Capture and playback at the same time
This compact Thunderbolt 4 interface combines a 12G-SDI input with separate fill, key and monitor outputs. It is built for instant replay, graphics and ingest in DaVinci Resolve.
Replay without a bulky rack
Connect the input to a switcher multiview output and use the recording immediately for slow-motion or repeat playback. The unit stays compact and is powered directly from the Thunderbolt port.
Three independent SDI paths
Two program outputs provide fill and key for titles or automated graphics, while the third is a dedicated monitor output. All connections use professional 12G-SDI.
Built for current computers
Connection requires a Thunderbolt 4 USB‑C port; the interface is powered directly by the computer.
