Product Description
The Magewell USB Capture SDI 4K Pro is the highest-specification SDI capture device in the USB Capture family. It handles 12G-SDI signals — the broadcast standard for 4K SDI — and captures them at full 4K60 resolution via USB 3.2 Gen 2x2 (20Gbps). If you're working in a professional broadcast or live production environment with 4K SDI infrastructure, this is the device that bridges it to your editing or streaming workflow without compromise.
12G-SDI carries a single 4K signal over a single BNC cable at up to 12Gbps — the same connector and cable infrastructure you already have, just at four times the bandwidth of 3G-SDI. The SDI 4K Pro handles the full range from SD-SDI through to 12G-SDI, so it works across your entire fleet of SDI equipment regardless of vintage. The BNC loop-through keeps the signal flowing to downstream broadcast monitors and recorders simultaneously.
With ~700 Mpixels/s FPGA processing and up to 10-bit colour capture, the SDI 4K Pro is purpose-built for broadcast quality at the highest resolutions. Same plug-and-play driver-free operation. Same broad software compatibility. Same operating temperature range extended to 60°C for rack and production environments.

Product Q&A
Q: What is the difference between the SDI Plus and the SDI 4K Pro?
A: The SDI Plus handles up to 3G-SDI (2048x1080 max) and uses USB 3.0. The SDI 4K Pro handles up to 12G-SDI (4096x2160 at 60fps) and uses USB 3.2 Gen 2x2 for sufficient bandwidth to capture 4K60. If your cameras and switchers output 4K SDI signals, you need the SDI 4K Pro. For HD SDI workflows (1080p and below), the SDI Plus is sufficient.
Q: Does my computer need a specific USB port for this?
A: For maximum 4K60 capture performance, you need a USB 3.2 Gen 2x2 or Thunderbolt 3/4 port. On current Mac hardware, all Thunderbolt ports meet this requirement. The device will still function at lower resolutions/frame rates on USB 3.0 ports.
Q: Does it work with Mac?
A: Yes. Fully compatible with macOS 10.12 and above on both Apple Silicon and Intel Macs. No drivers required — recognised natively via AVCaptureSession.
Q: Can I use this in a rack-mounted production environment?
A: Yes. The SDI 4K Pro is rated to operate up to 60°C — higher than the standard 45°C limit of the Plus models — making it suitable for enclosed rack environments where temperatures are elevated.
Q: What SDI standards does it support?
A: The SDI 4K Pro supports the full SDI signal hierarchy: SD-SDI, HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI. It is backwards compatible with all your existing SDI equipment.
