Magewell’s Pro Capture SDI card is designed as an effective solution for capturing high-resolution video inputs to your Desktop PC. Fitting into a single PCIe 2.0 slot, it accepts up to 4 SDI inputs (depending on the variant) at a maximum resolution of 2048×2160. The card also features multiple colour sampling modes, at 10/12-bits, and a top frame rate of 144 fps. Furthermore, the Pro Capture SDI comes with a range of built-in video processing tools such as cropping, scaling, and format conversion 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.



Comes in single, dual and quad input variants; the single and dual input cards feature loop-through connectors for redundancy or additional connections to other devices.
