Video Summary Skill
Intelligent video summarization for multi-platform content. Supports Bilibili, Xiaohongshu, Douyin, YouTube, and local video files.
What It Does
- - Auto-detect platform from URL (Bilibili/Xiaohongshu/Douyin/YouTube)
- Extract subtitles/transcripts using platform-specific methods
- Generate structured summaries with key insights, timestamps, and actionable takeaways
- Multi-format output (plain text, JSON, Markdown)
- Direct LLM integration — outputs ready-to-use summaries
- Automatic cleanup — no temp file leaks
Quick Setup
No API key required to run. This skill extracts video content and outputs structured requests for summarization. The agent (or external tool) handles LLM calls.
CODEBLOCK0
How it works:
- 1. Script extracts video subtitles/transcript
- Script outputs a structured summary request (JSON/text)
- Agent or external tool calls LLM API with the request
- Script does NOT directly call any external APIs
Supported LLM Providers
- - OpenAI: https://platform.openai.com/api-keys
- Zhipu GLM: https://open.bigmodel.cn/
- DeepSeek: https://platform.deepseek.com/
- Moonshot: https://platform.moonshot.cn/
Just set OPENAIBASEURL to the provider's API endpoint.
Cookie Configuration (Optional)
Xiaohongshu and Douyin may need cookies for some videos:
CODEBLOCK1
⚠️ Cookie Security Note:
- - Cookie files contain session tokens and are sensitive
- Only use cookies from your own browser sessions
- Do not share cookie files with others
- Cookie files are read locally and never transmitted externally by this script
Manual Trigger
If configuration is incomplete, say:
"help me configure video-summary"
Quick Start

CODEBLOCK2
Basic Usage
CODEBLOCK3
In OpenClaw Agent
Just say:
"Summarize this video: [URL]"
The agent will automatically:
- 1. Detect the platform
- Extract video content
- Generate a structured summary
Commands Reference
| Command | Description |
|---|
| INLINECODE0 | Generate standard summary |
| INLINECODE1 |
Chapter-by-chapter breakdown |
|
video-summary "<url>" --subtitle | Extract raw transcript only |
|
video-summary "<url>" --json | Structured JSON output |
|
video-summary "<url>" --lang <code> | Specify subtitle language (default: auto) |
|
video-summary "<url>" --output <path> | Save output to file |
|
video-summary "<url>" --cookies <file> | Use cookies file |
|
video-summary "<url>" --transcribe | Force Whisper transcription |
How It Works
Platform Support Matrix
| Platform | Subtitle Extraction | Notes |
|---|
| YouTube | Native CC + auto-generated | Best support |
| Bilibili |
Native CC + backup methods | Requires video ID extraction |
|
Xiaohongshu | Limited (OCR fallback) | No native subtitles, uses transcription |
|
Douyin | Limited (OCR fallback) | Short-form video, may need transcription |
|
Local files | Whisper transcription | Supports mp4, mkv, webm, mp3, etc. |
Supported URL Formats
YouTube:
Bilibili:
- - INLINECODE10
- INLINECODE11
Xiaohongshu:
- - INLINECODE12
- INLINECODE13 (short link)

Performance Estimation
Whisper Transcription Time
| Video Duration | tiny | base | small | medium |
|---|
| 5 min | ~30s | ~1m | ~2m | ~4m |
| 15 min |
~1.5m | ~3m | ~6m | ~12m |
| 30 min | ~3m | ~6m | ~15m | ~30m |
| 60 min | ~6m | ~12m | ~30m | ~60m |
Notes:
- - GPU significantly faster (3-10x)
- INLINECODE16 model recommended for balance
- First run downloads model (~150MB for base)
Subtitle Extraction Time
| Platform | Time | Notes |
|---|
| YouTube | ~5s | Direct subtitle download |
| Bilibili |
~5s | Direct subtitle download |
| Xiaohongshu | ~3m | Requires transcription |
| Douyin | ~2m | Requires transcription |
Advanced Configuration
Whisper for Transcription
For platforms without native subtitles (Xiaohongshu, Douyin), install Whisper:
CODEBLOCK5
Then configure:
CODEBLOCK6
OpenAI API for Summarization
This script does NOT directly call LLM APIs. It outputs structured requests for the agent to process.
If you want the agent to call LLM for summarization, configure:
CODEBLOCK7
Without API key: Script outputs transcript and structured request. Agent handles summarization.
Cookie Configuration for Restricted Content
Some platforms require authentication for certain content:
CODEBLOCK8
How to get cookies:
- 1. Install browser extension: "Get cookies.txt LOCALLY"
- Login to the platform
- Export cookies to file
Custom Summary Prompt
Create ~/.video-summary/prompt.txt:

Troubleshooting
"No subtitles found"
- - The video may not have subtitles/CC
- Try
--transcribe to use Whisper - For Xiaohongshu/Douyin, transcription is required
"yt-dlp: command not found"
CODEBLOCK13
"Missing required dependencies"
CODEBLOCK14
"Video too long"
Long videos (>1h) are automatically chunked:
- - Split into 10-minute segments
- Summarize each segment
- Merge into final summary
"Failed to fetch video info"
- - Video may be private or deleted
- Try
--cookies for restricted content - Region-locked videos may not work
"Rate limited"
- - Too many requests to platform
- Wait a few minutes
- Use
--cookies for authenticated access

Whisper转录
对于无原生字幕的平台（小红书、抖音），安装Whisper：
bash
pip install openai-whisper
然后配置：
bash
export VIDEOSUMMARYWHISPER_MODEL=base # tiny, base, small, medium, large
OpenAI API摘要
此脚本不直接调用LLM API。 它输出结构化请求供智能体处理。
如果您希望智能体调用LLM进行摘要，请配置：
bash
可选：LLM提供商的API密钥
export OPENAIAPIKEY=your-api-key-here
可选：自定义API端点（用于非OpenAI提供商）
export OPENAIBASEURL=https://open.bigmodel.cn/api/paas/v4 # 智谱
export OPENAIBASEURL=https://api.deepseek.com/v1 # DeepSeek
export OPENAIBASEURL=https://api.moonshot.cn/v1 # 月之暗面
可选：模型选择
export OPENAI_MODEL=gpt-4o-mini
无API密钥： 脚本输出转录文本和结构化请求。智能体处理摘要。
受限内容的Cookie配置
某些平台需要身份验证才能访问特定内容：
bash
方法1：命令行
video-summary https://www.xiaohongshu.com/explore/xxxxx --cookies cookies.txt
方法2：环境变量
export VIDEOSUMMARYCOOKIES=/path/to/cookies.txt
如何获取Cookie：
- 1. 安装浏览器扩展：Get cookies.txt LOCALLY
- 登录平台
- 将Cookie导出到文件
自定义摘要提示
创建 ~/.video-summary/prompt.txt：
markdown
