Magewell has introduced the USB Capture SDI 4K Pro, which is able capture SDI signals up to 4096x2160 (including 3840x2160 Ultra HD) at 60fps with 4:2:2 chroma fidelity via the USB 3.2 Gen 2x2 interface.
The USB Capture SDI 4K Pro provides video capture with minimal CPU usage and no external power source.
The unit can accept many different video formats up to 12G or frame rates up to 240fps. Along with video, the device can capture 2-channels of embedded audio or analog audio via a 3.5mm Line In interface. Embedded audio can also be extracted and output via the 3.5mm Line Out interface. The unit is FPGA-based and makes no demands on the PC’s CPU, but does require a 20 Gbps USB 3.2 Gen 2x2 connection for maximum performance.
