Magic Mask and Depth Map as starting points
AI segmentation estimates a subject or depth relationship. It can produce useful isolation quickly, but difficult edges, motion blur, and occlusion still require judgment and cleanup.

Work through it
- Choose a short shot with a distinct moving subject. Add a dedicated node and use Magic Mask’s available selection controls on a useful reference frame.
- Track the selection through the shot and inspect the matte, particularly hair, hands, crossing objects, and the first and last frames.
- Use the mask for a subtle correction before attempting a dramatic background replacement. Repair failures with additional guidance, windows, or an alternative selection technique.
- Test Depth Map on another node for a broad spatial separation. Adjust the depth range and softness while checking that the estimated depth remains stable during movement.
Your turn
Create a gentle background-versus-subject separation in a five-second shot. Exaggerate it temporarily to find matte failures, then restore a natural strength.
