The newest member of Hitomi's MatchBox family of solutions for lip-sync, MatchBox Glass is a sophisticated app that allows measurement to be made from in front of the camera on location for the ultimate in professional content.
MatchBox Glass is powerful and, like MatchBox Generator, works with MatchBox Analyser to replace the need for human intervention to test audio and video links. MatchBox Glass ensures that whatever is in front of the camera looks and sounds like it should on screen.
Making the measurement is simple and fast. The user holds an iPhone or iPad running the FREE iOS app in front of up to four cameras. At the other end, the MatchBox Analyser, which has four inputs, when enabled with the licence for Glass, can exactly measure video and audio timing differences – if any – across all four cameras.
The remote MatchBox Analyser in the OB truck or MCR looks and listens for a unique flash and audio tone generated onsite by MatchBox Glass and in approximately two seconds returns video and audio alignment and adjustment data that thus vastly accelerates the process of onsite synchronisation. This is especially useful for remote productions because it provides the ability to swiftly and accurately catch any synchronisation issues before they leave the site.

Russell Johnson explains why getting lip-sync issues right is so important in broadcasting today and demonstrates the MatchBox Glass app in practice.
With one person providing the test patterns via the Glass app in front of the camera feeding into the MatchBox Analyser back in the MCR or OB truck, near-instant alignment of lip-sync is easily achieved.
MatchBox Glass can easily measures lip-sync and latency by simply holding the device running the app in front of the camera.
As Russell shows in this video, the sensitivity of the system enables even small differences in distance between camera and microphone to be detected and almost instantaneously corrected via the MatchBox Analyser.
Another application for MatchBox Glass is to easily line up camera feeds by having an iPhone or iPad running the app in shot.
This then allows the MatchBox Analyser to make a measurement. One camera acts as the reference and then the difference is calculated.
