name: seedance-story-orchestrator description: Orchestrate script-to-final-video production with a strict stage-gated workflow (outline → episode_plan → storyboard → storyboard_images → render), using Seedream image generation, Seedance multi-shot rendering, checkpoint-based confirmation/resume, and optional FFmpeg concatenation. Use when converting txt/json/staged artifacts into storyboard videos and a final merged mp4.

Seedance Story Orchestrator (v0.2.0-phase1)

阶段性方案（Phase 1）：

• 上层编排：seedance-story-orchestrator

• 下层执行：seedance-video-generation/seedance.py

以“可审计、可恢复、可控推进”为第一目标。

Workflow（严格关卡）

固定阶段顺序： outline -> episode_plan -> storyboard -> storyboard_images -> render 规则：

• 每阶段执行后写入 checkpoint-{stage}.json，默认 confirmed=false

• 未确认时，run 会立即停止并返回：

• pending_confirmation_stage

• next_action

• 必须 confirm --stage 后再继续下一阶段

Prerequisites

• Python 3.8+

• seedance-video-generation skill（必须可访问 seedance.py）

• ARK_API_KEY

• FFmpeg（用于拼接最终视频）

Quick Start（推荐）

``bash

1) 运行到 render（会在每个关卡停下）

python3 {baseDir}/scripts/run_story.py run \ --project-dir {baseDir}/outputs/my-project \ --input-file /path/to/story.txt \ --stage render

2) 按提示确认阶段（示例）

python3 {baseDir}/scripts/run_story.py confirm \ --project-dir {baseDir}/outputs/my-project \ --stage outline

3) 查看整体状态

python3 {baseDir}/scripts/run_story.py status \ --project-dir {baseDir}/outputs/my-project `

End-to-End（从剧本到成片）

`bash

首次运行（会停在 outline）

python3 {baseDir}/scripts/run_story.py run \ --project-dir ./my-project \ --input-file ./story.txt \ --stage render

逐关确认并继续

python3 {baseDir}/scripts/run_story.py confirm --project-dir ./my-project --stage outline python3 {baseDir}/scripts/run_story.py run --project-dir ./my-project --stage render python3 {baseDir}/scripts/run_story.py confirm --project-dir ./my-project --stage episode_plan python3 {baseDir}/scripts/run_story.py run --project-dir ./my-project --stage render python3 {baseDir}/scripts/run_story.py confirm --project-dir ./my-project --stage storyboard python3 {baseDir}/scripts/run_story.py run --project-dir ./my-project --stage render python3 {baseDir}/scripts/run_story.py confirm --project-dir ./my-project --stage storyboard_images python3 {baseDir}/scripts/run_story.py run --project-dir ./my-project --stage render python3 {baseDir}/scripts/run_story.py confirm --project-dir ./my-project --stage render ` 最终视频路径： ./my-project/videos/run-YYYYMMDD-HHMMSS/final-video.mp4

Input Modes

1) 非结构化输入（默认推荐：sub-agent-first）

`bash

先生成 sub-agent 任务

python3 {baseDir}/scripts/build_subagent_task.py \ --input-file /path/to/raw.txt \ --output {baseDir}/outputs/subagent-task.txt

用 sessions_spawn 执行后，拿到结构化 JSON，再喂给 prepare

python3 {baseDir}/scripts/prepare_storyboard.py \ --input-file /path/to/subagent-output.json \ --output-dir {baseDir}/outputs `

2) 直接文本/JSON输入

`bash python3 {baseDir}/scripts/prepare_storyboard.py \ --input-file /path/to/story.txt \ --output-dir {baseDir}/outputs `

3) staged artifacts 输入

`bash python3 {baseDir}/scripts/prepare_storyboard.py \ --staged-artifacts /path/to/staged-artifacts.v1.json \ --output-dir {baseDir}/outputs `

Core Commands

Prepare

`bash python3 {baseDir}/scripts/prepare_storyboard.py \ --input-file /path/to/story.txt \ --output-dir {baseDir}/outputs `

Storyboard Images（Seedream）

`bash python3 {baseDir}/scripts/seedream_image.py storyboard \ --storyboard /path/to/storyboard.draft.v1.json \ --output-dir {baseDir}/outputs/images `

Render Videos（Seedance）

`bash python3 {baseDir}/scripts/orchestrate_story.py run \ --storyboard /path/to/storyboard.draft.v1.json \ --output-dir {baseDir}/outputs/videos `

Concat Final Video

`bash python3 {baseDir}/scripts/concat_videos.py \ --run-dir {baseDir}/outputs/videos/run-YYYYMMDD-HHMMSS `

Artifacts

主要产物：

• plan-*/storyboard.draft.v1.json

• plan-*/assets.v1.json

• plan-*/staged-artifacts.v1.json

• checkpoint-{stage}.json

• videos/run-*/result-index.json

• videos/run-*/run-summary.json

• videos/run-*/final-video.mp4

Notes (Phase 1)

• 当前是阶段性方案：优先可控、可恢复、可审计

• 自动“回传最终视频到会话”不在本阶段强制实现（可在 Phase 2 增加）

• run_story.py` 已内置混合日志 JSON 解析与严格关卡机制
