Two independent HDMI capture channels on a single low-profile PCIe x4 card.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The Pro Capture Dual HDMI gives a workstation two truly independent HDMI ingest channels on one low-profile PCIe x4 card. Each channel has its own FPGA processing pipeline, so the two streams can run at different resolutions, frame rates and colour formats without competing for bandwidth.
This is the card we recommend when the brief calls for two HDMI sources and a 1U rack server is in play — for example a small streaming venue capturing presenter laptop plus room camera, a corporate AV system handling two simultaneous huddle rooms, or a redundant capture build where the same source feeds two independent recording paths for compliance.
Because the channels are fully independent at the silicon level, mixing source types — one 1080p59.94 HDMI camera and one 1080i50 video conferencing feed, for instance — presents no issue. Both appear as separate capture devices in OBS, vMix and similar applications.

The Pro Capture Dual HDMI uses a Low-profile PCIe x4 slot. It will also fit in larger PCIe slots (x8, x16) as PCIe is backward compatible, but will run at the card's native lane width.
The Pro Capture Dual HDMI is a capture card. Simultaneous playback (loop-through) depends on the specific model — check the Loop-Through spec in the full specification table. ForeFront Imaging can advise if you need simultaneous I/O.
The Pro Capture Dual HDMI works with any software that supports DirectShow (Windows), V4L2 (Linux), or AVCaptureSession (macOS), including OBS Studio, vMix, Wirecast, Capture One, XSplit and most broadcast NLE software. Magewell's free Capture Express software is also available.
The Pro Capture Dual HDMI accepts 2x independent HDMI channels.
The Pro Capture Dual HDMI captures at up to 1920x1080 @ 60fps per channel.
Yes. Magewell Pro Capture cards are fully supported on Windows 10 and Windows 11. Driver downloads are available free from Magewell's website and from our Software page.
