Magewell’s Pro Capture SDI 4K Plus is a PCIe video capture card designed for professional use. With 4 SDI connectors supporting Quad-link 12G-SDI, it allows you to capture one channel of Ultra High Definition Video at 4096x2160p resolution. Connect your SDI signal output direct to the card from your Camcorders, Playback Devices, Monitoring Devices or Broadcast Decks. The card also features a range of built-in processing functions such as cropping, scaling, format/frame rate conversions, and deinterlacing etc.



Multiple Pro Capture cards may be installed per system, limited only by the number of physical PCIe slots in your system. The number of Output streams are unlimited, and settings for each stream can be independently customised and adjusted. Works with Windows, Mac and Linux Operating Systems, supports multiple APIs for Windows and Linux, and provides Windows SDKs for ease of integration.



Please note that while the Pro Capture SDI 4K Plus has 4 external SDI connectors, they are for dual or quad-link configurations. The card accepts only one video channel input.
