How to blur the background of a video
Open a video of a person and Mastershot finds them in every frame, on your device. The background behind them is blurred and they stay sharp, like a phone's portrait mode or a call's background blur. Save it as an MP4 with its sound. There's no watermark and no limit on length.

What to expect
- Supported inputs
- Videos this browser can read, with a person in them.
- What happens
- A segmentation model marks the person in each frame, and the edges are cleaned against the full picture so hair and shoulders follow their real outline. Everything behind them is blurred, and the video is saved as an MP4 with its sound.
- Limits
- It finds people, not objects, pets, or products. A busy background or a person far from the camera can leave a soft edge around them, so check the preview before you save.
