Magewell Pro Capture Quad HDMI Four-Channel PCIe Capture Card (11100)

Pro Capture Quad HDMI is the density card: four HDMI inputs, each a full independent capture channel with its own embedded audio, on one PCIe Gen2 x4 board. A four-camera lecture room, a multi-angle esports capture rig, or a courtroom recorder can run from a single slot in a single machine, which is usually cheaper and quieter than four machines or four USB devices on a hub.

Each channel captures up to 2048 x 2160. Hardware scaling, color-space conversion, and de-interlacing run on the card rather than in software, so a four-channel record stays within CPU budget on a mid-range workstation. The card enumerates as standard video devices on Windows, Linux, and macOS, so recording and streaming applications see all four inputs directly.
