Magewell Pro Capture Dual HDMI 4K Plus LT

Two Independent HDMI 4K60 Channels on One PCIe Card

The Magewell Pro Capture Dual HDMI 4K Plus LT provides two fully independent HDMI 4K capture channels on a single PCIe x8 card. Each channel captures at up to 3840x2160 at 60 frames per second, each runs its own dedicated FPGA processing pipeline, and each includes its own HDMI loop-through output. At £1,388, it is the professional solution for broadcast production environments that need simultaneous 4K60 ingest from two separate HDMI sources without occupying two separate PCIe slots.

What It Captures

Each of the two channels independently captures HDMI sources up to 3840x2160 at 60fps. The channels operate entirely independently: different sources, different resolutions, different frame rates if required. Each channel performs its own FPGA-based colour conversion, deinterlacing, and scaling without any processing shared with the second channel. Both channels present as independent capture devices to the host operating system and production software.

Loop-Through on Both Channels

Each channel has its own HDMI loop-through output. This means each source can simultaneously feed a monitoring display or downstream device directly from the card, without an external HDMI splitter on either channel. In a dual-source production environment, this removes two splitters from the signal chain and gives you a clean, unprocessed pass-through on both channels from a single card. The bracket carries two HDMI inputs and two corresponding HDMI loop-through outputs.

Who This Card Is For

• Broadcast production teams running multi-camera or multi-source 4K HDMI ingest from a single server
• Live event engineers capturing presentation feeds and camera output simultaneously via HDMI at 4K60
• Post-production facilities ingesting from two 4K HDMI sources in parallel for multicam or dual-stream workflows
• AV integrators building high-density 4K ingest servers where PCIe slot count is limited and two channels from one card is operationally efficient

Dual Independent FPGA Architecture

The two channels do not share processing resources. Each has its own FPGA. Running two simultaneous 4K60 streams places significant processing demand on any shared silicon, and a shared-core dual-channel card will typically limit total throughput or introduce contention under load. The dual FPGA design on the Pro Capture Dual HDMI 4K Plus LT ensures both channels operate at full capability simultaneously, with no performance compromise on either channel caused by the other being active.

How It Compares to Two Separate Cards

Two Pro Capture HDMI 4K Plus cards (at £693 each) would deliver the same channel count at £1,386: essentially the same total cost as this card, but using two PCIe x4 slots instead of one PCIe x8 slot. Where PCIe slot count matters more than slot size, the dual card is the more efficient choice. Where the reverse is true, two single cards remain an option.

Software Compatibility

Compatible with vMix, Wirecast, OBS Studio, Adobe Premiere Pro, and FFmpeg. Supported on Windows 10, Windows 11, and Windows Server; Linux kernel 3.x and above; and macOS 10.14 and later. Both channels appear as independent capture devices.
