Magewell Pro Capture Dual HDMI review

The Magewell Pro Capture Dual HDMI is a two-channel, internal PCIe card for a Windows/Linux/Mac production computer that needs separate HDMI capture sources. Its defining difference from the one-channel Pro Capture HDMI is not a higher gaming passthrough ceiling: it is a second input channel. The manufacturer identifies part 11080 and SKU 110800000, with two HDMI inputs and embedded audio.

Two inputs are not two outputs

The dual card has two HDMI Type A inputs, each described for HDMI 1.4a and DVI 1.0 source compatibility. Magewell specifies input and capture raster support up to 2048 by 2160 pixels. The board's capture-rate ceiling is listed as up to 144 fps in selected modes, but the technical page warns that PCIe bandwidth and onboard pixel clock limit actual rates; its 1920 by 1080 example is about 80 fps. In the source evidence reviewed here, 1080p60 is the conservative Windows/OBS target. The figures do not support interpreting the card as a 4K capture model, a 1080p120 card, or a guarantee of every input sustaining the peak mode simultaneously.

That distinction matters when choosing a multi-channel card. The product is designed to expose two separate channels, but actual recording depends on source formats, per-channel settings, software, host bandwidth and the work the computer performs after capture. Magewell lists multiple capture streams and two video-processing pipelines, yet does not convert the marketing channel count into a universal promise for every combination of frame rate, color format and concurrent streams. If the job requires two feeds at a particular rate, check that exact arrangement against current driver documentation and the host configuration.

PCIe x4 changes the installation decision

This is a low-profile PCIe Gen2 x4 card measuring about 115.99 by 68.88 mm without its bracket. Magewell lists both high-performance and low-power firmware modes, with maximum power figures of approximately 9.09 W and 8.13 W respectively. Those figures are useful when planning a compact system, but they are not a substitute for checking the motherboard slot, lane sharing, chassis clearance, cooling, firmware revision and driver support. A board's slot may be physically x16 while sharing lanes; verify the system manual rather than relying on the connector length alone.

Magewell's product page lists Windows, Linux and Mac, Capture Express and a broad set of compatible software; the technical sheet specifically names OBS and Windows/Linux/Mac APIs. For a Mac, the reviewed evidence does not supply a Mac-specific mode table, so a Mac OS match here is a broad compatibility reference, not a 1080p60 guarantee. Check the current driver and any PCIe enclosure/expansion chassis before designing around that route.

Capture-only HDMI has a clear tradeoff

The card's two HDMI sockets are inputs, not an input/output pair. Magewell does not list a built-in display output or loop-through function. If a source must continue to a display, plan a separate output path and confirm signal format and copy-protection handling. The manufacturer's troubleshooting guidance says HDCP-encrypted HDMI sources are not capturable. That rules out treating this as a device for recording protected program material.

Each HDMI input can carry embedded audio, and Magewell describes audio streams through its SDK. An OBS setup still needs the correct video/audio device selection for each source, and the computer must cope with both feeds and the encoder workload. A card can expose two channels without making the application configuration automatic. Do not count the input ports as separate monitor outputs or assume that adding a splitter solves source-protection restrictions.

How to choose among the channel counts

For a single source or an analog component/composite/S-video archive, the one-channel Pro Capture HDMI has a DB9 breakout and x1 link. For two HDMI sources, this Dual model is the more direct physical fit. If the production plan truly needs four inputs, compare the Quad HDMI, while checking its normal-profile dimensions and combined workload. None of these three is a 4K capture or display-passthrough choice.

The Dual HDMI makes sense when two independently addressable capture inputs matter more than portability, modern console passthrough or a high-resolution capture headline. It is an internal card, so there is no USB portability benefit; the host needs a PCIe x4 connection and the source must be unencrypted. Before ordering, confirm the full model name and MFR 11080, inspect the specific bundle for any cables you need, and verify the number of feeds and mode combination your software must run. The public model match is a useful filter, not proof that a particular motherboard or production configuration has been tested.
