If you experience lag or delay in sound during your video playback, some of the speech may not seem to be captured by the charts (i.e.showing pause where there is speech, not showing pitch). Please do the following to fix the issue:

Type x264 into search bar near the Start tab > Click configure x264vfw


  • Set Preset to Fast
  • Check Zero Latency 
  • Set Ratefactor to 18.0
  • Check VirtualDub Hack 
  • Set Log level to None


Click OK to save settings.

If you still have lag in your video replay after next PitchVantage session, contact us at support@pitchvantage.com.
