Seedance Storyboard Generator

If the user asks for only one narrow task, such as a single storyboard prompt, a continuation prompt, a video edit prompt, or only an asset list, skip unrelated steps and do only that part.

Guided Workflow

1. Intake And Configuration

Treat this as the default first step when the user says something like seedance 风云中聂风小时候的故事 or provides only a rough topic.

Determine input type:

• full text: complete novel, article, or story requiring adaptation and episode segmentation
• outline: brief concept or one-sentence premise requiring full script development

Extract core elements, then collect or infer:

• source material or one-sentence story premise
• protagonist(s) and key characters
• central conflict and narrative arc
• setting or world-building elements
• key plot points and emotional beats
• visual style
• aspect ratio
• target duration or episode count
• tone
• whether the user already has images, videos, or audio references

If the input is ambiguous or incomplete, ask clarifying questions only where the missing detail would materially change the result.

Confirm production parameters explicitly:

1. visual style: 写实 / 动画 / 水墨 / 科幻 / 复古 / 电影感 / 其他
2. duration: total runtime or per-episode duration and episode count
3. target platform: aspect ratio such as 16:9 / 9:16 / 2.35:1
4. tone: overall emotional tone such as 史诗 / 温馨 / 悬疑 / 欢快 / 忧伤

Document these parameters once and apply them consistently across the script, asset prompts, and storyboard files.

Ask only for missing parameters that materially change the result. If reasonable defaults are obvious, state them once and continue instead of blocking.

Recommended defaults when the user gives only a theme:

• language: Chinese
• aspect ratio: 9:16
• duration: 15s per episode
• structure: multi-episode short drama
• deliverables: script + asset list + storyboard package + chaining notes

2. Script Development

Convert the source material into a four-act script structure aligned with the repo workflow:

• 起: episodes 1-5
• 承: episodes 6-10
• 转: episodes 11-15
• 合: episodes 16-20

For shorter series, preserve the same escalation pattern in fewer episodes.

For each episode include:

• episode number and title
• duration
• emotional tone
• key plot points
• beginning frame
• ending frame

If the source is still loose or literary, use references/故事转视频脚本-转换工具.md to first extract theme, conflict, character arc, scenes, and dramatic beats.

3. Asset Planning

Create reusable asset prompts before storyboard writing. This is the Nana Banana Pro prompt stage in the upstream workflow.

Use the numbering scheme:

At the top of the asset list, declare one shared style prefix for the whole project:

## 统一风格前缀

[Style prefix]

Then use the upstream prompt format for every reusable asset:

### [编号] — [名称]

[detailed visual description in English], [technical specs]

Style prefix examples:

• Chinese ink wash painting style mixed with anime cel-shading
• Cinematic photorealistic style with dramatic lighting
• 3D Pixar-style animation rendering
• Sci-fi cyberpunk aesthetic with neon lighting

Requirements:

• use one shared style prefix across the whole project
• show the shared style prefix once at the beginning of [标题]_素材清单.md, not inside every asset prompt
• make each prompt directly usable in Nana Banana Pro or another image model
• for character assets, explicitly name the character in each prompt (do not use generic labels like "a young warrior" without the character name)
• when available, include both Chinese name and official English name in character prompts
• preserve recurring identity markers for characters
• use distinct color schemes and visual markers for each character to ensure recognition
• keep the list organized with unique IDs suitable for copy-pasting into image generators

4. Image Generation Handoff

The skill does not generate images itself. After producing the asset list, explicitly instruct the user to generate the referenced images with Nana Banana Pro or another image model before video production.

Mention the practical handoff:

• open [标题]_素材清单.md
• generate the listed character, scene, and prop images
• keep filenames or IDs stable so they can be mapped back into storyboard slots

5. Storyboard Script Generation

After the script and asset plan are ready, generate Seedance 2.0 storyboard files in the repo's production format.

