Magewell’s USB Capture Family Grows with Addition of New USB Capture SDI 4K Pro

Magewell is expanding its popular USB Capture family with the launch of the new USB Capture SDI 4K Pro, which will be showcased at the 2025 NAB Show. This compact plug-and-play device allows PCs to capture SDI video signals up to 4K resolution at 60 frames per second through a USB 3.2 Gen 2×2 interface. It’s designed for minimal CPU load and doesn’t require an external power source, making it ideal for IT professionals and AV integrators looking for efficient and high-quality video capture.

The device supports a wide range of formats—including 12G-SDI and high frame rates up to 240fps—and captures both embedded and analog audio. It’s compatible with Windows, macOS, Linux, and ChromeOS, with automatic signal detection and driver-free setup for seamless use. Magewell’s free utility software also allows users to fine-tune settings and update firmware. Visitors can check it out at NAB stand N1971 and see how it fits into professional AV workflows.

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 4096×2160 (including 3840×2160 Ultra HD) at 60fps with 4:2:2 chroma fidelity via the USB 3.2 Gen 2×2 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 2×2 connection for maximum performance.
