Product Description
The Magewell USB Capture SDI Plus is a single-channel HD external video capture device with a USB 3.0 host interface. It captures SD/HD/3G-SDI signals along with up to 8 channels of embedded audio, and provides a BNC loop-through output so the signal can simultaneously feed other equipment without a separate distribution amplifier. A 3.5mm interface accepts an external analog audio source for capture and can also output SDI embedded audio for monitoring. Maximum input and loop-through resolution reaches 2048x1080 60fps 4:2:2 10-bit; the capture path supports resolutions up to 2048x1080 and frame rates up to 120fps (actual frame rate may be limited by USB bandwidth and internal working frequency; enumerated 1080p and 720p output modes support up to 60fps), with approximately 160 Mpixels/s processing bandwidth. Built-in hardware video processing functions include de-interlacing, cropping, scaling, aspect-ratio conversion, color-space conversion, frame-rate conversion, flip and mirror. The device is plug-and-play with no driver installation required, and is compatible with Windows, Linux, macOS and Chrome OS, enabling direct use in Zoom Rooms, Microsoft Teams, OBS Studio, XSplit and other mainstream software. The bundled USB Capture Utility supports parameter configuration and firmware upgrade, while the MWCapture SDK is available for advanced system integration development.
