PRIVACY GUIDANCE
Automatic detection helps, but review still matters
Face detection can become less reliable when a person turns away, moves quickly, is partly covered, appears very small, or leaves and re-enters the frame. Use extra face padding when privacy matters more than preserving nearby details.
For best results, play through the full preview and check the exported video once more before publishing or sending it. If you also need to remove empty borders from footage, try Remove Black Bars from Video.
QUESTIONS
Automatic Face Blur FAQ
Can this tool blur moving faces automatically?
Yes. It detects faces from video frames and matches nearby detections into short face tracks, so the blur can follow motion without manual keyframes.
Can I blur every face in a video?
Yes. All detected face tracks are blurred by default. You can also turn the effect off for a specific detected track while reviewing the video.
Why might a face be missed?
Very small faces, strong motion blur, profile angles, occlusion, poor lighting, or a person leaving the frame can reduce detection reliability. Increasing padding helps coverage but does not replace a final review.
Does Motricialy upload my video?
No video-processing upload is required. The selected video is decoded, analyzed, rendered, and recorded in your browser.
Will the exported video keep its audio?
The tool keeps the original audio when the browser exposes the audio track for local recording. If that capability is unavailable, the interface tells you before download.
What video formats are supported?
MP4 and WebM work in current Chromium-based browsers when their underlying codecs are supported. MOV compatibility depends on the codec inside the file and the browser.
