Prompt (original, unmodified)
15秒，竖屏9:16，手机前置镜头质感，轻微过曝+自动对焦偶发虚焦， 深夜台北街头，便利店冷白荧光灯与室外路灯昏黄光冷暖对比， 主角台湾女生【图片1】，低马尾，男友oversized白T恤+短裤，素颜微肿状态。 全程女生单手持机自拍POV，镜头随手腕轻微晃动。 0-4秒：室外深夜，女生举手机对着自己，背景是便利店玻璃门， 她回头确认了一下四周，压低声音凑近镜头比嘘手势； 台词（压低声音、兴奋）："嘘——偷跑出来买宵夜，你不要跟我妈说喔。" 4-9秒：她推门进入便利店，进店提示音响起， 冷白荧光灯骤然打脸，她眯了一下眼，镜头对焦模糊一瞬后恢复； 她走到关东煮柜台前，将手机翻转朝向柜台——镜头对准热气蒸腾的关东煮全景， 停留2秒，再翻回对着自己，她嘴唇微嘟、眼神纠结地看向柜台方向； 台词（纠结碎碎念）："萝卜还是贡丸……算了两个都夹，反正你付钱。" 9-12秒：她端着纸碗推门走出便利店， 便利店白光与路灯昏黄光在她身上形成冷暖交接； [门铃声渐弱+夜晚环境音，无台词] 12-15秒：她换手持机，另一只手用筷子夹起萝卜凑近镜头， 热气飘过形成薄雾，她咬了一口烫到张嘴哈气，随即对着镜头大笑； 台词（被烫含糊，分两拍）："好烫——你先吃！这个萝卜真的绝了！" 禁止出现文字、字幕、LOGO或水印。

How this prompt compares
The techniques this prompt uses are more common in UGC prompts than in the library overall:
| Technique | In UGC | Library average | Lift |
|---|---|---|---|
| handheld | 78% | 24% | 3.22x |
| POV | 21% | 7% | 3.02x |
| close-up | 64% | 40% | 1.6x |
| practical lights | 23% | 12% | 1.81x |

Across all 5,926 prompts, the techniques used here appear at: close-up 40%, wide shot 26%, handheld 24%, warm tone 17%.
The 15s duration is not arbitrary: 71% of the prompts in this library that state a duration ask for exactly 15 seconds — Seedance 2.0 accepts clips up to 15 seconds, so 15s is the model's ceiling and the most common choice.
