Video Intelligence

Download videos and get transcripts, summaries, or metadata from YouTube, TikTok, Instagram, and X (Twitter). Use when the user shares a video URL and wants a transcript, summary, key points, quotes, or to download the video. Triggers on phrases like "transcript this video", "summarize this YouTube video", "what does this video say", "download this TikTok", "get captions from", or any video URL from youtube.com, youtu.be, tiktok.com, instagram.com, x.com, twitter.com. Requires: yt-dlp, python3, curl. Optional: ffmpeg (for TikTok/Instagram/X audio), OPENAI_API_KEY (Whisper fallback — uploads audio to OpenAI).

video-intel

Downloads videos and extracts transcripts using yt-dlp (captions) with OpenAI Whisper fallback.

Required Dependencies

Dependency	Purpose	Required?
yt-dlp	Fetch captions and download audio/video	✅ Always
python3	Parse VTT/SRT caption files	✅ Always
curl	Call OpenAI Whisper API	✅ For Whisper fallback
ffmpeg	Extract audio from TikTok/Instagram/X	⚠️ Non-YouTube only
OPENAI_API_KEY	Authenticate with OpenAI Whisper API	⚠️ Only if captions unavailable

Install binaries:

bash

# yt-dlp
curl -L https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp -o ~/bin/yt-dlp && chmod +x ~/bin/yt-dlp

# ffmpeg (Debian/Ubuntu)
sudo apt install ffmpeg

⚠️ Privacy Notice — OpenAI Audio Upload

When captions are unavailable (common for TikTok, Instagram, X), the script downloads the audio and uploads it to OpenAI's transcription API (https://api.openai.com/v1/audio/transcriptions). This means:

• Audio content leaves your machine and is sent to OpenAI
• Requires OPENAI_API_KEY to be set
• If you don't want external transmission: don't set OPENAI_API_KEY, or use a local transcription model

YouTube videos almost always have captions and will not trigger an upload.

Workflows

Get transcript

bash

~/.openclaw/skills/video-intel/scripts/video-intel.sh transcript <url>

• YouTube: uses built-in captions/auto-subs (fast, no audio download or external upload)
• TikTok/Instagram/X: downloads audio → uploads to OpenAI Whisper for transcription
• Preferred language: --lang pt for Portuguese

Get video info

bash

~/.openclaw/skills/video-intel/scripts/video-intel.sh info <url>

List available caption tracks

bash

~/.openclaw/skills/video-intel/scripts/video-intel.sh captions <url>

Download video

bash

~/.openclaw/skills/video-intel/scripts/video-intel.sh download <url> [--format audio|720p|best]

After getting transcript

• Summary: Summarize in 3-5 bullet points
• Key quotes: Extract most notable quotes
• Full summary: Write a paragraph summary with context
• Translation: Translate to the user's language if different

Notes

• YouTube auto-captions are usually available even without ffmpeg
• TikTok/Instagram/X require ffmpeg for audio extraction
• Large videos (>25MB audio) may hit OpenAI's file size limit — use --format audio to get a smaller mp3
• Output cached in /tmp/video-intel/ by default
