📖 About This Skill

name: video-transcript version: 1.0.0 description: Extract transcripts/subtitles from video URLs and deliver as .docx files. Use this skill whenever the user provides a video link (YouTube, Bilibili, or any yt-dlp supported platform) and asks for a transcript, subtitles, lecture notes, or spoken content in text form. Also trigger when user says "帮我把这个视频转成文字", "视频讲稿", "字幕文档", "transcript", "lecture notes from video", or pastes a video URL with any request to get the text content. compatibility: tools: - exec dependencies: - name: yt-dlp install: "pip install yt-dlp # or: winget install yt-dlp" check: "yt-dlp --version" - name: node install: "https://nodejs.org" check: "node --version" - name: docx (npm, local) install: "cd ~/.agents/skills/video-transcript/scripts && npm install" check: "node -e \"require('./node_modules/docx')\""

Video Transcript Skill

Extract subtitles from a video URL and deliver clean .docx transcript files. For non-Chinese videos, produce two files: original language + Chinese translation. For Chinese videos, produce one file.

Workflow

Step 0 — First-time setup (once only)

Check if node_modules exists in the scripts directory. If not, run:

$skillScripts = "$env:USERPROFILE\.agents\skills\video-transcript\scripts"
if (-not (Test-Path "$skillScripts\node_modules\docx")) {
    Push-Location $skillScripts
    npm install
    Pop-Location
}

Step 1 — Download subtitles with yt-dlp

Run in a temp directory (use $env:TEMP\vt_ on Windows):

$tmp = "$env:TEMP\vt_$(Get-Random)"
New-Item -ItemType Directory -Force $tmp | Out-Null

YouTube: 

# Try manual subs first, fall back to auto-generated
yt-dlp --skip-download --write-subs --write-auto-subs --sub-langs "en,zh-Hans,zh-Hant,zh" --convert-subs srt -o "$tmp\sub" ""

Bilibili: 

yt-dlp --skip-download --write-subs --sub-langs "zh-Hans,zh,ai-zh" --convert-subs srt -o "$tmp\sub" ""

Other platforms: Use the same YouTube command — yt-dlp handles most platforms automatically.

After download, list what was fetched: 

Get-ChildItem $tmp -Filter "*.srt"

Step 2 — Detect available subtitle files

Pick the best available file:

  • Prefer manual subs over auto-generated (.en.srt over .en-orig.srt or .en-auto.srt)
  • For Bilibili: pick zh-Hans or ai-zh
  • If multiple languages exist, note them all

    • If NO subtitle file was downloaded:

  • Tell the user: "该视频没有可用字幕，yt-dlp 无法提取文字内容。如需转录请使用 Whisper 语音识别（需额外安装）。"
  • Stop here.

    • Step 3 — Parse SRT to plain text

    Read the .srt file and strip all timing/index lines. Keep only the spoken text lines.

    SRT format to strip: 

    1
00:00:01,000 --> 00:00:03,500
This is the spoken text.
    2
00:00:04,000 --> 00:00:06,000
More text here.

    Output: plain text, one paragraph per subtitle block, blank lines between blocks removed (merge into flowing paragraphs). Also strip HTML tags like , , .

    Do this parsing yourself by reading the file content — no external tool needed.

    Step 4 — Translate if needed

    Detect the subtitle language:

  • If Chinese (zh, zh-Hans, zh-Hant): skip translation, one file only
  • If other language: translate the full plain text to Chinese using your own translation capability

    • Translation guidelines:

  • Produce natural, readable Chinese — not word-for-word
  • Preserve paragraph structure
  • Keep proper nouns, technical terms transliterated or explained inline if needed
  • Do NOT add commentary or summaries — pure translation only

    • Step 5 — Generate .docx files

    Use the bundled script. The script path is: ~/.agents/skills/video-transcript/scripts/make_docx.js

    Get the video title from yt-dlp output or use a sanitized version of the URL as fallback.

    For non-Chinese video (two files): 

    # Original
node "~/.agents/skills/video-transcript/scripts/make_docx.js" "$tmp\transcript_original.docx" " - Original" ""
    Chinese translation
    
node "~/.agents/skills/video-transcript/scripts/make_docx.js" "$tmp\transcript_zh.docx" " - 中文译稿" ""

    For Chinese video (one file): 

    node "~/.agents/skills/video-transcript/scripts/make_docx.js" "$tmp\transcript_zh.docx" " - 讲稿" ""

    For long texts, write content to a temp .txt file first and pipe it: 

    $plain | Out-File -Encoding utf8 "$tmp\content.txt"
Get-Content "$tmp\content.txt" -Raw | node "~/.agents/skills/video-transcript/scripts/make_docx.js" "$tmp\transcript_original.docx" ""
