Frequently Asked Questions
- How does AI background blur work?
- our AI analyzes each frame to create a precise mask of the subject. The background is then blurred while the subject remains sharp — similar to portrait mode on a phone but for video.
- Do I need a green screen?
- No — the AI detects subjects automatically in any scene. It works best with clear foreground subjects (people, animals, objects) against a distinct background.
