Magewell USB Capture SDI 4K Plus (32100)


Available on backorder

SKU: MAGEWELL-32100 Category: Brand:


The Magewell USB Capture SDI 4K Plus connects to your computer over a USB interface and lets you capture up to a 4K DCI resolution signal (4096 x 2160) with embedded audio via a 6G-SDI input. It also features a 6G-SDI loop-through for local monitoring, and 3.5mm audio input and output for capturing external audio and extracting embedded audio. It’s compatible with Windows, Mac, Linux, and Chrome operating systems.

The card offers a variety of processing and other features, including resolution scaling and deinterlacing. It’s capable of operating 24 hours a day, 7 days a week while displaying the status of the input via an LED indicator (idle, input signal locked, memory failed, or FPGA configuration).


Please use the included Magewell USB 3.0 cable, which is a custom accessory. Using any other similar cable might cause capture problems and even damage the capture device.
