What is the Magewell USB Capture SDI Plus capture device?
The Magewell USB Capture SDI Plus is a driver-free USB 3.0 capture device that brings one SD, HD or 3G-SDI signal into a computer as a webcam while passing the SDI signal on through a loop-through. It captures up to 2048×1080, adds an analog line input and line output, and works with Zoom Rooms, Microsoft Teams, OBS and other UVC software. It suits rooms where an SDI camera feeds both a local monitor or switcher and a conferencing or streaming PC.
How does the Magewell USB Capture SDI Plus work?
The device accepts SD, HD and 3G-SDI on a BNC input, receiving 3G-SDI over cable runs up to 150 m, and passes the signal unchanged to the BNC loop-through. Its onboard pipeline crops, scales, deinterlaces and converts color format and frame rate before sending up to 2048×1080 at up to 120 fps to the computer over USB 3.0. Audio can come from the SDI signal or the 3.5 mm line input, and the SDI audio can be monitored on the line output.
The computer sees it as a UVC and UAC device, so no drivers are needed. The USB Capture Utility sets capture options and updates firmware, and the MWCapture SDK supports custom applications. It is bus-powered at about 2.5 W and rated for 24/7 operation.
