Introduction

Background blur helps focus attention on the subject and gives reaction videos a cleaner, more professional feel. It can also be combined with face or plate detection to protect privacy.

How to Apply Background Blur

1. Use an automated tool to detect subject regions and generate a blurred background.
2. Adjust blur strength to balance aesthetics and context.
3. If necessary, combine with face/license-plate blur to protect bystanders.

Conclusion

Properly applied background blur enhances production value and can be part of a privacy-first workflow for content creators.
