How to blur moving faces in a video on iPhone
Blurri can scan a video for faces, group detections by person and track selected people. Review the complete rendered video because movement and occlusion can interrupt automatic tracking.
App used in this guide: Blurri ↗
Before you begin
Start with a short clip to learn the workflow. Identify people who enter later, turn away or reappear after leaving the frame, since they may require closer checking than someone who stays centered.
Step by step
- Open a video in Blurri and run its face scan.
- Review the detected people and choose which should be blurred.
- Select a rendering mode and let processing finish.
- Play the exported result from beginning to end before sharing.
Check the result
Pause at scene changes, overlaps and fast movement. Check early and late frames, not just the middle of the clip where detection may be easiest.
Limits and troubleshooting
Tracking is not guaranteed in every frame. If a face becomes visible in the result, revise the available selections and render again, or withhold the clip when you cannot conceal the person reliably.
