Magewell USB Capture SDI Plus captures SD /HD /3G-A /3G-B/2K SDI signals from a wide range of devices including high definition cameras (professional /surveillance /video conference), video switchers and so on. The maximum input resolution and frame rate is 2048×1080. The USB Capture SDI Plus can deliver the captured video to a computer at up to 2048×1080.

The USB Capture SDI Plus has an SDI input interface as well as a an SDI loop through interface, which allows for monitoring the image while streaming and/or recording. This loop-through feature is not available on the original USB SDI dongle. Additionally, the new USB Capture SDI Plus has new audio input and output functions. A 3.5mm audio interface allows for capture of analog audio from a separate audio device (not embedded in the SDI input). This eliminates the need for an additional audio capture device. The 3.5mm headphones interface allows for playback of audio (either extracted from the embedded SDI audio or from the analog audio input).

The USB capture devices can be used in a number of industries, including sporting and live events broadcasting and recording, video conferencing, medical imaging, and surveillance. You can use it to capture a video output device or the desktop of the streaming computer.
