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
- 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)
- 转场必须匹配 Visual Medium — VHS 视频不能用 film burn,16mm 不能用 digital glitch
- 转场是瞬间事件(0.5-1s),不是持续效果 — 用
briefly,for a split second,momentarily - 转场之后必须描述恢复 —
then snaps back,then stabilizes,then returns - 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?
