mp4(default): Most compatiblewebm: Modern formatmkv: Matroska container
Example:
python scripts/download_video.py "URL" -f webm
Audio Only
Use -a or --audio-only to download only audio as MP3:
python scripts/download_video.py "URL" -a
Custom Output Directory
Use -o or --output to specify a different output directory:
python scripts/download_video.py "URL" -o /path/to/directory
Complete Examples
- Download video in 1080p as MP4:
python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 1080p
- Download audio only as MP3:
python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -a
- Download in 720p as WebM to custom directory:
python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 720p -f webm -o /custom/path
How It Works
The skill uses yt-dlp, a robust YouTube downloader that:
- Automatically installs itself if not present
- Fetches video information before downloading
- Selects the best available streams matching your criteria
- Merges video and audio streams when needed
- Supports a wide range of YouTube video formats
Important Notes
- Downloads are saved to
/mnt/user-data/outputs/by default - Video filename is automatically generated from the video title
- The script handles installation of yt-dlp automatically
- Only single videos are downloaded (playlists are skipped by default)
- Higher quality videos may take longer to download and use more disk space
Source
git clone https://github.com/davepoon/buildwithclaude/blob/main/plugins/all-skills/skills/video-downloader/SKILL.mdView on GitHub Overview
Download YouTube videos with full control over quality and format settings. It supports best, 1080p, 720p, 480p, 360p, and formats MP4, WebM, MKV, plus audio-only MP3. Downloads default to /mnt/user-data/outputs/ and playlists are skipped by default.
How This Skill Works
The tool uses yt-dlp to fetch video information, select the best streams matching your criteria, and merge video and audio when needed. It automatically installs yt-dlp if missing and handles downloads from a single video URL.
When to Use It
- You want to save a YouTube video for offline viewing at a specific quality
- You need an audio-only MP3 version for music or podcasts
- You require a specific container format (MP4, WebM, or MKV) for compatibility
- You’re targeting a specific quality like 1080p or 720p
- You want to download to a custom directory or avoid playlists
Quick Start
- Step 1: Run the script with a YouTube URL to download the video into the default outputs directory
- Step 2: Use -q to select a specific quality or -f to choose a format
- Step 3: Use -a for audio-only MP3 or -o to set a custom output directory
Best Practices
- Validate the YouTube URL before running the command
- Choose the exact quality with -q and the desired container with -f before downloading
- If you only need audio, use -a to save MP3s and conserve space
- Ensure the output directory exists and you have write permissions
- Be mindful of download sizes and network usage for high-quality video
Example Use Cases
- Download 1080p MP4: use quality 1080p with MP4 container for a high-quality video
- Download audio-only MP3: use -a to save only the audio stream as MP3
- Download 720p WebM to a custom directory: -q 720p -f webm -o /custom/path
- Download best available MP4 by default without extra flags
- Skip playlists and download a single video only
