Controls and additional tasks
Detection Confidence and Minimum Face Size decide which faces are accepted. Tracking, hold, and detection-rate settings control how masks follow movement.
Effect settings
| Setting | Use and limits |
|---|---|
| Style | Soft Blur, Pixelate, or Solid Mask. Only the relevant style controls are shown. |
| Amount (%) | Effect coverage/strength, 0–100; default 100. |
| Blur Radius (pixels) | Soft Blur size, 1–80; default 24. Larger blur obscures more detail. |

| Mask Color | Solid Mask fill color; default opaque black. |
| Mask Shape | Ellipse or Rectangle; default Ellipse. |

| Edge Softness (%) | Soften the mask boundary, 0–50; default 10. |
| Detection Confidence | Minimum accepted detection confidence, 0.1–0.99; default 0.8. Higher values reject more uncertain detections. |
| Minimum Face Size (pixels) | Ignore faces smaller than this size, 4–512; default 24. |
| Tracking Smoothing | Smooth tracking changes, 0–0.9; default 0.35. |
| Hold Missing Faces (ms) | Keep the last mask briefly after detection is lost, 0–2000 ms; default 250. |
| Detection Updates per Second | Detection refresh rate, 1–30; default 10. |
If something is wrong
If a face is missed, review its size, visibility, confidence threshold, and mask expansion. Automatic detection does not guarantee every face is covered.
