# 影视镜头语言 prompt 框架
|
||
|
||
> **何时 read**：影视分镜生图时——按六维度组装 prompt，每张图选 3-5 个维度起作用即可。
|
||
> **配套阅读**：视觉风格库 + 媒介风格锁走 `visual-styles.md`；角色卡 / 多视图布局走 `character-sheet-formats.md`。
|
||
|
||
生成分镜或剧照风格图时，按六维度组装 prompt，每张图选 3-5 个维度起作用即可。
|
||
|
||
## 六维度槽位
|
||
|
||
### 1. 景别（Shot Size）
|
||
|
||
| 中文 | 英文关键词 | 用途 |
|
||
|---|---|---|
|
||
| 大远景 | extreme wide shot, establishing shot | 交代环境 |
|
||
| 远景 | wide shot, full shot | 人物 + 环境 |
|
||
| 中景 | medium shot, waist-up | 对话、动作 |
|
||
| 近景 | medium close-up, chest-up | 情绪 |
|
||
| 特写 | close-up, face fills frame | 细微表情 |
|
||
| 大特写 | extreme close-up, eye / detail | 戏剧张力 |
|
||
|
||
### 2. 机位 / 角度
|
||
|
||
- 平视 `eye-level shot` —— 中性
|
||
- 仰拍 `low angle, looking up` —— 强大、压迫、英雄感
|
||
- 俯拍 `high angle, looking down` —— 弱小、孤独、客观感
|
||
- 鸟瞰 `bird's eye view, top-down` —— 抽离、命运感
|
||
- 荷兰角 `dutch angle, tilted frame` —— 不安、混乱
|
||
- 过肩 `over-the-shoulder` —— 对话主观感
|
||
|
||
### 3. 运镜暗示（静态图怎么表达运镜）
|
||
|
||
静态图无法真"运镜"，但可暗示运镜后的瞬间：
|
||
|
||
- 推镜后瞬间 → `intimate close framing, subject fills foreground`
|
||
- 摇镜中段 → `motion blur on edges, subject slightly off-center`
|
||
- 跟镜 → `subject in motion, camera at same speed, sharp subject + blurred background`
|
||
- 升降镜 → `tilted vertical perspective, sense of rising / falling`
|
||
|
||
### 4. 光影
|
||
|
||
| 风格 | 关键词 |
|
||
|---|---|
|
||
| 伦勃朗光 | Rembrandt lighting, triangle of light on cheek |
|
||
| 分割光 | split lighting, half face in shadow |
|
||
| 边缘光 | rim lighting, backlight outlining subject |
|
||
| 顶光 | top lighting, harsh shadow under eyes |
|
||
| 实用光源 | practical light, lamp / window / neon as motivated source |
|
||
| 体积光 | volumetric light, god rays, atmospheric haze |
|
||
|
||
### 5. 情绪
|
||
|
||
- 紧张：`high contrast, low key lighting, claustrophobic framing`
|
||
- 抒情：`soft diffused light, pastel palette, slow motion feel`
|
||
- 孤独：`negative space dominant, single subject, cool palette`
|
||
- 温馨：`warm golden tones, soft window light, family setting`
|
||
- 悬疑：`shadows obscuring face, fog / smoke, single light source`
|
||
- 史诗：`epic scale, wide composition, dramatic sky, low horizon`
|
||
|
||
### 6. 时间 / 光线时段
|
||
|
||
| 时段 | 关键词 |
|
||
|---|---|
|
||
| 黄金时刻 | golden hour, warm low sun |
|
||
| 蓝色时刻 | blue hour, twilight, ambient blue tone |
|
||
| 正午 | high noon, harsh overhead sun, short shadows |
|
||
| 夜景 | night scene, available light, neon / moon as key |
|
||
| 黎明 | dawn, soft pink-orange sky, low contrast |
|
||
|
||
## Prompt 组装模板
|
||
|
||
```
|
||
<景别>, <机位>, <主体描述>, <场景描述>, <光影>, <情绪>, <时间>, cinematic still, anamorphic lens, 35mm film grain, 2.39:1 aspect ratio
|
||
```
|
||
|
||
示例（紧张/夜戏）：
|
||
|
||
```
|
||
medium close-up, low angle looking up, weary detective lighting a cigarette, rain-soaked alley with neon reflections, rim lighting from neon sign, tense suspenseful mood, night scene, cinematic still, anamorphic lens, film grain, 2.39:1
|
||
```
|
||
|
||
示例（抒情/黄金时刻）：
|
||
|
||
```
|
||
medium shot, eye-level, young couple sitting on a hilltop bench overlooking the valley, golden hour low sun behind them creating rim light, warm soft palette, intimate hopeful mood, golden hour, cinematic still, anamorphic lens, subtle film grain, 2.39:1
|
||
```
|
||
|
||
示例（史诗/远景）：
|
||
|
||
```
|
||
extreme wide shot, low angle, lone warrior on a vast salt flat at twilight, dramatic stormy sky filling 70% of frame, blue hour ambient light, sense of awe and isolation, cinematic still, anamorphic lens, subtle grain, 2.39:1
|
||
```
|
||
|
||
## 通用规范
|
||
|
||
- 影视感图优先 2.39:1（宽银幕）或 16:9
|
||
- 加 `cinematic still / film still / movie scene` 关键词稳定风格
|
||
- 想要胶片质感加 `35mm film grain, color graded`
|
||
- 不写"真实电影名 + 同款风格"（容易被模型拒绝），改用风格描述词
|
||
- **子 agent 是无状态的——每次调用 prompt 都要重复完整的角色外貌描述**（脸型 / 发色 / 发型 / 肤色 / 服装），别指望它"记得"上一张图里这个角色长什么样。跨镜一致的更系统化做法是 Subject Identity Lock 模式：把一份固定的角色描述卡片**逐字粘贴**到每张镜头的 prompt 里，再附同一张参考图。
|
||
- **媒介风格锁**（写实 / 动漫 / 3D）必须显式写在 prompt 里，避免模型在镜头语言关键词的牵引下飘到错误的媒介——具体写法见 `visual-styles.md` 的"媒介风格锁"节。
|
||
|
||
## 配套 skill / reference
|
||
|
||
- **影视视觉风格 + 媒介锁** → `visual-styles.md`（赛博朋克 / 港片夜雨 / IMAX 史诗 等 8 种风格关键词组 + 写实/动漫/3D 媒介锁）
|
||
- **角度定义 / 网格规范 / 姿势库** → `character-sheet-formats.md`
