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。
