Hitomi Broadcast, market leader in audio/video alignment and latency tools, is sending its team to the Media Production & Technology Show (stand J30, Olympia London, 10 – 11 May). They will be showing how simple it is to identify one of the most irritating – and growing – problems in live production: maintaining proper synchronisation between video and audio. As remote production and multiple contributions become a central part of today’s television, lip sync is a greater concern than ever.
Hitomi has the simplest, most precise and most used solution for lip sync measurements: MatchBox. To enable camera-to-output measurement, the MatchBox Glass iPhone app makes it even simpler to very quickly set up each circuit, based on precision data rather than eyes and guesswork.
With remote productions like major sports sending very large numbers of feeds back to the central control room, managing lip sync is critical, but so too is understanding and controlling latency. MatchBox software now includes the ability to measure end-to-end latency over a circuit. Use MatchBox Latency to establish the delay over each circuit, then use MatchBox to synchronise pictures and sound.
“Everyone is aware that lip sync errors are really annoying, whether it is speech not matching the mouth or the sound of ball and bat coming a long time before you see the stroke,” said Russell Johnson, broadcast director at Hitomi. “MatchBox gives an absolutely precise measurement of latencies and delays, and events like MPTS means we can show visitors, in just a few moments, how simple it is to use.”
Hitomi can be found at MPTS 2023 on stand J30. Full information on the company and its products is at hitomi-broadcast.tv, and a quick guide to aligning latency and lip sync is at https://youtu.be/QSYurg_Oy0g.
