Most important principle: You must respect the privacy of people in your video. Publishing video that clearly shows other people's faces without their consent is something you are obligated to avoid — both ethically and legally. Face-blur isn't optional in those situations — it's required when you don't have explicit consent.
The good news: AI can now automatically detect and blur faces in video — quickly, accurately, without manual frame-by-frame editing.
When Do You Need AI Face-Blur?
- Video shot in public spaces where people pass by (markets, streets, events)
- Interview footage where the subject doesn't want to be identified
- Event footage that includes children
- Any video showing faces where you don't have clear consent to publish publicly

Practical Workflow: Blur Faces Before Publishing
- Download the video to your computer (if downloading from social media, use Klypio)
- Upload to your chosen AI face-blur tool
- Let the AI automatically detect and blur faces
- Review the result — check if any faces were missed
- Export the blurred video and publish to your channel
Legal and Ethical Notes
- Face-blur is a required step when you don't have the consent of people in the video
- In many countries, publishing identifiable footage of others without consent may violate data protection laws (GDPR in the EU, PDPA in Vietnam and Southeast Asia)
- Even when not legally required in a specific situation, doing the ethical thing is always the better choice
