New for NAB 2023 is lip-sync measurement in the cloud. Attendees will be able to see a live demonstration of a file-based version of MatchBox.

MatchBox is now widely recognised as an industry standard in lip-sync measurements, and the latest MatchBox Glass iPhone app makes it even simpler to very quickly line up each camera feed. With remote productions like major sports sending very large numbers of feeds back to the central control room, managing lip-sync is critical.

The latest addition to MatchBox is the ability to measure end-to-end latency over a broadcast path. Given the need for minimising latency, Hitomi now recommends using MatchBox Latency to establish the delay over each circuit, before using MatchBox to synchronise pictures and sound. The same MatchBox analyser provides highly accurate readings of latency and lip-sync shift, ensuring precision alignment based on data rather than trying to match them by eye.

With the rapid growth in remote production and IP contribution, these simple and cost-effective tools are more in demand than ever.
