Magewell to Launch 4K USB Video Capture Devices This Week

Magewell will unveil new 4K models in its USB Capture Plus series of external video capture devices this week.

Like existing Magewell USB video “ingest” solutions, the newest USB Capture Plus models enable all types of computers including laptops to capture professional video and audio signals through a standard USB 3.0 interface, with no additional power source required. Available with SDI or HDMI inputs, the 4K USB Capture Plus devices capture resolutions up to 4096×2160.

The new USB Capture SDI 4K Plus captures 4K video at 30 frames (@30Hz) per second over its 6Gbps SDI interface, while the USB Capture HDMI 4K Plus supports 4K inputs up to 60fps (@60Hz) via HDMI 2.0 connectivity, but scales them at 30fps. 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. Both models offer loop-through connections.

Both new 4K USB Capture Plus devices support embedded audio in the SDI or HDMI input signal, as well as separate audio inputs and outputs for capture and monitoring: line-level analog input and output connections on the USB Capture SDI 4K Plus, and an analog microphone input and stereo headphone output on the HDMI model.

Like Magewell’s HD models, the new 4K USB Capture Plus devices feature FPGA-based video processing, for deinterlacing, up/down conversion and image controls while not affecting CPU availability for third-party software. FPGA-based audio processing featuring ASRC technology delivers superior USB audio handling, while the included USB Capture Utility software gives users advanced control of processing settings and access to detailed status information.
