The new USB Capture SDI 4K Plus from Magewell captures 4K video at 30 frames per second over its 6Gbps SDI interface. 4K inputs with 4:4:4 or 4:2:2 color sampling are automatically converted to 4:2:0 for capture in the NV12 or I420 color space formats, to fit within the bandwidth available in the USB 3.0 standard.
