首尔电梯悬疑短片

创作一部**时长恰好为30秒的写实韩国心理惊悚片**，故事发生在现代首尔，时间为凌晨1:30。

**主角：**一名20岁出头的韩国女性，具有自然的韩国人特征、白皙肤色、及肩深棕色头发和柔软刘海，身材纤瘦写实。她穿炭灰色宽大羊毛大衣、黑色针织衫、深色短裙、黑色薄丝袜和黑色皮革短靴。右肩挂着一只黑色小挎包。全片保持外貌、发型和服装一致。

**视觉风格：**真人电影写实风格，真实的首尔公寓室内环境，冷色荧光灯光线、低饱和色彩、反光的电梯墙壁、微妙的胶片颗粒，以及克制的心理恐怖感。表演自然，动作可信。不要CGI、超自然效果、夸张表情或突然惊吓。

**30秒分镜脚本：**

- **0–3s｜到达：**下雨的首尔豪华公寓大堂。疲惫的女子走进来，按下电梯按钮，独自等待。
- **3–5.5s｜陌生人：**电梯门打开。一名穿深色商务西装、沉默的韩国中年男子走进来，站在角落。
- **5.5–8s｜方向错误：**她按下17楼。电梯出乎意料地开始下降。她注意到楼层数字在变化。
- **8–10.5s｜倒影：**她在光亮的墙面倒影中看见男子站在自己身后。她转过身，他却消失了。
- **10.5–13s｜B4：**电梯里空无一人。显示屏上写着B4。她紧张地向后退。
- **13–16s｜地下室：**电梯门打开，外面是一条空荡、灯光惨白的地下走廊。她谨慎地走出去。
- **16–19s｜另一个自己：**走廊尽头站着一名穿着完全相同服装、与她一模一样的韩国女性。她慢慢朝镜头抬起头。
- **19–22s｜通知：**她颤抖的手机特写。安全应用显示：“检测到移动——电梯B4。”
- **22–26s｜未来影像：**监控录像显示她独自在电梯内，没有男子出现。时间戳显示明天凌晨1:30。她睁大双眼。
- **26–30s｜最终反转：**那个一模一样的女人突然靠近许多。灯光闪烁，手机屏幕变黑，身后响起电梯到达提示音。她猛地转身。画面切至全黑。

**声音设计：**雨声、电梯马达声、按钮提示音、门的机械声、脚步声、呼吸声、荧光灯嗡鸣、细微的手机通知音，以及最后一声电梯提示音。没有音乐、旁白、对话或字幕。

**连续性：**每个镜头都保持主角身份、面部特征、比例、发型和服装一致。维持真实的韩国场景、一致的电影调色、自然动作和空间连续性。不要标志、水印、扭曲的脸或多余的视觉效果。

**格式：**时长恰好为30秒，电影画幅16:9，真人实拍写实风格，镜头间无缝衔接，悬疑氛围浓厚。

Create an **exactly 30-second photorealistic Korean psychological thriller** set in modern Seoul at 1:30 AM.

**Main Character:** A Korean woman in her mid-20s with natural Korean features, fair skin, shoulder-length dark brown hair with soft bangs, and a slim realistic build. She wears a charcoal-grey oversized wool coat, black knit sweater, short dark skirt, sheer black tights, and black leather ankle boots. A small black shoulder bag hangs from her right shoulder. Maintain identical appearance, hairstyle, and outfit throughout.

**Visual Style:** Live-action cinematic realism, authentic Seoul apartment interiors, cold fluorescent lighting, muted colours, reflective elevator walls, subtle film grain, and restrained psychological horror. Natural acting and believable movement. No CGI, supernatural effects, exaggerated expressions, or jump scares.

**30-Second Storyboard:**

- **0–3s | Arrival:** Rainy luxury Seoul apartment lobby. The tired woman enters, presses the elevator button, and waits alone.
- **3–5.5s | Stranger:** Elevator opens. A silent middle-aged Korean man in a dark business suit enters and stands in the corner.
- **5.5–8s | Wrong Direction:** She presses floor 17. The elevator unexpectedly begins descending. She notices the changing floor numbers.
- **8–10.5s | Reflection:** She sees the man standing behind her in the polished wall reflection. She turns around, but he has vanished.
- **10.5–13s | B4:** The elevator is completely empty. The display reads B4. She steps backward nervously.
- **13–16s | Underground:** Doors open to a deserted fluorescent-lit basement corridor. She cautiously exits.
- **16–19s | Double:** At the far end stands an identical Korean woman wearing the exact same outfit. She slowly raises her head toward the camera.
- **19–22s | Notification:** Close-up of her trembling phone. A security app displays: "Motion detected — Elevator B4."
- **22–26s | Future Footage:** CCTV footage shows her alone inside the elevator, with no man present. The timestamp reads tomorrow, 1:30 AM. Her eyes widen.
- **26–30s | Final Twist:** The identical woman is suddenly much closer. Lights flicker, the phone turns black, and an elevator arrival chime sounds behind her. She turns sharply. Cut to complete black.

**Sound Design:** Rain, elevator motor, button beeps, door mechanisms, footsteps, breathing, fluorescent hum, subtle phone notification, and one final elevator chime. No music, narration, dialogue, or subtitles.

**Continuity:** Preserve identical character identity, facial features, proportions, hairstyle, and outfit in every shot. Maintain realistic Korean locations, consistent cinematic colour grading, natural movement, and spatial continuity. No logos, watermarks, distorted faces, or unnecessary visual effects.

**Format:** 30 seconds exactly, cinematic 16:9, photorealistic live-action, seamless shot transitions, atmospheric suspense.
