# Background Removal / Cutout

> Use AI to remove the background of your video or overlays and replace it with other images

## How It Works

To remove and replace the background of a video or overlay:

1. Tap on your video or overlay in the timeline
2. Tap on **Cutout**
3. Select a new background (setting a custom background for an overlay is not possible)

<Info>
  Tap the **+** icon to set custom stock images or photos from your camera roll as the background.
