Description

The Blackmagic Design DeckLink Quad 2 is an 8-lane PCIe card that features eight bidirectional, 12-bit SD/HD/3G-SDI DIN (Mini-BNC) connectors that are independently configurable to provide any combination of eight capture or playback channels at up to 1080p60. The card supports compressed video formats such as ProRes and DNxHD, as well as uncompressed 10-bit 4:2:2 and 4:4:4 video, making it ideal for use in both live broadcast and post-production. It is compatible with Mac, Windows, and Linux computers, and is supported by a wide range of software applications. For use with applications that don't capture video on their own, Blackmagic's Media Express software is included, allowing you to capture, organize, and manage your media. Read more

About the Blackmagic Design BMD-BDLKDVQD2 DeckLink Quad 2

The Blackmagic Design DeckLink Quad 2 is a high-density, professional PCI Express capture and playback card designed for the most demanding broadcast, live production, and post-production workflows. Its core capability is handling eight simultaneous channels of 3G-SDI or HD-SDI video in a single PCIe slot. Each channel is a full-duplex port, meaning all eight ports can be used for capture or playback independently or simultaneously, providing immense flexibility. This makes it an ideal solution for multi-camera live switching (e.g., connecting eight cameras directly to a vision mixer software like vMix or Wirecast), creating complex multi-monitor playback setups for broadcast graphics, or ingesting multiple video streams for editing or encoding.

A key feature of the Quad 2 is its support for 12G-SDI on all eight ports. This allows each connection to handle ultra-high-definition video formats, including 4Kp60 at 4:2:2, over a single BNC cable, drastically simplifying cabling for 4K workflows compared to older cards that required multiple cables (quad-link) for high frame rate 4K. The card also includes a dedicated Genlock input with support for tri-level sync, which is essential for frame-accurate synchronization in multi-channel broadcast environments. Additionally, it features an SDI Word Clock output to synchronize other SDI devices in the same system.

Targeted at professional video engineers, broadcast facilities, and large-scale production houses, the DeckLink Quad 2 is about maximizing I/O density and simplifying infrastructure. It is commonly used in conjunction with software like DaVinci Resolve (for multi-channel color grading or editing), live production software, and broadcast graphics systems. Its ability to replace multiple single or dual-channel cards with one unified solution reduces hardware complexity, saves PCIe slots, and provides a clean, synchronized signal path for complex video pipelines.

  • 8-Lane PCIe Interface
  • Resolutions up to 1080p60

FAQs about Blackmagic Design BMD-BDLKDVQD2 DeckLink Quad 2

What is the Blackmagic DeckLink Quad 2?

It is an 8-lane PCIe capture and playback card equipped with 8 independent, bidirectional 3G-SDI micro-BNC (DIN 1.0/2.3) connectors. It allows computers to ingest or output up to 8 distinct SDI video streams simultaneously on a single PCIe card.

What resolutions and frame rates does the DeckLink Quad 2 support?

It supports standard-definition and high-definition video formats up to 1080p60 over multi-rate 3G-SDI, HD-SDI, and SD-SDI. Note that it does not support 4K or Ultra HD resolutions, as it is limited to 3G-SDI data rates across its channels.

What does "bidirectional" mean for the 8 SDI channels?

Each of the 8 micro-BNC connections can be configured independently as either an input or an output using Blackmagic Desktop Video software or supported host applications. This flexibility allows configurations like 8 capture channels, 8 playback channels, or any split like 4 inputs and 4 outputs.

What type of PCIe slot is required?

It requires a physical PCIe x8 or x16 generation 2 (Gen 2) slot on the host computer's motherboard to ensure full bus bandwidth for 8 simultaneous 1080p60 feeds. It can also be installed in an external Thunderbolt-to-PCIe expansion chassis for use with laptops or compact workstations.

How is audio handled across the card?

The DeckLink Quad 2 supports up to 16 channels of embedded uncompressed 24-bit 48 kHz digital audio per SDI connection. This allows up to 128 total audio channels across all 8 video streams combined.

What type of cables are needed to connect standard BNC gear?

Because the card uses dense DIN 1.0/2.3 (micro-BNC) connectors on its rear bracket to fit 8 ports onto a single PCIe card, it requires DIN 1.0/2.3 to standard full-size female BNC adapter cables. Blackmagic typically provides an adapter cable kit with the card.

Does the card support reference/genlock synchronization?

Yes, it features a dedicated reference input (via a 9th micro-BNC connector) supporting Blackburst and Tri-Sync signals. This allows all playback outputs to be locked to a master house sync reference in broadcast facilities.

Which operating systems and broadcast software work with it?

It is fully compatible with Windows, macOS, and Linux, and integrates natively with production applications like vMix, OBS Studio, Wirecast, CasparCG, and ProPresenter. The channels appear as 8 individual capture and playback devices within the host software.
