# Story Prompt Guide — 故事剧本 Prompt 编写规则 Seedance 的 prompt 是一个**完整的故事短片剧本**,不是分镜的拼接。模型需要理解「发生了什么事」才能生成连贯的视频。 --- ## Prompt 结构 ``` [Opening] image 1 is a 9-panel storyboard showing the complete story progression. The video begins with the top-left panel: [完整的开场场景描述,纯环境,产品未出现,光线如何,3-4句]. [Transition — 1st] [匹配 Visual Medium 的转场特效,如 "A brief white flash fills the frame, then clears —"] [Inciting event] [故事的触发点——什么开始变化,从画面的哪个位置开始,2-3句]. [变化的初始阶段——速度慢,范围小,具体描述物理形态]. [Rising action] [变化加速和扩展——从哪里蔓延到哪里,覆盖了什么,新元素出现,2-3句]. The story progresses through the middle panels of the storyboard. [变化到达中间状态的具体描述]. [Transition — 2nd] [第二个转场特效(可选),如 "The image fragments into pixel blocks for a split second, snaps back —"] [Climax] [变化到达顶峰——最戏剧性的瞬间,画面被变化填满,2-3句]. The scene matches the bottom panels of the storyboard. [Resolution] [最终定格——产品在变化后的世界中居中,品牌信息呈现,1-2句]. Throughout: [产品] remains [不变状态]. No visible human face. [Visual Medium 关键词 + 介质瑕疵]. [camera movement]. ``` --- ## 关键原则 - 这是一个有**起承转合**的故事,不是几张图的说明文字 - `image 1` 是九宫格分镜图,包含完整的视觉叙事弧线。Prompt 引导模型沿分镜图的面板顺序(左→右,上→下)展开故事 - 故事是连续的——句子之间用因果关系和时间推进连接,不是断裂的场景罗列 - 变化必须有**物理细节**:什么物体、从哪里开始、向什么方向、以什么速度、变成什么形态 - 禁止叙事词(realizes, decides, despite)、情感词(feels, thinks, surprised) - 只用**视觉动词**:grows, spreads, cracks, crawls, floats, shatters, freezes, rotates, fills --- ## Transition Effects — 转场特效词库 在故事节拍之间插入 **1-2 个转场特效**,增加视觉冲击力和节奏感。转场必须与 Visual Medium 匹配——VHS 用 analog 类转场,Film 用 organic 类转场,所有介质都可以用 camera 类转场。 ### 转场词库(按介质分类) | 类别 | 转场效果 | Prompt 关键词 | |------|---------|-------------| | **Analog (VHS/Phone)** | 闪白 | `a brief white flash fills the frame` | | | 信号干扰 | `static noise bursts across the screen for a split second` | | | 数码故障 | `digital glitch — the image fragments into pixel blocks, then snaps back` | | | 扫描线爆裂 | `horizontal scan lines tear across the frame` | | | 色差闪烁 | `RGB channels split apart momentarily, chromatic aberration flickers` | | | 跟踪错误 | `VHS tracking error — the image rolls vertically, then stabilizes` | | **Organic (16mm/Super8/35mm)** | 胶片灼烧 | `a film burn blooms from the edge — orange and white light bleeds across the frame` | | | 光泄漏 | `warm light leaks bleed in from the right edge` | | | 曝光闪烁 | `the exposure pulses — the image briefly washes out to overexposed white, then returns` | | | 帧跳 | `a single-frame jump cut — the composition shifts abruptly` | | | 化学晕染 | `color bleeds outward like chemicals spreading on wet paper` | | **Camera (通用)** | 闪光灯 | `a camera flash strobes — freezing the scene in harsh white light for an instant` | | | 快速甩镜 | `a whip pan blurs the frame horizontally, revealing the next scene` | | | 焦点爆炸 | `focus racks violently to full blur, then snaps sharp on [target]` | | | 镜头眩光 | `a lens flare streaks across the frame as light source shifts` | ### 使用规则 1. **每段视频最多 2 个转场**,放在故事节拍转换处(Opening→Inciting / Rising→Climax 最合适) 2. **转场必须匹配 Visual Medium** — VHS 视频不能用 film burn,16mm 不能用 digital glitch 3. **转场是瞬间事件**(0.5-1s),不是持续效果 — 用 `briefly`, `for a split second`, `momentarily` 4. **转场之后必须描述恢复** — `then snaps back`, `then stabilizes`, `then returns` 5. **禁止连续转场** — 两个转场之间至少隔一个故事节拍 ### Prompt 中的写法 转场插入在两个节拍之间,作为一个独立短句: ``` [Opening scene description, 2-3 sentences]. [Transition — e.g. "A brief white flash fills the frame, then clears to reveal:"] [Inciting event — change begins, 2-3 sentences]. [Rising action accelerates, 2-3 sentences]. [Transition — e.g. "The image fragments into pixel blocks for a split second, snaps back —"] [Climax — maximum intensity, 2-3 sentences]. [Resolution — final composition, 1-2 sentences]. ``` --- ## 检查清单 - [ ] 读起来像一个完整的故事(有开头、发展、高潮、结尾)? - [ ] 用 `image 1` 引用了九宫格分镜图? - [ ] 变化有物理细节(起点位置、方向、速度、形态)? - [ ] 句子之间有因果/时间连接,不是断裂的场景列表? - [ ] 产品的不变状态被显式声明? - [ ] 包含 `no visible human face`? - [ ] 包含 Visual Medium 关键词 + 介质瑕疵(与九宫格 prompt 一致)? - [ ] 包含 1-2 个转场特效,且与 Visual Medium 匹配? - [ ] 整段 prompt 在 150-250 词之间? - [ ] 结尾明确描述了最终定格画面?
