How to change the background of a video
Open a video of a person and Mastershot finds them in every frame, on your device. Choose a picture to put behind them, or a plain color or a blur, and save the video as an MP4 with its sound. You don't need a green screen, there's no watermark, and there's no limit on length.

What to expect
- Supported inputs
- Videos this browser can read, with a person in them. For the new background, a PNG, JPEG, or WebP picture.
- 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. The new background is drawn behind them, 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 rough edges, so check the preview before you save.
