Blur what's private
Draw a box over a face, a licence plate, an address bar, a token or an inbox. The mask rides along with the clip and is baked into the export.
Region masking
macOS video editor
Blur what shouldn’t be public. Then share the video.
Faces, licence plates, street addresses, an API key or an inbox caught in a screen recording — draw a box and it is gone from the export. Trim and join clips while you are there, then export up to 4K. Everything renders on your Mac. Nothing is uploaded.

01 — What it does
Clean the video up before anyone else sees it.
A focused toolset that stays out of the way — built with SwiftUI to feel like it belongs on macOS.
Trim with precision
Drag the handles or split on the playhead. A 0.3 s minimum keeps cuts clean, and every edit is undoable.
Frame-accurateJoin & reorder
Drop several clips on the timeline, drag to reorder, and stitch them into one continuous export.

Real thumbnails and an audio waveform, with pinch-to-zoom from a bird's-eye view down to the frame.
