Style your camera overlay with border presets, adjust its position and framing, remove your background, or swap in a static avatar.

Who this is for
Anyone who recorded with a camera overlay and wants to style it — change its border, move it, remove the background behind them, or replace it with a static image entirely.
Before you start
You need a recording that includes a camera track. Camera styling is applied in the editor, not during recording, so you can change your mind after the fact — except swapping to a static avatar, which replaces the live camera feed for that clip.
Steps
Select the camera clip on the timeline. The camera styling controls appear in the inspector.
Choose a border style. Pick from 5 available border presets.
Adjust position and framing. Drag the camera overlay to any corner or edge of the frame, and resize or reframe how tightly it crops around you.
Adjust cursor size and opacity, if your recording includes a visible cursor, from the same panel.
Turn on Remove Background to drop your real background out of the shot. This uses Apple’s native on-device subject-segmentation — the same technology behind Remove Background in Preview, Photos, and Keynote — so it runs entirely on your Mac. When enabled, the border traces your silhouette instead of framing a rectangle.
Or swap to a static avatar. Open the avatar picker to replace your live camera feed with a static image — either a photo or an exported Memoji/Animoji sticker — for moments you’d rather not be on camera.
What you should see
The camera overlay updates live in the preview as you change border, position, and background settings — with Remove Background on, only you (not your room) appear inside the styled border.
Common issues
Remove Background looks rough around the edges — this depends on lighting and contrast between you and your background; try a more evenly lit setting for cleaner edges.
Border still shows a rectangle after enabling Remove Background — give the preview a moment to reprocess, or scrub the timeline slightly to force it to refresh.
Avatar picker option is grayed out or the swap didn’t apply — avatar swaps apply per clip; make sure you have the correct camera clip selected on the timeline before opening the picker.
Camera controls aren’t showing at all — the selected clip may not include a camera track; confirm the recording had Camera enabled (see How to record your screen, camera, and mic).
