Magewell Pro Capture HDMI 4K Plus

4K60 HDMI Capture with Loop-Through and HDR Support

The Magewell Pro Capture HDMI 4K Plus is the flagship single-channel HDMI PCIe capture card in Magewell's professional range. It captures HDMI signals up to 3840x2160 at 60 frames per second, includes a built-in HDMI loop-through output so you can simultaneously feed a monitor from the same source without a splitter, and adds full HDR and HLG support for high dynamic range workflows. At £693, it is the complete answer for professional single-channel HDMI 4K ingest where frame rate, monitoring capability, and colour fidelity are all requirements.

What It Captures

The Pro Capture HDMI 4K Plus accepts HDMI signals up to 3840x2160 at 60fps, covering all standard resolutions below 4K at their native frame rates. FPGA processing handles colour conversion, deinterlacing, and scaling on the card, keeping host CPU load minimal. HDR and HLG formats are supported, making this card appropriate for production workflows that are moving into or already operating in high dynamic range.

The Loop-Through Output

The HDMI loop-through output is a practical feature that matters considerably in real-world production environments. Without loop-through, feeding a source signal to both a capture card and a monitor requires an HDMI splitter: additional hardware, an additional potential point of failure, and often added latency on one or both outputs. The Pro Capture HDMI 4K Plus routes the source signal directly through to an HDMI output on the card bracket, with no splitter needed. The monitor sees a clean, unprocessed signal. Your capture sees the same. This is particularly useful in tight rack deployments, presentation capture rigs, and broadcast environments where signal chain simplicity is operationally important.

Who This Card Is For

• Live broadcast and production operators capturing 4K60 HDMI sources including cameras, display computers, and signal processors
• Engineers who need to monitor a source simultaneously while capturing it, without adding a splitter to the signal chain
• Post-production and archiving operations working with HDR or HLG content via HDMI
• Facilities future-proofing single-channel HDMI ingest infrastructure at the highest current standard

How It Compares to the Rest of the HDMI 4K Range

The Pro Capture HDMI 4K (£385) captures 4K30, has no loop-through, and does not support HDR. It is the right card when your source is 4K30 and a monitor feed from the card is not needed. The Pro Capture HDMI 4K Plus LT (£693) captures 4K60 and supports HDR but removes the loop-through output for buyers whose monitoring is handled separately. The Pro Capture HDMI 4K Plus retains the loop-through and is the complete package when all three capabilities are required: 4K60, HDR, and simultaneous monitoring from the card.

Software Compatibility

Fully compatible with vMix, Wirecast, OBS Studio, Adobe Premiere Pro, and FFmpeg. Supports Windows 10, Windows 11, and Windows Server; Linux kernel 3.x and above; and macOS 10.14 and later. Magewell's drivers expose a standard capture device interface across all supported platforms.
