# 10. Using the Filter Function

## **How to Configure Filters**

**Settings > Filter Tap -> Preset -> Process Mode / Filter Type**

1. In versions before v1.3.1, the settings related to Process Mode and Filter Type, which were divided into USB Camera, Video File, and CSV Play under the Actor tab and Experimental, have been unified under the Filter tab.

2. The default preset is set to "Stable," with Process Mode set to LIVE\_STREAM/VIDEO and Filter Type set to "None." This mode ensures stable output without any jitter even without filter settings.

3. In fast-talking situations where the responsiveness of lip movements is crucial, the Stable mode may have some limitations. Therefore, while keeping the existing Average and Butterworth modes unchanged, the Kalman filter has been upgraded to allow for two different settings to be applied per BlendShape.

4. Among the presets, "Balanced" and "High Performance" are configured to increase responsiveness. "Custom Ex01" is set to further reduce the jitter in BlendShapes related to the brow and eye while maintaining responsiveness for other parts.
