About this product
The Pro Capture Dual SDI is the two-channel sister to the single SDI card — two fully independent 3G/HD/SD-SDI capture engines with their own loop-throughs, in a single low-profile PCIe x4 footprint. Each channel runs entirely independently in hardware.
The most common deployment we see is dual-camera live production where the production PC needs to handle both cameras without dedicating two slots. In compliance workflows it allows a single card to capture programme output plus a backup feed (or a clean and dirty mix simultaneously). Both loop-throughs are active SDI, so the downstream chain continues without interruption even while capture is running.
Because each channel has its own FPGA, mixed-resolution input is supported — useful when an OB truck has cameras at different formats during a multi-venue production.

Frequently Asked Questions
The Pro Capture Dual SDI 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 SDI 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 SDI 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 SDI accepts 2x 3G/HD/SD-SDI with loop-through.
The Pro Capture Dual SDI 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.
