The Magewell USB Capture SDI Plus is a compact video capture dongle that allows you to record and stream UHD video to your PC wherever and whenever you need to. Connect Cameras and other professional equipment straight to the 2K-SDI input without the need for converters or adapters; and with an SDI loop through output, you can easily place the dongle anywhere in your workflow without making any drastic alterations. Additional features include Analogue Line IN/OUT Audio jacks, and a video processing toolkit that makes it convenient to crop, scale and convert formats etc.



All Magewell USB Capture dongles are powered by USB 3.0, and utilise your system’s existing USB drivers, giving you plug-and-play capability across Windows, Mac and Linux operating systems.



A 4K resolution variant of this model is available. The SDI input supports up to 6G-SDI signals instead of the standard 2K-SDI. The Capture SDI 4K Plus also supports 4K resolution inputs and output streams – an upgrade from the Capture SDI Plus’ 2K limit.
