New model leverages 20 Gbps USB 3.2 Gen 2x2 interface to capture 12G SDI without a driver or external power

NANJING, China — April 2^nd, 2025 — Magewell, developer of innovative, high-performance video I/O and IP workflow solutions, will debut their new USB Capture SDI 4K Pro at the 2025 NAB Show. This small, plug-and-play device enables PC’s to capture SDI signals up to 4K resolution at 60fps via standard USB 3.2.

USB Capture SDI 4K Pro is the newest in a long line of high-quality USB Capture products. Able to 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 seamless video capture with minimal CPU usage and no external power source.

Boasting a long list of capabilities, the USB Capture SDI 4K Pro does more than just 4K. 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. The full product specification can be found at https://www.magewell.com/products/usb-capture-sdi-4k-pro.
