Publish real-world footage without exposing the people who never agreed to be in it.
Safe Cut works out who's part of your story and hides everyone and everything else: passers-by, children, number plates, private screens. You approve every decision.
Precomputed result. Staged demo. Everyone shown signed a release (a guardian signed for the child).
How it works
Muse Spark decides who
Muse Spark watches the clip, reads who said what (from Muse Voice Transcribe), and rules on each person and object SAM 3.1 has labelled: part of the story, or not.
SAM 3.1 keeps them hidden
SAM 3.1 keeps each hidden person and item covered through the clip. Anyone the tracker loses and finds again starts hidden. Anything uncertain stays hidden.
An audit checks the render
Before anything is published, Meta's EgoBlur checks the final render for faces and number plates, and a second Muse Spark pass tries to read or recognise anything left. Any leak it can fix is covered and recorded on your privacy receipt; anything it can't fix stops publishing.
- SAM 3.1 finds and numbers every face, person, plate, screen and document
- Muse Spark rules on each number three times, with the transcript as evidence
- Muse Spark names anything SAM missed; SAM 3.1 tracks it as a new number
- The render covers everything not kept clear
- The audit checks the render; any leak is covered and checked again
Every decision keeps its evidence: the numbered keyframe, the three rulings and what was said. You see all of it under “Why?” before anything is published.
