Description
Magewell Pro Capture Dual SDI 4K Plus
The Magewell Pro Capture Dual SDI 4K Plus is a professional dual-channel PCIe capture card designed for high-end 4K SDI workflows. With two independent SDI input channels supporting 3G/6G/12G SDI configurations (depending on signal structure), this card delivers exceptional clarity, ultra-low-latency performance, and advanced on-board image processing—perfect for broadcast, medical imaging, live production, surveillance, and multi-camera 4K workflows.
Dual Independent 4K SDI Capture
This card features two independent SDI inputs, each capable of capturing up to 4096×2160 depending on SDI link type. Whether you use single-link 12G, dual-link 6G, or quad-link 3G SDI, the Pro Capture Dual SDI 4K Plus adapts seamlessly to your workflow. Ideal for capturing multiple 4K cameras, studio switchers, or broadcast infrastructure simultaneously.
Advanced On-Board Image Processing
Magewell’s hardware processing engine performs scaling, cropping, de-interlacing, color-space conversion, and frame-rate optimization directly on the card. This dramatically reduces CPU workload while ensuring smooth, stable operation across both channels—even during long 4K production sessions.
Ultra-Low Latency & PCIe High-Bandwidth Architecture
The PCIe high-speed interface ensures reliable throughput for simultaneous 4K capture. Combined with ultra-low latency performance, the card is ideal for real-time workflows such as broadcast mixing, IMAG, medical visualization, sports analysis, and multi-source live streaming.
Cross-Platform Compatibility
Compatible with Windows, macOS, and Linux, the card integrates seamlessly with OBS Studio, vMix, Wirecast, Zoom, Teams, VLC, and leading NLE/imaging platforms. It also supports multi-card installations for large, multi-channel systems.
