Professional capture card for 4K workflows
The Blackmagic Design DeckLink 4K Extreme 12G is a PCI Express 8-lane generation 2 card built for broadcast and post-production. It targets editors and engineers who need simultaneous capture and playback of UHD and DCI 4K up to 60 fps. The board fits 8- and 16-lane slots and includes an HDMI mezzanine option for flexible I/O.
Dual 12G-SDI and analog connections
Two 12G-SDI inputs and outputs handle single-link and dual-link 4:2:2 or 4:4:4 signals with 2D/3D switching. Analog component, composite, S-Video and XLR audio ports sit on the rear bracket for legacy deck integration. The 6.69-inch depth suits standard workstation chassis without blocking adjacent slots.
PCIe Gen2 bandwidth limits 4K60 12-bit
The 8-lane generation 2 interface caps sustained throughput, so uncompressed 12-bit 4:4:4 at 4K60 may require frame buffering or compressed codecs such as ProRes 4444. Systems must run macOS 10.8 or later, Windows 7 64-bit or later, or Linux with supported NLE software. Buyers needing higher bandwidth or newer OS certifications should verify platform roadmap before purchase.

| Feature | Flexible Format Support The card offers flexible format and system support, letting you work with compressed video formats such as ProRes and DNxHD, as well as 12-bit 4:4:4 uncompressed video. When working with uncompressed video, all images are pixel-for-pixel identical to the source, without any generational loss. This lets you get sharper keying with green screens, cleaner compositions, superior color correction, and more. Support for common file formats provides ready-to-edit files for use in popular editing, effects, and design software applications. DeckLink Studio 4K is compat |

Questions about this item
What does the PCI Express 8-lane Gen 2 interface cap in practice?
It provides up to 4 GB/s throughput, limiting 12G-SDI capture and playback to the card's supported 4K 60 fps 4:4:4 formats.
What slot and chassis space does the card need to fit?
It requires an 8-lane or 16-lane PCIe slot and 17 cm depth, plus room for the included HDMI mezzanine card.
How is the HDMI mezzanine card installed, and what step is often missed?
Attach the mezzanine card to the main board header before inserting the assembly into the PCIe slot; skipping this leaves HDMI I/O inactive.