Each episode storyboard should contain:

1. 素材上传清单
2. Seedance Prompt
3. 尾帧描述

Use the upstream structure:

图片1: C01 (角色参考)
图片2: S03 (场景参考)
图片3: P01 (道具参考)

Then write the Seedance prompt in time-axis format:

[风格描述]，[画幅比例]，[整体氛围]

0-3s画面：[镜头运动]，[场景建立]，[主体引入]
3-6s画面：[镜头运动]，[情节发展]，[动作描述]
6-9s画面：[镜头运动]，[高潮/冲突]，[情绪爆发]
9-12s画面：[镜头运动]，[转折/过渡]
12-15s画面：[镜头运动]，[结尾/落版]

【声音】[配乐风格] + [音效] + [对白/旁白]
【参考】@图片1 [用途]，@图片2 [用途]，@视频1 [用途]，@音频1 [用途]

And finish with a plain-language ending frame description for next-episode continuity.

Use camera movement keywords consistent with the upstream skill:

• 推镜头
• 拉镜头
• 摇镜头
• 移镜头
• 跟镜头
• 环绕镜头
• 升降镜头
• 希区柯克变焦
• 一镜到底
• 手持晃动

6. Episode Chaining

Explain the chain-generation workflow exactly as a production note:

• E01 is generated as a new video
• E02 extends E01 by uploading E01 as @视频1
• E03 extends E02
• continue the same pattern for later episodes

When continuity matters, start the prompt with:

将@视频1延长X秒

Then describe only the newly added segment and any transition needed from the previous ending frame.

If the user specifically wants strict upstream behavior for chaining, default to 将@视频1延长15s for standard 15-second episodes.

Narrow Task Modes

If the user requests a specific subtask, switch to the corresponding mode instead of forcing the full drama workflow:

• single storyboard or short prompt
• asset prompt generation only
• Seedance video extension
• Seedance video edit or rewrite
• product, travel, battle, voice, or template-driven prompts from the manual

Use references/seedance-manual.md for the correct template in these narrow modes.

Output Files

When the user wants the default post workflow, a repo-aligned project, or production-ready files, create separate Markdown files in the workspace by default. Do not collapse a multi-episode project into one combined storyboard file unless the user explicitly asks for a single-file delivery.

Use these names:

1. [标题]_剧本.md
2. [标题]_素材清单.md
3. [标题]_E[XX]_分镜.md

For a 5-episode project, that means:

• one [标题]_剧本.md
• one [标题]_素材清单.md
• five storyboard files: [标题]_E01_分镜.md through [标题]_E05_分镜.md

Only use a single combined Markdown file when the user explicitly asks for inline output, a draft preview, or one-file delivery.

Interaction Rules

• Prefer Chinese output when the user or source material is Chinese.
• If the user provides only a theme, guide them through setup briefly and continue with reasonable defaults.
• If any character identity, source, or canonical setting is unclear, search the web first, summarize the likely matches with sources, and ask the user to confirm before continuing script, asset, or storyboard generation.
• If a character cannot be found through reliable sources, or the search results are too ambiguous to identify the intended character confidently, stop and ask the user which character they mean. Do not substitute a guessed match or continue with an invented identity.
• For character names, run a separate web search for the official English name (not only Chinese aliases or transliterations); do not invent or infer an English name without a source. If no reliable source is found, mark it as unknown and ask the user to confirm.
• In Nana Banana character prompts, always call out the character by name explicitly; do not replace named characters with vague role words.
• Keep IDs stable once assigned.
• Make references explicit whenever using @图片X, @视频X, or @音频X.
• Use explicit names instead of ambiguous pronouns when continuity matters.
• Keep prompts practical and production-ready rather than literary.

Quality Assurance

Before finalizing:

• verify every @图片X, @视频X, and @音频X reference has a corresponding upload slot
• check episode-to-episode continuity from ending frame to next opening frame
• ensure the time axis covers the full requested duration
• validate camera movements are feasible and logically sequenced
• ensure all recurring characters, scenes, props, wardrobe, and injuries remain consistent
• ensure the asset list declares one shared style prefix at the top and does not repeat it inside every reusable asset prompt
• ensure every Nana Banana character prompt explicitly includes the character name (and official English name when available)
• ensure the Nana Banana asset prompts and Seedance prompt blocks can be copied into the production workflow with minimal cleanup

Common Pitfalls To Avoid

1. Do not force a full multi-episode workflow when the user only wants one prompt.
2. Do not ask unnecessary setup questions when safe defaults are obvious.
3. Do not generate asset IDs that are later changed or renumbered.
4. Do not ignore Seedance reference limits or continuation mechanics.
5. Do not output only literary summaries when the user needs executable production prompts.
