Sync-One2 gives you, in real-time, the auto-video (lipsync) delay/error in a system such as ProTools or Premiere Pro, Digital Audio Workstation (DAW), a digital or home cinema, an installed AV system, or anywhere where the audio and video take different paths.  You see the error in milliseconds and frames.  Automatically calculated statistics show you the true status of a system.

Trying to check any system manually simply isn't accurate, wastes time, and relies on guessing with trial and error adjustments.

Using a Sync-One2 is simple, fast, and accurate.  A system can be checked and corrected in just a few minutes.  You can find details of common sync problems in the FAQ.
