingers, maintaining a pose as if waiting for it to be lit.

Another hand enters from the left side of the frame, holding a lighter. The lighter moves toward the exposed end of the candle, away from the female lead’s mouth.

The off-screen person presses the lighter. A flame appears and is brought close to the exposed end of the candle, as if lighting someone’s cigarette, until the birthday candle catches fire.

The action sequence must be clear:
The female lead holds the candle in her mouth and steadies it between two fingers
→ The lighter enters from the left
→ The lighter moves to the exposed end of the candle
→ The lighter’s flame appears
→ The flame touches the end of the candle
→ The candle catches fire
→ A small, steady flame forms at the tip.
During the lighting, the female lead maintains a perfectly composed, calm expression and naturally watches the lighter and flame near her mouth, creating a subtle contrast.
The lighter must only be used to light the candle held at the female lead’s mouth. Do not use it to light the candle on the cake, and do not let it burn her lips, fingers, hair, or face.
【Shot 4: Removing the Same Candle That Was Just Lit】

Once the candle catches fire, the hand holding the lighter immediately exits the frame.

The female lead continues holding the candle between her index and middle fingers and naturally pulls it out from between her lips, as if taking a newly lit cigarette from her mouth.

The action sequence must be clear:

The candle is lit at her mouth
→ The lighter exits the frame
→ The female lead parts her lips
→ She removes the candle from her mouth, holding it between her fingers
→ She raises the lit candle to chest level
→ She briefly looks at the small flame at the tip
→ Her gaze naturally shifts to the cake on the table.

It must remain the same long, thin, curved birthday candle throughout. The candle must not jump between frames, disappear, become shorter or straight, break, or change appearance.

【Shot 5: Inserting the Candle into the Cake】

The female lead holds the same lit candle in her right hand and naturally lowers it from chest level to above the cake.

Clearly show the complete action:

The candle is lowered
→ The bottom of the candle touches the top of the cake
→ The female lead inserts the candle into the cake
→ Her fingertips adjust the candle’s angle
→ Once it is stable, she releases it with her right hand.
Once inserted, the candle must retain its original long, thin, curved shape, and the flame at the tip must continue burning normally.
Do not have the candle appear in the cake out of nowhere or pass directly through it. The cake must not collapse, shift, or deform when the candle is inserted.
【Shot 6: Leaning Forward to Prepare to Blow Out the Candle】
The female lead withdraws her right hand, sits upright again, and rests both hands naturally on either side of the tabletop.
She first looks down at the candle flame on the cake, and a natural, restrained smile appears at the corners of her mouth. Then she begins to lean her upper body naturally toward the cake, gradually bringing her face closer to the candle.
The action sequence must be clear:

She looks at the candle flame
→ Both hands rest on either side of the tabletop
→ She naturally leans toward the cake
→ Her face gradually approaches the candle
→ Her lips purse as she gets ready to blow out the candle.

The female lead always faces the cake and the camera. Do not turn her head from side to side. The camera remains fixed; any natural enlargement of the character in frame must come from her leaning forward.

The candle flame continues to burn steadily and must not go out prematurely.

【Shot 7: Suddenly Breathing Fire While Blowing Out the Candle】

Strictly continue from the previous shot’s forward-leaning pose as she prepares to blow out the candle.

The female lead faces the cake, purses her lips, and begins blowing forward as if normally blowing out a birthday candle. At the exact moment she starts to blow, instead of ordinary airflow, a powerful, continuous stream of realistic orange-yellow fire suddenly shoots from her mouth.

The action sequence must be clear:

She leans forward toward the cake
→ She looks at the candle
→ Her lips purse
→ She begins to blow
→ Fire suddenly appears at her mouth
→ The fire continues spraying above the cake and toward the camera
→ The female lead holds the climactic pose of leaning forward and blowing out the candle.
Fire requirements
The fire can only emerge from the center of the female lead’s mouth;
The fire must be triggered by the blowing action and must not appear early;
The fire must travel in the same direction as the female lead’s breath;
The fire shoots straight forward from her mouth and passes slightly over the cake;
Do not have the female lead lift her head to breathe fire, sit upright while breathing fire, or turn to breathe fire to either side;

The fire must continue to spray, not just appear as a brief fireball;

The center of the fire is bright yellow, with orange-red edges;

It has realistic curling, flowing movement, trailing flames, and slight heat distortion;

The firelight naturally illuminates the female lead’s face, hair, crown, clothing, the tabletop, and the cake;

The surface of the cake and tabletop show realistic warm reflections;

The fire must not completely obscure the cake, burn the cake, or cause the cake or candle to melt or deform;
The fire must not cause the female lead’s mouth, teeth, face shape, hair, or features to deform.
The female lead maintains the pose of leaning forward with both hands braced on either side of the tabletop. She must not suddenly sit upright, lean back, stand up, or change her pose because she is breathing fire.
The cake remains stable in the center of the tabletop, with the curved birthday candle still inserted into it. Once the fire appears at her mouth, the candle’s small flame may be obscured by the strong airflow and fire, but the cake and candle themselves must not disappear.
While breathing fire, the female lead’s expression remains calm and restrained, creating an absurd contrast. Do not make her look frightened, fierce, roll her eyes, or strain excessively.

