AI Disclosure Rules (Don't Skip This!)
YouTube requires disclosure when your video:

- Alters footage of real events
- Generates realistic scenes that didn't happen
You do NOT need to disclose for:
- B-roll / background footage
- Stylized / clearly unrealistic visuals
- AI voiceover of your OWN voice
- AI-assisted editing
Best practice: Always add "Made with AI" disclosure even if not required. Trust signal for 2026 audiences.
