Pixelate faces in a video with mosaic
Mosaic replaces facial detail with enlarged color blocks. FaceBlur tracks each detected face and applies the selected block size and safety margin throughout the clip.
Mosaic versus blur versus solid
| Effect | Control | Use |
|---|---|---|
| Mosaic | Strength changes block size | Recommended default for redaction |
| Soft blur | Strength changes blur radius | Less intrusive visual treatment |
| Solid | No strength setting | Maximum facial concealment |
Adjust mosaic safely
Raise strength until eyes, nose, mouth, and distinctive facial detail are not readable at normal playback and when paused. Increase the safety margin to cover the forehead, chin, ears, and movement between detections. Settings apply equally to every detected face.
Where pixelation can fail
- A weak block size can leave recognizable structure.
- A mask that is too tight can expose facial edges during motion.
- Profiles, distant faces, occlusion, or rapid cuts can cause detection misses.
- Voice, clothing, tattoos, location, or context can still identify a person.
Pixelation is not a guarantee of anonymity. For sensitive footage, consider solid cover, remove audio, and inspect the exported file carefully.
Apply mosaic automatically
Choose a clip, preview every detected mask, and export without a watermark.