【Shot 8: Freeze-Frame as a Black-and-White Birthday Poster While Breathing Fire】

When the female lead holds the forward-leaning pose of blowing out the candle and the fire from her mouth reaches its longest, fullest, most impactful moment, use the current frame directly as a black-and-white birthday poster freeze-frame.

人物表情整体延续参考图中的安静、清冷、克制气质，不使用夸张卡通表情。

【时长／画幅】

15秒，9:16竖屏。

【场景】

室内餐厅或酒吧的生日聚会场景。

女主坐在桌后，桌面中央放置一个精致圆形生日蛋糕。背景为深色酒柜、酒瓶陈列与暖黄色圆形灯光，环境偏暗，人物与蛋糕受到柔和暖色光照。

桌面、蛋糕、座椅、背景灯具和酒柜位置全程保持稳定，不改变场景结构。

【核心道具】

银色生日皇冠、圆形生日蛋糕、细长白色弯曲生日蜡烛、打火机。

从递入、嘴边点燃、取下到插入蛋糕，必须始终使用同一根蜡烛，其长度、颜色、弯曲形态和外观不能中途改变。

【摄影机与构图】

摄影机固定在女主正前方，镜头距离女主面部约1.4米，保持稳定正面中景。

画面完整拍到女主头顶、脸部、肩部、上半身、双手活动区域、桌面和完整生日蛋糕，同时保留部分背景酒柜与暖色灯光。

全程不摇镜、不俯仰、不横移、不推拉、不后退、不变焦。人物远近变化只能来自女主自身自然前倾或回正，不能由摄影机制造景别变化。

前七个镜头在同一固定机位和构图下连续完成；镜头8直接使用喷火高潮的当前画面进行黑白定格。

【镜头1：戴上生日皇冠】

开场女主已经坐在桌后，生日蛋糕稳定放在桌面中央。

画面左上方伸入一只手，将银色生日皇冠放到女主头顶，并自然调整至稳定位置。

女主先用眼神观察正在戴皇冠的手，随后重新看向前方。她保持安静自然的表情，只有轻微眨眼和呼吸变化，不要一开始就夸张微笑。

皇冠必须由画外人物戴上，不能开场已经戴好，也不能由女主自己拿起皇冠。

【镜头2：像叼烟一样含住生日蜡烛】

画面右侧伸入一只手，拿着一根细长白色弯曲生日蜡烛，将蜡烛横向送到女主嘴边。

女主保持坐姿，头部基本正对摄影机。她自然张开嘴，将蜡烛靠近身体的一端叼在双唇之间，蜡烛另一端向外伸出。

女主同时抬起右手，用食指和中指夹住嘴边的蜡烛，手势像夹着香烟等待点火。

动作顺序必须清楚：

右侧递入蜡烛
→ 蜡烛横向靠近女主嘴边
→ 女主将蜡烛一端叼住
→ 女主用食指和中指夹稳嘴边蜡烛
→ 递蜡烛的手松开并退出画面。

蜡烛此时必须保持横向或略微倾斜，不能竖直举起，也不能提前插进蛋糕。

这是生日蜡烛，只模仿叼烟点火的动作形态，禁止生成真正的香烟、滤嘴、烟草、烟雾、吸烟或吐烟内容。

【镜头3：像点烟一样点燃嘴边蜡烛】

女主继续将细长蜡烛叼在嘴边，并用食指和中指夹住靠近嘴唇的位置，保持等待点火的姿势。

画面左侧伸入另一只手，手中拿着打火机。打火机移动到蜡烛远离女主嘴部的外露末端。

画外人物按下打火机，火苗出现，并像给人点烟一样，将火苗贴近蜡烛外露的一端，直到生日蜡烛成功点燃。

动作顺序必须清楚：
女主叼住蜡烛并用双指夹稳
→ 打火机从左侧进入
→ 打火机移动到蜡烛外露末端
→ 打火机火苗出现
→ 火苗接触蜡烛末端
→ 蜡烛成功点燃
→ 顶端形成稳定的小火苗。
点火过程中，女主保持一本正经、冷静配合的表情，眼神自然观察靠近嘴边的打火机和火苗，形成轻微反差感。
打火机只能点燃女主嘴边叼着的蜡烛，不能直接去点蛋糕上的蜡烛，也不能烧到女主嘴唇、手指、头发或脸部。
【镜头4：取下刚刚点燃的同一根蜡烛】

