Magewell Pro Capture Quad SDI Four-Channel PCIe Capture Card (11090)

Pro Capture Quad SDI takes four BNC feeds into one PCIe Gen2 x4 slot, each channel independent and each carrying its own embedded audio. That is the shape of a four-camera ISO recorder, a multi-court or multi-room capture appliance, or a redundancy rig where two program feeds and two clean feeds land on the same machine.

All four inputs accept SD, HD, 3G, and 2K SDI up to 2048 x 1080. Scaling, color-space conversion, and de-interlacing are handled on the card, so the CPU cost of four simultaneous captures stays manageable. The card enumerates as standard video devices under Windows, Linux, and macOS, so existing recording and streaming software addresses all four channels without special integration.
