USB capture for Ultra HD

Marking its IBC debut, Magewell is showcasing the USB Capture 4K Plus external video capture device. The company claimed these devices are the easiest and most reliable way to bring 4K video signals into software applications for broadcast production, live streaming, encoding, interactive productions, medical imaging and more.

The devices enable all types of computers, including laptops, to capture professional video and audio signals through a standard USB 3.0 interface, with driver-free installation and automatic input detection.

Two models provide a choice of input connectivity. The USB Capture SDI 4K Plus captures video up to 4096×2160 at 30fps over its 6Gbps SDI interface, while the USB Capture HDMI 4K Plus supports 4K inputs up to 60fps via HDMI 2.0 connectivity, capturing them at 30fps.

Both models offer loop-through connections, reducing workflow costs and complexity by enabling source signals to be sent simultaneously to additional displays or equipment without the need for external splitters or routers. The devices support embedded audio as well as a separate analogue audio input and output for capture and monitoring.

High-quality video processing such as up/down/cross-conversion, graphic overlay and image adjustments are performed by the devices’ on-board FPGA, maximising host system CPU availability for third-party software.
