About this product
The Pro Capture SDI 4K Plus captures 4K60 over 12G-SDI single-link — the format that current professional broadcast cameras output natively. With active loop-through, low-profile form factor, and broadcast-grade FPGA processing, it is the SDI counterpart to the HDMI 4K Plus LT.
In broadcast and OB-truck workflows this card is becoming the standard 4K ingest specification. The single-link 12G-SDI input is simpler to cable than older quad-link 3G-SDI 4K (one cable instead of four), and the active loop-through means the captured signal continues feeding downstream broadcast equipment without interruption.
Backward compatibility with 6G, 3G, HD and SD-SDI is built in — the card adapts to whatever signal a camera delivers without configuration. Useful in mixed-vintage facilities where the same chassis may capture from a 4K cinema camera one day and an HD studio camera the next.

Frequently Asked Questions
The Pro Capture SDI 4K Plus 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 SDI 4K Plus 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 SDI 4K Plus 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 SDI 4K Plus accepts 12G-SDI with loop-through.
The Pro Capture SDI 4K Plus captures at up to 3840x2160 @ 60fps.
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.
