Magewell Doubles 4K Capture Density with New Dual-Channel UHD Cards

Magewell has announced two powerful, dual-channel 4K models in its Pro Capture family of PCI Express capture hardware.

Supporting the accelerating adoption of 4K video in professional production and A/V workflows, the new cards will make their industry debut at NAB Show New York.

Magewell's Pro Capture cards deliver high-quality video and audio capture for end-users, systems integrators and OEM developers. The newest models continue to provide these benefits while also enabling the capture of two channels of Ultra HD video with embedded audio on each single card.

Unlike most other multi-channel offerings, which limit 4K capture frame rates to just 30fps, the new dual-channel Pro Capture 4K cards support video resolutions up to 4096 x 2160 at full 60fps over high-speed PCIe 3.0 x4 bus interfaces. 

The Pro Capture Dual HDMI 4K Plus features HDMI 2.0 inputs, while the Pro Capture Dual SDI 4K Plus flexibly supports single-link 12G-SDI, dual-link 6G-SDI or quad-link 3G-SDI connectivity.

Further, both inputs can be used simultaneously with independent resolutions, frame rates and processing settings. Each source channel can also be routed to multiple software applications in parallel, again with varying capture parameters for each program.

The new Pro Capture card models perform functions such as high-quality up/down/cross-conversion, image adjustments and graphic overlay in an on-board FPGA with zero impact on the host system CPU. This maximises processor availability for third-party software — already a significant resource savings given the quadrupled processing requirements of 4K video compared to HD formats, and doubly beneficial when processing two Ultra HD sources at once.
