## 1. 完整 Seedance Prompt（用户提供范例·英文版）

```
Create a realistic 10-second vertical smartphone video shot by a friend in the stadium stands during a fictional 2030 international football match. China and Brazil are tied 1-1 around the 60th minute. The video feels like a real social-media fan diary clip: handheld iPhone-style vertical footage, slight shake, imperfect framing, loud cheering atmosphere, stadium lights, people brushing past the edge of the frame, red scarves and flags moving in the background. The main subject is the adult Chinese female fan from the provided character card, wearing the same red supporter outfit and China flag face sticker. She is close to the camera, cheerful, playful, and excited, but the mood stays wholesome and celebratory.

Timeline:
0.0-1.0s: The phone camera starts slightly too low and shaky, then tilts up from the red scarves and crowd to find the woman from the character card. Stadium noise and movement are implied visually.
1.0-2.5s: She sees her friend filming and gives a natural quick wave with one hand. Her smile starts small and becomes brighter.
2.5-4.0s: She steps closer through the crowd, hair moving slightly, then does a playful finger-heart near her cheek. Keep the fingers clean and anatomically correct.
4.0-6.0s: A nearby fan briefly crosses the foreground, partially blocking the frame for a moment. When the subject reappears, she laughs and sends a quick blowing kiss toward the phone camera.
6.0-8.2s: She turns her shoulders slightly toward the field, then back to the phone, and forms a two-hand heart gesture. The outfit, face sticker, and hairstyle remain stable.
8.2-10.0s: The camera pulls back a little, revealing more cheering fans and stadium lights. She points toward the pitch, smiles proudly, and keeps celebrating.

Motion and style requirements: vertical 9:16 phone video, candid friend-shot perspective, realistic handheld motion, natural stadium crowd, slight motion blur, imperfect crop, consistent adult character identity, stable outfit, no real sports logos, no sexualized framing, no distorted hands.

## 2. 范式拆解（作为后续 case 的模板 B）

**朋友手机竖屏范式骨架**：

| 段 | 时长 | 设计要点 |
|---|---|---|
| 段 1 · 起手不稳 | 1.0s | 手机太低 + shake → 上抬到主角 |
| 段 2 · 发现镜头 wave | 1.5s | 她看到朋友在拍 → wave + 微笑加深 |
| 段 3 · 走近 + finger heart | 1.5s | 穿过人群走近镜头 + 头发动 + finger heart |
| 段 4 · 路人擦镜头 + 飞吻 | 2.0s | **路人短暂遮挡前景** → 重新出现 → 飞吻 |
| 段 5 · 转身 + heart hands | 2.2s | 转向球场再转回 → 双手 heart gesture |
| 段 6 · 拉远 + 指向球场 | 1.8s | 镜头拉远 → 露出更多观众 → 她指向场内继续庆祝 |

**关键安全护栏**（手机竖屏 vlog 场景）：
- ✅ "handheld iPhone-style vertical footage / slight shake / imperfect framing"——朋友视角真实感
- ✅ "candid friend-shot perspective" + "wholesome and celebratory mood"
- ✅ "stable outfit / consistent adult character identity"
- ✅ "no real sports logos / no sexualized framing / no distorted hands"

**vs 模板 A（转播）的核心差异**：
- A 是"长焦专业转播"——稳定、构图精致、长焦压缩
- B 是"朋友手机抓拍"——手抖、路人擦镜、近距离、亲密感
