Video Transcript Downloader is an Agent Skill for documents published in the LeoYeAI/openclaw-master-skills repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Download videos, audio, subtitles, and clean paragraph-style transcripts from YouTube and any other yt-dlp supported site. Use when asked to “download this video”, “save this clip”, “rip audio”, “get subtitles”, “get transcript”, or to troubleshoot yt-dlp/ffmpeg and formats/playlists.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/LeoYeAI/openclaw-master-skills/blob/HEAD/skills/video-transcript-downloader/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/video-transcript-downloader, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

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

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

Transcript (default: clean paragraph)

./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

./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):

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

Download a specific format id (example):

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

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

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

Troubleshooting (only when needed)

  • Missing yt-dlp / ffmpeg:
brew install yt-dlp ffmpeg
  • Verify:
yt-dlp --version
ffmpeg -version | head -n 1
