Seedance + waoowaoo Video Pipeline

Overview

Use this skill for story-to-short-video work where:

Seedance handles pre-production thinking

waoowaoo handles production state and media execution

delivery must distinguish raw / subtitled / voiced / final / merged outputs

Seedance upstream must support its own independent configuration for:

厂商

接口地址

模型名

API Key

This upstream configuration must remain decoupled from downstream image / video / TTS / ambience settings.

This skill is not tied to one video vendor. Model/provider choice stays configurable. Do not force Vidu unless the user explicitly asks for it.

When to use

Typical triggers:

“把小说做成短视频”

“先出分镜，再出片”

“统一风格做连续短视频”

“先保一条完整可交付视频”

“做 6 秒短视频流水线”

“先做一条，再继续拼接后面的”

Trigger rules

Auto-trigger

Trigger this skill immediately when:

the user wants to turn a story / novel / bridge scene into short video

the user asks for script → storyboard → video flow

the user asks for a continuous multi-clip narrative short video

the user gives only one topic / one sentence / 一句文案 and expects the agent to start from scratch

Conditional trigger

Use this skill but enter mid-pipeline when the user already has part of the chain ready, such as:

existing script

existing storyboard

existing panel ids / panel images

existing raw clips

existing subtitle / TTS / ambience outputs

In that case, resume from the highest reliable completed stage instead of forcing a full restart.

Do not trigger

Do not use this skill for:

one-off format conversion

long-form manual editing

DAW-heavy sound design

workflows that depend on fragile manual web login

pure technical maintenance that is not story-to-video production

Core principle

先保主条目，再扩张；先保真实状态，再汇报完成。

默认从 0 开始。 If the user gives only one short idea / one sentence / one文案, this skill must start from the Seedance pre-production side:

story intent

script line

story pack

storyboard / panel plan

first image approval

then downstream video generation

Do not jump directly into middle-stage project APIs, image regeneration, or video submission unless the user explicitly says they already have script/storyboard/panels ready.

Treat the pipeline as 7 execution phases instead of abstract layers:

0. 剧本前置思考 / Story Intent Brief 1. 目标确认 2. 素材确认 3. 视频生成 / 获取 4. 单条完善 5. 多条拼接 6. 交付汇报

Default execution policy

When the user does not specify otherwise:

1. Prefer one fully finished main clip over many half-finished clips 2. Treat database/project state as source of truth 3. Do not count probe tasks as formal deliverables 4. Subtitle text is authoritative unless the user explicitly overrides it 5. Ambience must sound like environment, not generic music bed 6. If quota is tight, finish the current main clip end-to-end before expanding 7. Lipsync is an optional downstream stage, not a default requirement

User modes

Before running, decide which mode the user is asking for.

Mode A — 单条保交付模式

Use when the user wants one clip fully usable before anything else.

Default behavior:

lock one clip as the main target

do not expand to neighbors until this clip is stable

prioritize end-to-end delivery over exploration

Mode B — 逐步确认模式

Use when the user wants to inspect intermediate outputs.

Typical checkpoints:

outline / story pack

image / keyframe

main raw video

audio direction

final single clip

merged cut

Mode C — 配额敏感直跑模式

Use when the user says “直接做 / 不要一步步问 / 额度有限”.

Default behavior:

only stop at high-risk checkpoints

avoid exploratory retries

preserve formal/probe distinction strictly

Read: references/checkpoint-policy.md

Human-in-loop checkpoints (only two)

The pipeline should run internally end-to-end, but it must pause for user decision at only two checkpoints:

1) 四件套确认（剧本阶段） 2) 首图确认（首图阶段）

If user provides modification hints at either checkpoint, do not handcraft edits manually; route hints back into workflow driver via revision approvals.

Exception:

when runtime.pipelineMode=vidu_simple, the flow may run direct video generation from topic without mandatory pre-production checkpoints (unless user explicitly asks for checkpoint mode).

Unified workflow driver approvals

When scheduling with scripts/run-seedance-workflow.cjs, continue actions must map to stage-specific approvals:

seedance-four-pack-confirm

- pass: --approval four-pack-approved - revise: --approval revise-four-pack --revision-note "<用户修改意见>"

first-image-confirm / first-image-internal-generated / first-image-asset-confirm

- pass: --approval first-image-approved - revise: --approval revise-first-image --revision-note "<用户修改意见>"

first-image-asset-blocked (配置补齐后重试首图)

- retry: --approval retry-first-image

If approval value and stage do not match, the driver must stop with explicit error instead of silently continuing.

