seedance

seedance is a skill for Claude Code, Codex from freestylefly/wesight. It costs 52 tokens per session (4,422 once invoked), scanned A, a copy of seedance, MIT.

A video-generation tool that uses Volcengine’s Seedance AI model to create videos from text or images, including videos whose timing follows audio.

In plain words
What is it for?
Use it for text-to-video, image-to-video, and audio-synced video creation through the Seedance service.
Why use it?
It removes the need to produce every video frame manually and provides an asynchronous process for submitting a generation task, checking its status, and downloading the result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seedance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/generate_video.js, scripts/generate-video.ps1, scripts/generate-video.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

97% identical to seedance — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Seedance 视频生成

使用火山引擎 Seedance 模型生成高质量 AI 视频,支持文本生成视频(T2V)、图片生成视频(I2V)、音画同步等多种创作模式。

Node.js 版本:此脚本使用 Node.js 实现,无需 Python 环境。通过入口脚本自动检测 Node.js 运行时(优先使用系统 node,回退到 WeSight 内置运行时),Windows 和 Mac 用户都可以开箱即用。

配置

  • Base URL: https://ark.cn-beijing.volces.com/api/v3
  • API Key: 从环境变量 ARK_API_KEY 读取
  • 认证方式: Authorization: Bearer {API_KEY}
  • SDK: 兼容火山方舟 Python SDK

如何配置 API Key

方式一:通过环境变量配置(推荐)

在终端中设置环境变量:

# macOS/Linux
export ARK_API_KEY="你的API密钥"

# 或者添加到 ~/.zshrc 或 ~/.bashrc 以永久生效
echo 'export ARK_API_KEY="你的API密钥"' >> ~/.zshrc
source ~/.zshrc
# Windows PowerShell
$env:ARK_API_KEY="你的API密钥"

# 或者设置系统环境变量以永久生效
[System.Environment]::SetEnvironmentVariable('ARK_API_KEY', '你的API密钥', 'User')

方式二:通过 WeSight 启动时注入

WeSight 会自动读取系统环境变量,确保在启动 WeSight 前已设置 ARK_API_KEY

如何获取 API Key:

  1. 访问火山方舟控制台:https://console.volcengine.com/ark/region:ark+cn-beijing/apikey
  2. 创建新的 API Key
  3. 复制密钥并设置为环境变量

前置检查

无需安装任何依赖! 该脚本已兼容 Node.js 内置模块。

WeSight 已包含 Node.js 运行时,所有必要的依赖已被自动打包。Windows 和 Mac 用户无需额外配置。

工作流程

Seedance 视频生成是一个异步过程:

  1. 提交任务 - 调用 API 创建视频生成任务,获得 task_id
  2. 轮询状态 - 每隔几秒查询任务状态,直到状态变为 succeeded
  3. 下载视频 - 从 video_url 字段下载生成的 MP4 文件

配额和限制

免费额度

所有 Seedance 模型在 **default 模式(在线推理)**下提供:

  • 200万 token 免费额度
  • flex 模式(离线推理)无免费额度

注意:文档中未明确说明 200万 token 能生成多少个视频,消耗取决于视频时长、分辨率和是否使用图片/音频。建议先小批量测试。

限流限制

模型系列 RPM(每分钟请求数) 并发数 TPD(离线模式每日token)
Pro 系列 600 10 5000亿
Lite 系列 300 5 2500亿
  • RPM 限流:账号下同模型每分钟允许创建的任务数量上限
  • 并发数限制:同一时刻在处理中的任务数量上限
  • TPD 限流:flex 模式下一天内对同一模型的总调用 token 上限

视频保存时间

⚠️ 重要提醒

  • 任务数据(包括视频URL)仅保留 24 小时
  • 超时后会被自动清除
  • 务必及时下载保存生成的视频

使用示例

路径说明:下面的示例使用 $SKILLS_ROOT 环境变量来引用脚本路径。WeSight 会自动设置这个变量,指向实际的 SKILLs 目录位置,因此无需手动修改路径。

1. 文本生成视频(T2V)

根据文字描述生成视频,适合创意激发和概念验证。

bash "$SKILLS_ROOT/seedance/scripts/generate-video.sh" \
  --prompt "一只小猫在草地上玩耍,阳光明媚,镜头缓缓推进" \
  --duration 5 \
  --output generated_video.mp4

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