蜡烛成功点燃后，拿打火机的手立即退出画面。

女主仍用食指和中指夹住蜡烛，像从嘴边取下刚点燃的香烟一样，将蜡烛从双唇之间自然抽出。

动作顺序必须清楚：

蜡烛在嘴边被点燃
→ 打火机退出画面
→ 女主双唇松开
→ 手指夹着蜡烛从嘴边取下
→ 女主将点燃的蜡烛举到胸前
→ 短暂观察蜡烛顶部的小火苗
→ 视线自然移向桌面蛋糕。

必须始终是同一根细长弯曲生日蜡烛。蜡烛不能跳帧、消失、缩短、变直、折断或更换外观。

【镜头5：将蜡烛插入蛋糕】

女主右手握住已经点燃的同一根蜡烛，将其从胸前自然下降到蛋糕上方。

完整表现以下动作：

蜡烛下降
→ 蜡烛底部接触蛋糕顶部
→ 女主将蜡烛插入蛋糕
→ 指尖调整蜡烛角度
→ 确认稳定后松开右手。
蜡烛插入后仍然保持原有的细长弯曲形态，顶部火焰继续正常燃烧。
禁止蜡烛凭空出现在蛋糕中，禁止蜡烛直接穿透蛋糕，禁止蛋糕因插入动作发生塌陷、位移或变形。
【镜头6：俯身准备吹蜡烛】
女主收回右手，重新坐正，双手自然落在桌面两侧。
她先低头看向蛋糕上的蜡烛火焰，嘴角出现自然、克制的微笑。随后上半身开始朝蛋糕方向自然前倾，脸部逐渐接近蜡烛。
动作顺序必须清楚：

看向蜡烛火焰
→ 双手落在桌面两侧
→ 身体自然向前靠近蛋糕
→ 脸部逐渐接近蜡烛
→ 嘴唇收拢，进入准备吹蜡烛的状态。

女主始终面向蛋糕和摄影机，不左右转头。摄影机保持固定，人物在画面中自然变大只能来自身体前倾。

蜡烛火焰继续稳定燃烧，不能提前熄灭。

【镜头7：吹蜡烛时突然喷出火焰】

严格承接上一镜头的俯身吹蜡烛姿势。

女主面向蛋糕，嘴唇收拢，开始像正常吹生日蜡烛一样向前吹气。就在她正式吹气的瞬间，嘴部没有吹出普通气流，而是突然喷出一道真实、强烈、连续的橙黄色火焰。

动作顺序必须明确：

身体前倾靠近蛋糕
→ 眼神看向蜡烛
→ 嘴唇收拢
→ 开始吹气
→ 嘴部突然出现火焰
→ 火焰持续向蛋糕上方与镜头前方喷射
→ 女主保持俯身吹蜡烛的高潮姿势。
火焰要求
火焰只能从女主嘴部中央出现；
火焰必须由吹气动作触发，不能提前出现；
火焰方向必须与女主吹蜡烛的方向一致；
火焰从嘴部向正前方喷出，并略微掠过蛋糕上方；
不能要求女主抬头喷火，不能坐直喷火，也不能转向左右喷火；

必须持续喷射，不能只是一个短促火球；

火焰中心明亮偏黄，外缘为橙红色；

具有真实翻卷、流动、尾焰和轻微热浪扰动；

火光自然照亮女主面部、发丝、皇冠、服装、桌面和蛋糕；

蛋糕表面与桌面出现真实暖色反光；

火焰不能完全遮住蛋糕，不能烧毁蛋糕，不能导致蛋糕和蜡烛融化或变形；
火焰不能导致人物嘴部、牙齿、脸型、头发或五官变形。
女主始终保持双手撑在桌面两侧、身体前倾的吹蜡烛姿势，不能因为喷火突然坐直、后仰、站起或改变动作。
蛋糕始终稳定放在桌面中央，弯曲生日蜡烛仍插在蛋糕上。嘴部火焰出现后，蜡烛上的小火苗可以被强烈气流 and 火焰覆盖，但蛋糕与蜡烛本体不能消失。
喷火时，人物表情依然保持冷静、克制，形成荒诞反差感，不能惊恐、狰狞、翻白眼或过度用力。

【镜头8：吹蜡烛喷火的黑白生日海报定格】

当女主保持俯身吹蜡烛姿势、嘴部火焰达到最长、最完整、最有冲击力的瞬间时，直接使用当前画面进行黑白生日海报定格。
