MatchBox is a state-of-the-art audio video alignment tool

Have you ever watched TV and noticed that sometimes the sound and pictures don't match up properly – the Lip Sync is off? The path from camera lens to television screen is complex and varied. For a live broadcast, it will be different every time.

It may be necessary to separate the sound and pictures at various points as they travel through the process. This is where they can encounter different delays and arrive at the destination at different times. The result of which is a “Lip-Sync Error”.

Using eye and ear alone to align the delay is very subjective as people’s perception of what is correct can be very different. What is needed, is a precise measurement tool. Hitomi MatchBox accurately measures audio and video alignment so that the exact amount of correction can be applied.
