🎬 YouTube AI Editor (v1.0.14)

⚠️ Security Notice

This skill may trigger security warnings due to legitimate automation features:

Required Capabilities:

• API Keys: Requires OPENAI_API_KEY (mandatory for Whisper/GPT-4) and NANO_BANANA_KEY (optional for AI image generation)
• Subprocess Execution: Uses ffmpeg for video processing (standard video editing tool)
• Cross-Skill Integration: Calls nano-banana-pro skill for AI image generation (optional feature)
  • Only executes if nano-banana-pro is installed by user
  • Uses fixed script path resolution with timeout protection
• File I/O: Reads user-specified avatar/font files and writes output files (thumbnails, transcripts) to working directory

Security Measures:

• YouTube URL validation (blocks localhost/private IPs)
• HTML-escaped text rendering
• Subprocess timeouts (900s max)
• Fixed script paths (no arbitrary code execution)

All code is open source and auditable. Review nano-banana-pro separately if using image generation features.

Option 1: Fully Automated (Pirate Lobster Mode)

The AI will generate a Pirate Lobster character doing something related to your video, while keeping the original character design consistent.

uv run scripts/process_video.py --url "https://youtube.com/watch?v=YOUR_VIDEO_ID"

  --avatar "/path/to/my_face.jpg"
