Four independent HDMI capture channels — the high-density ingest 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 Quad HDMI compresses four fully independent HDMI capture engines onto a single full-height PCIe x4 card. For density per slot it is unrivalled — four broadcast-grade HDMI ingests in the space one card occupies.
In live production this is the card behind multi-camera streaming workflows: four HDMI cameras feed directly into vMix or Wirecast for live switching, with each channel running independently in hardware. Common deployments include school esports facilities, multi-camera houses of worship, and small studios where a single production PC handles all four cameras.
Because each channel has its own FPGA processing path, the card handles mixed-format input without compromise — one 1080p60 PTZ alongside three 720p webcams works exactly the same as four matching cameras would. Rated for continuous 24/7 operation, so installation in a permanent live-production rack is straightforward.

The Pro Capture Quad HDMI uses a Full-height 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 Quad 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 Quad 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 Quad HDMI accepts 4x independent HDMI channels.
The Pro Capture Quad HDMI captures at up to 1920x1080 @ 60fps per channel.
