Professional 3G-SDI capture in a pocket-sized dongle.
The Magewell USB Capture SDI Gen 2 captures broadcast-grade SDI video with a dedicated loop-through output for local monitoring. Built for live events and field production, it connects any SD/HD/3G-SDI source to your computer via USB 3.0 with no drivers required.
The FPGA-based onboard processing handles all signal conversion in hardware — your CPU is free to run your production software. The SDI loop-through output lets you continue monitoring on-site while simultaneously capturing to your computer.
