Validating the AV sync of commercial installations spaces was time-consuming and inaccurate, even with a keen eye.  So Sync-One2 was created to solve this problem when no simple, off-the-shelf solution was available.

Some curious people wondered what was happening when watching an early version of Sync-One2.  So, after a brief explanation, they asked if they could have one too.  So in late 2013, Sync-One2 was made available to others.

Version 2 was released in August 2018, containing features requested by those in Post Production, film, and the TV industry.  An audio input port and an API interface with even greater accuracy.

Sync-One2 has become the reference tool to verify AV sync accurately and used by many household names in Post Production, Digital Cinemas, and TV networks worldwide.

Also available from Harkwood Services is cmdBridge, a real-time command protocol translator designed to reduce the costs of AV system maintenance, especially where the control system source code is unavailable.
