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)?
  • 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?
