Magewell Pro Capture HDMI 4K

4K HDMI Capture on a Single Low-Profile PCIe Card

The Magewell Pro Capture HDMI 4K brings single-channel HDMI capture up to 3840x2160 at 30 frames per second, with full 1080p60 support, on a low-profile PCIe x4 card. Priced at £385, it is the logical upgrade from Magewell's standard Pro Capture HDMI when your sources have moved to 4K. If you are capturing from 4K cameras, 4K presentation systems, or 4K-output devices and need that resolution reflected faithfully in your production pipeline, this is the card to consider before stepping up to the 4K Plus range.

What It Captures

The Pro Capture HDMI 4K accepts HDMI signals up to 3840x2160 at 30fps (4K30), and handles all standard resolutions below that at higher frame rates, including 1080p60. FPGA hardware on the card manages scaling, deinterlacing, and colour space conversion, so the signal arriving at your production software is clean and correctly formatted. The card auto-detects incoming HDMI signal formats without manual intervention when sources change.

Who This Card Is For

The Pro Capture HDMI 4K suits producers who need 4K capture capability but are not yet working with 4K60 sources:

• Live event producers capturing from 4K cameras or PTZ units outputting HDMI at 4K30
• Corporate AV teams recording 4K presentations from laptops or display processors
• Post-production facilities ingesting from 4K playback decks or cameras via HDMI
• Streaming operators who need to capture 4K for downstream scaling and delivery
• Organisations future-proofing their ingest infrastructure ahead of a full 4K transition

FPGA Processing on the Card

The FPGA on the Pro Capture HDMI 4K handles the heavier lifting of 4K signal processing without placing that load on the host CPU. Colour space conversion, deinterlacing, and scaling are performed in dedicated hardware. This matters at 4K resolutions where software-side processing of raw captured data would create significant CPU overhead in parallel production workflows.

How It Compares to the Pro Capture HDMI 4K Plus

The Pro Capture HDMI 4K Plus, priced at £693, supports 4K at 60fps, adds an HDMI loop-through output for simultaneous monitoring without a splitter, and includes HDR and HLG support. It is the right card if your sources run at 4K60 or if you need to feed the same signal to a monitoring display while capturing. The Pro Capture HDMI 4K at £385 covers 4K30 and 1080p60 at a significantly lower price point for teams whose current sources do not require 4K60 throughput and have no need for a card-level monitor feed.

Software Compatibility

Compatible with vMix, Wirecast, OBS Studio, Adobe Premiere Pro, and FFmpeg. The card operates under Windows 10, Windows 11, and Windows Server; Linux kernel 3.x and above; and macOS 10.14 and later. Magewell's driver package exposes a standard capture device interface across all supported platforms.
