Jianying Video Gen

使用剪映(Jianying/小云雀)的 Seedance 2.0 模型自动生成AI视频。支持文生视频(T2V)、图生视频(I2V)和参考视频生成(V2V)三种模式。当用户需要生成AI视频、使用Seedance模型创作短片、或基于参考图像/视频进行风格转换时使用此技能。需要预先配置 cookies.json 登录凭证。

Security Scan

The skill largely does what its description says (automates the Jianying web UI via Playwright and requires cookies.json), but it includes baked-in login cookies and several odd hard-coded paths/behavior that are disproportionate and worth caution.

Purpose & Capability

The name/description match the code: the scripts automate xyq.jianying.com using Playwright and require a cookies.json credential file. However, the package already contains a cookies.json with what look like real session cookies (credentials included in the repo), and multiple files hard-code a Windows path (D:\SQLMessage\AI_Videos) as a default output — those choices are not necessary for the stated purpose and are unexpected.

Instruction Scope

SKILL.md instructs the agent to automate the Jianying site, inject cookies, upload reference files, and download generated MP4s. The code follows those instructions (navigates the site, injects cookies, uploads local images/videos, fills forms, polls a task page, and downloads the MP4). It does not appear to read unrelated system files or access external endpoints beyond xyq.jianying.com. Note: by design it will upload any reference files you point it at to the remote service.

Install Mechanism

No install spec is provided (instruction+scripts only). requirements.txt lists Playwright and requests, which is consistent with the code. There is no suspicious remote download/install mechanism in the package itself.

Credentials

The skill does not request environment variables, but the repository ships a cookies.json containing session cookie values for xyq.jianying.com. Bundling credentials with the skill is disproportionate and risky: these cookies grant access to an account on the target service. Also, hard-coded default output paths (D:\SQLMessage\AI_Videos) are unusual and may cause unexpected file creation on installation/runs.

Persistence & Privilege

The skill is not marked always:true and does not request elevated platform privileges. It runs subprocesses to invoke local scripts and creates output directories, which is expected. There is no indication it modifies other skills or system-wide agent settings.

What to consider before installing

This skill automates the Jianying web UI and requires valid cookies.json credentials to work. Before installing: 1) Do NOT trust the included cookies.json — it contains session cookies packaged with the skill; treat that as a credential leak. Replace it with your own exported cookies if you intend to use the skill, or remove the file and provide your own. 2) Expect the skill to upload any reference image/video you point it at to the Jianying service (that is its purpose). 3) Note the odd hard-coded Windows output path (D:\SQLMessage\AI_Videos) in multiple scripts — change output paths to a safe, intended location before running. 4) Run in an isolated environment (sandbox/VM) the first time to observe behavior, and do not reuse sensitive account credentials included in the package. If you need higher assurance, ask the author for a public homepage or source repo and a version that does not include baked-in credentials.

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

1. Python 3.9+ + playwright 已安装
2. Chromium 已通过 playwright install chromium 安装
3. 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"

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。

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。
