Magewell Pro Capture HDMI 4K PCIe Capture Card (11120)

Pro Capture HDMI 4K is the straightforward one-slot answer for a single 4K HDMI source. It captures up to 4096 x 2160 with the audio embedded on the same cable, which covers UHD and DCI 4K cameras, 4K media players, and modern computer output that an HD card would have to down-scale before it reached the recorder.

The PCIe Gen2 x4 interface supplies the bandwidth that full-raster 4K needs, and on-card scaling, color-space conversion, and de-interlacing let you hand a smaller frame to the encoder when the stream does not need 4K, without a software resize. It enumerates as a standard video device on Windows, Linux, and macOS. A low-profile bracket ships with the card, and the Mini Repeater 4K HDMI is available separately when the input cable run is long enough to be marginal.
