The Magewell Pro Capture Dual SDI 4K Plus is a High-performance, low-latency PCIe capture card. This Two-channel 4K PCI card captures two 12G-SDI signals in either a Single-link 12G-SDI, Dual-link 6G-SDI, or Quad-link 3G-SDI connecting method. The Magewell Pro Capture SDI 4K Plus supports input resolution up to 4096×2160 pixels.

These models automatically detect the input signal format, delivering reliable, high-quality video and audio capture for video professionals, systems integrators, and OEM developers. Moreover, All Pro Capture models feature Magewell’s FPGA-based, zero-CPU-usage video processing, providing high-quality up/down conversion and image adjustments without consuming valuable host system processing power.

Pro Capture devices support Windows, Linux and macOS operating systems – including x86, x64 & ARM architectures – and offer extensive compatibility with popular streaming, live production, web conferencing, lecture capture, collaboration, and medical imaging software. The Magewell MWCapture SDK provides both generic interfaces and custom APIs across OS platforms, helping developers leverage the full capabilities of Magewell capture hardware and achieve lower-latency, multi-stream capture and AV synchronization across multi-channel or even multiple capture cards.

Capture two 12G-SDI signals in one of the following connecting methods: 
- Single-link 12G-SDI 
- Dual-link 6G-SDI 
- Quad-link 3G-SDI
