Magewell Pro Capture Dual HDMI 4K Plus LT PCIe Capture Card (11260)

Pro Capture Dual HDMI 4K Plus LT puts two independent 4K capture channels on one board. Each HDMI input takes up to 4096 x 2160 with its own embedded audio, so a machine can ISO-record two UHD cameras, or capture a 4K program feed alongside a 4K presentation source, from a single slot.

Two simultaneous 4K streams need real bus bandwidth, which is why this card uses a PCIe Gen2 x8 interface rather than the x4 of the single-channel models. Scaling, color-space conversion, and de-interlacing run on the card, so each channel can be delivered to the encoder at the size the stream actually needs. Windows, Linux, and macOS see standard video devices. Magewell's Mini Repeater HDMI 4K is available separately for difficult input cable runs.
