Video capture advances to legacy analogue signals with interface card

While high definition, digital signal formats - and more recently 4K Ultra HD - now dominate the professional production landscape, standard definition analogue video transport continues to be important in some countries and in older facilities where legacy infrastructure has not yet been upgraded.

Meanwhile, many users still have large libraries of analogue videotapes, such as VHS, that have not yet been digitised. The Pro Capture Hexa CVBS, Magewell's second generation of analogue PCIe capture card, enables users to cost effectively convert analogue source signals into high quality digital video and audio data for recording or processing with the latest software.

"Customers using older analogue signal formats should not be restricted in what they can do with that video and audio," said James Liu, VP of Engineering at Magewell. "The Pro Capture Hexa CVBS makes the latest advances in our Pro Capture line available to these users, reliably digitising their sources while enabling them to take advantage of all popular Windows, Mac and Linux software applications."

FPGA-based video processing on the Pro Capture Hexa CVBS provides high quality de-interlacing, image adjustments, scaling and PAL/NTSC frame rate conversion without tasking the host system's CPU. The new model also adds powerful features not available on Magewell's earlier-generation analogue capture card, including graphic overlay, support for CEA-608/EIA-608 closed captions, and ultra low latency as little as 64 video lines.

Input sources can be fed to multiple software applications concurrently, each with independent control of video resolution, frame rate and processing. Multiple Pro Capture cards can be used in the same host system for even greater multi-channel capture density, while the powerful Pro Capture SDK lets third-party developers directly integrate the advanced capabilities of the Pro Capture Hexa CVBS into their own software applications and turnkey solutions.
