[FAQ](/en/other/faq.md)

### Current versions (VCam 0.13 or later / VCam2D)

* Lip sync might stop working when connecting a microphone like AirPods while VCam is running.
  * **Solution:** Please re-select the lip sync mode after connecting the microphone. Alternatively, restart VCam.
* The accuracy of emotion (smile, etc.) estimation is low.
  * **Solution:** If you get unintended expressions, turn off "Estimate emotions with the microphone or camera" in the "Experiment" tab, and switch expressions with the expression buttons or shortcuts instead.
* Combining the expression button with blinking and lip motion can distort the expression. (VCam)
  * **Solution:** When creating the blend shape for the VRM file, make sure that combining A and Blink with other expressions won't cause distortions.
* Screen flickers in Zoom.
  * **Solution:** Reduce the FPS in the "Rendering" tab or the camera FPS in the "Tracking" tab. (It's possible that the tracking or screen update processing isn't keeping up.)