First-run configuration

On first run, do not force internal words like provider on the user. Use only:

厂商

接口地址

模型名

API Key

Auto-detect runtime.pipelineMode:

minimax_full (full upstream + downstream)

vidu_simple (direct video-first, minimal keys)

seedance_simple (direct video-first, minimal keys)

Use capability-based routing (not hardcoded model names):

text only: route to best text->video provider

image + text: route to best image+text->video provider

text only + user requests first-image preview: route text->image first

Default routing rule (image + text input):

If user already provides a reference image, after four-pack confirmation prefer direct first_frame binding and skip first-image asset generation.

Keep script/storyboard continuity constraints, but bind identity from source image at pixel level.

Runtime overrides:

--video-vendor

--image-vendor

--prompt-mode

--prompt-style "..."

--prompt-camera "..."

--prompt-scenario

--prompt-auto-fallback （默认 true）

--prompt-min-score <0-100>（默认 80）

Prompt engineering overlay (now built-in):

run-seedance-workflow.cjs --action start will generate prompt-pack.result.json

output includes: mode, assets mapping, timecoded beats, structured prompt blocks

workflow result also includes promptQuality（score/level/suggestions）用于快速判断可用性

when score < threshold, workflow can auto-try alternate scenarios and output promptFallback report

implementation script: scripts/build-seedance-prompt-pack.cjs

ASR routing (subtitle alignment):

prefer volc_asr_auc (X-Api-Key + volc.seedasr.auc)

fallback volc_vc (appid + token, resource vc.async.default)

fallback local faster-whisper

When user explicitly requests “按剧本锁定/严格按剧本”: prefer Seedance strict-script profile

content: text + image_url(first_frame)

explicit duration / resolution / generate_audio / camera_fixed / draft / seed / return_last_frame

do not mix first_frame/last_frame with reference_image in one request body

Adapter note (current release):

direct video submit/poll/download adapters are built-in for minimax / vidu / seedance

config can be single-block (downstream.waoo.video/image) or multi-map (downstream.waoo.videos.*, downstream.waoo.images.*)

If configuration is incomplete, run-seedance-workflow.cjs --action start must return a structured configuration-guidance result instead of throwing or silently continuing.

Hard rule for formal Seedance execution:

Phase 0 / E01_前置思考.md / E01_剧本.md count as formal Seedance outputs only when upstream.seedance is independently configured with a real 厂商 / 接口地址 / 模型名 / API Key.

Do not silently substitute the current chat model as the formal Seedance upstream model.

If upstream.seedance is missing, placeholder-only, or uses demo credentials, explicitly say that formal Seedance pre-production is not yet runnable and switch to configuration guidance mode.

Read:

references/first-run-guidance.md

references/configuration-template.md

Phase 0 — 剧本前置思考 / Story Intent Brief

When the user starts from only a topic /一句文案, do not jump directly into script body or production calls. First build a compact Story Intent Brief that locks:

what exact event this episode is covering

where Episode 1 begins and ends

core conflict

primary viewpoint

intended style / tone

rhythm shape (铺垫 / 设局 / 爆发 / 反转)

whether the idea is better as one clip, one episode, or multi-clip chain

obvious production risks

This brief is part of the formal Seedance pre-production stage, not an optional private thought. It should be reflected forward into E01_剧本.md, E01_素材清单.md, and E01_分镜.md.

User confirmation rule:

After formal Seedance generates the four-pack (E01_前置思考.md, E01_剧本.md, E01_素材清单.md, E01_分镜.md), surface that pack to the user for confirmation.

Do not continue into first-image generation, panel execution, or downstream video generation until the user confirms the four-pack.

Treat this as a required checkpoint, not an optional courtesy.

After the four-pack is confirmed, the skill may continue internally to generate the first-image candidate.

Do not surface the first-image prompt/spec bundle to the user by default.

Instead, surface the actual generated first-image asset to the user, and require that approval before any downstream video generation.

The user only confirms or requests changes.

The assistant's job is only to notify the skill to continue after confirmation.

The next internal workflow steps must still be executed by the skill's own continuation entrypoints, not improvised manually by the assistant.

