# Blur the background of a video

> Drop in a talking-head or webcam clip. The room behind you blurs like a portrait lens and you stay sharp. Nothing is uploaded for it.

Blur everything behind the person in a video you already shot, like a portrait lens. AI finds the person on every frame, in your browser. Free.

## How it works

1. **Drop in your video** — A webcam recording, an interview, a selfie video.
2. **The background blurs** — A small AI model loads the first time, then it runs live.
3. **Set how much** — From a light softness to a strong blur. Darken or recolour the background instead if you prefer.

## Why CutLuma for this

- **After the fact** — Fix a messy room in a video you have already recorded.
- **Stays on your computer** — The person is found in your browser, not on a server.
- **More than blur** — Black-and-white, dark or flat-colour backgrounds, an outline or a glow around you.

## FAQ

**Is it free?**

Yes, it is part of the free editor.

**Can I blur the background while recording?**

Yes. Camera looks in the recorder blur or replace the background before the video is recorded.

**Why is there a halo around me?**

The cut-out edge is soft. Good light and a background that contrasts with your hair and clothes reduce it; a lighter blur hides it best.
