The Pro Capture Dual SDI 4K Plus captures two independent channels of SDI video through eight HD-BNC connectors — four rated to 3G-SDI and two each stepping up to 6G-SDI and 12G-SDI — so each channel can be wired as a single 12G-SDI link, a dual 6G-SDI link, or a quad 3G-SDI link to match the source. The card is a low-profile PCIe Gen2 x8 add-on, built to handle input resolutions up to 4096×2160 with 10-bit video processing and embedded audio extraction of up to eight mono channels at 48kHz. It's compatible with Windows, macOS, and Linux, with an SDK for all three and Magewell's Capture Express software included for straightforward recording and monitoring. Eight HD-BNC to BNC cables are included, along with a 2-year warranty.
