Description
Magewell Pro Capture Quad SDI
The Magewell Pro Capture Quad SDI is a professional, four-channel PCIe capture card engineered for high-end broadcast, live production, medical imaging, surveillance, and multi-camera workflows. With four independent 3G-SDI inputs, this card delivers unmatched flexibility, ultra-low latency, and rock-solid performance for demanding multi-source environments.
Four Independent SDI Inputs
Equipped with 4× 3G-SDI inputs, each channel operates independently—supporting different formats, resolutions, and frame rates simultaneously. This makes the Pro Capture Quad SDI the perfect solution for multi-camera streaming setups, vision mixing, recording, and monitoring applications.
Broadcast-Quality 3G-SDI Capture
Each input supports up to 1080p60, ensuring sharp, detailed, and reliable image capture. Ideal for professional cameras, switchers, routers, and broadcast signal chains where quality and stability are essential.
Advanced On-Board Processing
Magewell’s powerful hardware engine performs scaling, cropping, color conversion, de-interlacing, and frame-rate conversion directly on the card—minimizing CPU usage and ensuring smooth multi-channel performance even in 24/7 environments.
Ultra-Low Latency & High-Bandwidth PCIe Architecture
Designed for real-time operation, the Pro Capture Quad SDI offers ultra-low latency across all channels. The PCIe x4 interface provides high-speed throughput required for reliable four-channel HD capture.
Extensive Compatibility
Compatible with Windows, macOS, and Linux, and works seamlessly with major production platforms such as OBS Studio, vMix, Wirecast, Zoom, Teams, VLC, and most NLE software.