Phase 0.5 — Prompt Engineering Overlay（已并入）

Before first-image or video submit, apply Seedance prompt-engineering guardrails:

1) Declare mode first: Text-only / First-Frame / First+Last / All-Reference. 2) Add explicit Assets Mapping (@image1/@video1/@audio1 each controls what). 3) Use timecoded beats (one major action per segment). 4) Keep prompt concise and controllable; add Negative Constraints when needed. 5) For strict-script requests, prioritize identity continuity + camera continuity.

If user asks for style-rich cinematic prompts, generate from the prompt playbook and then map into panel execution context (instead of freeform rewriting every time).

Read:

references/seedance-prompt-engineering.md

Phase 1 — 目标确认

Before generating anything, lock the exact target:

episode id

panel id / panelIndex

main clip vs neighbor clip

whether the user wants single clip or merged output

whether the user wants plain mix or optional lipsync

If the target is ambiguous, resolve it first. Do not generate against a guessed panel.

Phase 2 — 素材确认

Resolve the active inputs:

source image / first-frame image

active subtitle text (srtSegment or equivalent)

current video prompt

existing raw outputs

existing TTS / ambience / merged versions

If multiple versions exist, choose the current main clip explicitly.

Before a new generation or first-image approval, run a guard pass for:

panel identity lock

image/text/panel consistency

ordering / duplicate check when multiple panels are involved

Read:

references/waoo-input-spec.md

references/clip-state-contract.md

references/panel-order-guard.md

Phase 3 — 视频生成 / 获取

If the clip does not exist yet: 1. prepare valid input media 2. submit video task 3. poll status 4. retrieve file / real media URL 5. download the actual file 6. classify the result

Possible classifications:

probe only

formal success

duplicate of existing clip

failed

If the clip already exists, do not regenerate unless the user asks.

Read:

references/model-routing.md

references/runtime-policy.md

references/output-contract.md

references/failure-fallbacks.md

Phase 4 — 单条完善

For a single clip, finish in this order: 1. subtitle alignment 2. TTS / dialogue decision 3. ambience decision 4. optional lipsync 5. final single-clip export

Subtitle rule

The active subtitle text wins unless the user explicitly changes it. Do not borrow text from neighboring panels.

Audio rule

Audio strategy must match the user’s request:

旁白为主

环境音优先

不要明显配乐

只要无台词环境版

要真实说话感 / 要口型验证

Read:

references/audio-policy.md

Lipsync rule

Lipsync is optional and should only be used when clearly requested. Do not assume lipsync belongs in the main path.

If lipsync is used:

keep the original full clip as the base truth

treat lipsync output as a candidate until duration / sync / naturalness are checked

never silently replace the formal main clip with an obviously shortened or degraded result

Read:

references/lipsync-decision-tree.md

Phase 5 — 多条拼接

Only merge clips after each included clip has an honest state label.

Before merging:

confirm ordering

confirm each clip’s delivery state

confirm whether to use raw / voiced / ambience / lipsync version

rebalance cross-clip ambience and loudness

Merged output should not be reported as “完整成片” if one included clip is still experimental.

Read:

references/rhythm-rules.md

references/audio-policy.md

Phase 6 — 交付汇报

Always distinguish:

raw generated clip

subtitled clip

subtitle + TTS clip

final single clip

merged clip

Never call a clip “final” if:

narration and subtitle are misaligned

ambience is claimed but not actually audible

the file was accidentally truncated

the result only came from a probe task

Result reporting policy

Always report in this structure:

结论

关键点 (1–2 items)

下一步

Never blur these categories:

probe success

formal success

duplicate output

temporary preview

final delivery

Guardrails

Do not expand from one clip to many unless the current main clip is stable or the user explicitly asks

Do not count probes as formal deliverables

Do not report “统一风格完成” unless the compared clips were intentionally validated as consistent

Do not claim environment sound exists unless it is clearly audible and semantically correct

Do not use a different panel’s text for the active clip narration

Do not hide failures behind “looks okay”

Success definition

A clip is fully delivered only if all are true: 1. the target clip/panel is correctly identified 2. the video file is formally generated or formally accepted 3. subtitles match the clip content 4. narration/dialogue policy matches the user’s request 5. ambience is correct for the scene and audible 6. final mp4 is exportable and sendable 7. delivery status is reported truthfully

If any item is missing, report the clip as partial, not complete.
