Summary
This automates JianYing's Seedance 2.0 model using Playwright to generate AI videos without touching the web UI. You get four modes: text-to-video, image-to-video, video-to-video style transfer, and extending existing clips. It handles the full workflow,logs in with cookies, fills forms, intercepts thread IDs, polls for completion, and downloads the MP4. Runs 3-5 credits per second depending on whether you pick Fast or standard. The dry-run mode is smart, letting you debug form state with screenshots before burning credits. You'll need Python 3.9+, a cookies.json from your browser session, and patience for video uploads (60-90 seconds for 8MB). Good for batching video generation or integrating JianYing into larger pipelines.

剪映 AI 视频生成器
通过 Playwright 自动化操作剪映(xyq.jianying.com)，使用 Seedance 2.0 模型生成 AI 视频。
前置条件
- Python 3.9+ +
playwright已安装 - Chromium 已通过
playwright install chromium安装 - cookies.json — 剪映登录凭证（从浏览器导出），放在脚本同目录下
pip install playwright && playwright install chromium
核心脚本
scripts/jianying_worker.py — 主自动化脚本
使用方式
文生视频 (T2V)
python3 scripts/jianying_worker.py \
--cookies /path/to/cookies.json \
--output-dir /path/to/output \
--prompt "赛博朋克风格的长安城，飞行汽车穿梭在霓虹灯笼之间" \
--duration 10s \
--model "Seedance 2.0"
图生视频 (I2V)
python3 scripts/jianying_worker.py \
--cookies /path/to/cookies.json \
--output-dir /path/to/output \
--ref-image /path/to/image.png \
--prompt "将这张图片变成动画，镜头从左向右缓慢平移" \
--duration 10s \
--model "Seedance 2.0 Fast"
参考视频生成 (V2V)
python3 scripts/jianying_worker.py \
--cookies /path/to/cookies.json \
--output-dir /path/to/output \
--ref-video /path/to/reference.mp4 \
--prompt "画风改成宫崎骏风格，其他不变" \
--duration 10s \
--model "Seedance 2.0"
向后延伸 (Extend)
python3 scripts/jianying_worker.py \
--cookies /path/to/cookies.json \
--output-dir /path/to/output \
--extend-url 'https://xyq.jianying.com/home?tab_name=integrated-agent&thread_id=YOUR_THREAD_ID&agent_name=pippit_video_part_agent' \
--prompt "向后延伸，保持人物和镜头语言一致" \
--duration 5s
Dry-Run 模式（调试用）
python3 scripts/jianying_worker.py --cookies /path/to/cookies.json --prompt "测试" --dry-run
只填写表单不提交，生成
step_*.png截图供检查。 对 V2V 来说，dry-run 现在还会输出一段表单状态JSON，用来确认参考视频缩略图是否已挂上、发送按钮是否已解锁。

--ref-video | 无 | 本地视频路径 | V2V 模式的参考视频 |
--extend-url | 无 | thread 链接 | Extend 模式，基于已有视频继续生成 |
--cookies | cookies.json | 文件路径 | 剪映登录凭证路径 |
--output-dir | . | 目录路径 | 输出视频保存目录 |
--dry-run | false | - | 只填表不提交 |
模型与积分
| 模型 | 积分/秒 | 5s | 10s | 15s | 特点 |
|---|---|---|---|---|---|
| Seedance 2.0 Fast | 3 | 15 | 30 | 45 | 快速，适合测试 |
| Seedance 2.0 | 5 | 25 | 50 | 75 | 高质量，正式出片 |
自动化流程
登录(cookies) → 选模式(沉浸式短片) → 选模型 → [上传参考素材/打开已有 thread 并点向后延伸] → 选时长 → 输入Prompt → 发送
→ 拦截 thread_id → 导航详情页 → 轮询视频 → curl 下载 MP4
提示词编写指南
详细的提示词示例和编写技巧参见 references/prompt-guide.md。
常见问题
Q: cookies 过期了怎么办？ 在浏览器登录 xyq.jianying.com，使用 EditThisCookie 等扩展导出 cookies.json。
Q: 下载 403？ 脚本使用 thread_id 详情页 + curl 下载，CDN 链接无需 cookie。如仍失败检查网络。
Q: 上传参考视频很慢？ 正常，8MB 视频约需 60-90 秒。脚本会自动等待最多 5 分钟。
