About this product
The Pro Capture Dual SDI 4K Plus is the SDI counterpart to the Dual HDMI 4K Plus LT — two fully independent 12G-SDI capture channels at up to 4Kp60 with active loop-throughs, on a single PCIe x8 card. For broadcast 4K ingest density per slot, it is unmatched.
Most commonly specified into OB trucks, 4K broadcast galleries, and high-end live-production workstations where two 4K SDI cameras need to be ingested simultaneously without taking up two card slots. Each loop-through is active, so both downstream SDI chains continue uninterrupted while capture runs.
Each channel supports the full SDI range — 12G, 6G, 3G, HD and SD — so mixed-vintage camera estates work without configuration.
