# Tracking Settings

Tracking Settings control response, stability, smoothing, and calibration for the selected slot.

### Primary controls

* **Mouth Response** increases mouth speed at higher values.
* **Mouth Stability** adds deadband at higher values.
* **Jaw Response** increases jaw landmark speed at higher values.

### SDK smoothing

Enable smoothing by feature: **Face Position**, **Face Landmarks**, **Head Motion**, **Facial Expressions**, and **Eye Gaze**.

Disable **Facial Expressions** smoothing for the fastest mouth response. Confirm that resulting motion remains stable.

### Calibration

Use **QuickN** for a neutral reference. Use **ROM** for full expression range calibration.

Use **FixONE** only after QuickN or ROM establishes a shared neutral. Calibration requires active tracking and is unavailable with **Skip Tracking** enabled.
