name: video-transcript-downloader description: "Extract, summarize, and download video/audio/subtitles using yt-dlp/ffmpeg. Use when the user requests downloads or transcripts."

Video Transcript Downloader

./scripts/vtd.js can:

• Print a transcript as a clean paragraph (timestamps optional).
• Download video/audio/subtitles.

Transcript behavior:

• YouTube: fetch via youtube-transcript-plus when possible.
• Otherwise: pull subtitles via yt-dlp, then clean into a paragraph.

Setup

Copycd ~/Projects/agent-scripts/skills/video-transcript-downloader && npm ci

Transcript (default: clean paragraph)

Copy./scripts/vtd.js transcript --url 'https://…'
./scripts/vtd.js transcript --url 'https://…' --lang en
./scripts/vtd.js transcript --url 'https://…' --timestamps
./scripts/vtd.js transcript --url 'https://…' --keep-brackets

Download video / audio / subtitles

Copy./scripts/vtd.js download --url 'https://…' --output-dir ~/Downloads
./scripts/vtd.js audio --url 'https://…' --output-dir ~/Downloads
./scripts/vtd.js subs --url 'https://…' --output-dir ~/Downloads --lang en

Formats (list + choose)

List available formats (format ids, resolution, container, audio-only, etc):

Copy./scripts/vtd.js formats --url 'https://…'

Download a specific format id (example):

Copy./scripts/vtd.js download --url 'https://…' --output-dir ~/Downloads -- --format 137+140

Prefer MP4 container without re-encoding (remux when possible):

Copy./scripts/vtd.js download --url 'https://…' --output-dir ~/Downloads -- --remux-video mp4

Notes

• Default transcript output is a single paragraph. Use --timestamps only when asked.
• Bracketed cues like [Music] are stripped by default; keep them via --keep-brackets.
• Pass extra yt-dlp args after -- for transcript fallback, download, audio, subs, formats.

Copy./scripts/vtd.js formats --url 'https://…' -- -v

Troubleshooting (only when needed)

• Missing yt-dlp / ffmpeg:

Copybrew install yt-dlp ffmpeg

• Verify:

Copyyt-dlp --version
ffmpeg -version | head -n 1
