Magewell Pro Capture SDI One-Channel PCIe Capture Card (11050)

Pro Capture SDI is the BNC version of Magewell's single-channel card. It accepts SD, HD, 3G, and 2K SDI up to 2048 x 1080 with the audio embedded on the same coax, which is how most broadcast and staging plants already move signal - one locking cable per camera, over a run length HDMI cannot manage.

The card fits a PCIe Gen2 x1 slot and appears to the host as a standard video device on Windows, Linux, and macOS, so streaming, recording, and conferencing software addresses it directly. Scaling, color-space conversion, and de-interlacing are done in hardware on the card, keeping the host CPU free for encoding rather than for format conversion.
