The Magewell USB Capture SDI Plus is a one-channel 2K capture device that interfaces with your computer via USB 3.0. It features loop-through BNC input/output that allows you to see your video on a downstream device, while you are capturing it into your computer. It also has a line-in audio input, for capturing audio directly, without picture, or you can de-embed the audio from the SDI stream.
