Magewell Pro Capture DVI

Magewell Pro Capture DVI: Single-Channel DVI Capture for Legacy and Specialist Sources

The Magewell Pro Capture DVI captures a single DVI source and delivers it to your recording or production software as a standard capture device. At £246, it sits slightly above the HDMI equivalent in price, reflecting the specialist nature of the connector. DVI is not obsolete. It is the active output standard on medical imaging equipment, industrial control systems, legacy digital signage hardware, KVM extenders, and a large installed base of commercial equipment that has no straightforward path to HDMI without active signal conversion.

What This Card Accepts

The Pro Capture DVI handles both DVI-D (digital-only) and DVI-I (digital and analogue combined) connectors. DVI-D covers standard single-link and dual-link digital signals from computers, graphics cards, and digital signage controllers. DVI-I adds the analogue component carried in the wider DVI-I connector, which older hardware and some industrial equipment still outputs. Maximum input resolution is 2048x2160, covering the full range of computer-generated DVI output from standard desktop resolution up to 2K digital signage and presentation content.

The card also includes an analogue header supporting CVBS composite, S-Video, and YPbPr component video with stereo analogue audio, providing additional legacy capture options from a single card without needing separate hardware.

Real-World Use Cases for DVI Capture

The buyers for this card are not choosing DVI as a preference. They are buying it because the equipment they need to capture outputs DVI, and inserting an active converter into the signal chain adds latency, cost, and additional failure points. The Pro Capture DVI captures the native DVI signal directly, removing the need for any intermediate conversion. Typical deployments include:

• Medical and clinical environments where diagnostic imaging workstations, endoscopy systems, and monitoring displays use DVI outputs that require recording for clinical review, training, or compliance purposes
• Industrial automation and process control where SCADA systems, PLCs, and HMI panels output DVI signals that need to be captured remotely or archived
• Digital signage testing and content quality assurance, capturing the actual output of a signage player to verify content scheduling and display behaviour
• KVM over IP systems delivering DVI video to a remote capture PC for session recording and compliance monitoring
• Legacy broadcast and post-production equipment with DVI monitoring or confidence outputs that need to be integrated into modern workflows
• Training and documentation workflows where source hardware only has DVI output and conversion is not viable

FPGA Processing

The onboard FPGA handles scaling, deinterlacing, colour space conversion, and frame-rate conversion in hardware. The host CPU receives a clean, processed video stream rather than raw DVI data. In medical and industrial environments where the capture PC is also running analysis, monitoring, or automation software, this hardware offload is particularly important for maintaining CPU headroom.

Why Not Just Use a DVI-to-HDMI Adapter and an HDMI Card

A passive DVI-to-HDMI adapter works in a limited set of circumstances: when the DVI source is configured to output an HDMI-compatible signal and timing. Many industrial and medical DVI sources are not. Active converters resolve this but add latency, require power, and introduce an additional component into a signal chain that may be subject to qualification or validation requirements. In regulated environments, adding an unvalidated adapter is not straightforward. The Pro Capture DVI eliminates the adapter entirely, capturing the native DVI signal with known, validated Magewell hardware reliability.

Software and OS Support

The card works with vMix, Wirecast, OBS Studio, Adobe Premiere Pro, FFmpeg, and Magewell Capture Express. It uses a low-profile x1 PCIe slot and ships with full-height and low-profile brackets. Windows 10, 11, and Windows Server require the Magewell driver package. Linux 3.x and later uses V4L2 without an additional driver. macOS 10.14 and later uses the MWCapture SDK. The card is rated for 24/7 continuous operation, which is essential for medical, industrial, and monitoring deployments where the capture system runs permanently.
