Overview

The Blackmagic Design DeckLink Quad HDMI Recorder addresses a real gap in the streaming hardware market: the need to capture multiple high-quality HDMI sources simultaneously without stacking USB capture devices or investing in a full broadcast switcher. Four HDMI 2.0b inputs on a single PCIe card means a multi-cam streaming setup — face cam, gameplay, secondary B-roll, and a scene source — can all feed into OBS as discrete capture devices from one slot. Supporting up to 4Kp30 per input at RGB 4:4:4 12-bit depth, the card captures more color and luminance information than any USB 3.0 device on the market, and viewers will notice the difference in skin tones and fine detail on face-cam shots.

Installation centers on Blackmagic's Desktop Video driver suite, which is mature and well-documented but does require a deliberate setup process — install drivers, run Desktop Video Setup to confirm each input is detected, then assign sources in OBS or vMix. Once configured, the card is rock-solid: the PCIe interface sidesteps the bandwidth contention and driver instability that plagues USB capture stacks during long streams. The card is built for desktop workstations with a full-length PCIe x8 or x16 slot, so it's not for compact builds, but for a dedicated streaming or production PC it consolidates four capture channels into a single, low-latency, professional-grade pipeline that holds up under broadcast conditions.

Key Features

Quad HDMI Connections: Equipped with four HDMI 2.0b connections allowing for simultaneous capture of multiple HDMI sources (8, 10, 12-bit RGB 4:4:4 in all modes up to 4Kp30 DCI and 8, 10-bit YUV 4:2:2 in all modes

PCIe Interface: Utilizes a high-speed PCIe interface for reliable data transfer and low-latency performance. PCI Express 8 lane generation 3 required, compatible with 8 and 16 lane PCI Express slots on Mac OS, Windows and Linux.

Wide Format Support: Compatible with a range of SD, HD, and 4K video standards. Supports Deep Color and HDR. Supports Rec. 601, Rec. 709, Rec. 2020 color spaces. Supports 8 channels of embedded 24-bit 48 kHz audio.

Software Compatibility: Works seamlessly with Blackmagic Design’s Media Express software, as well as other major applications such as Wirecast, vMix, OBS, and more.

Copy Protection: HDMI inputs are unable to capture from copy protected HDMI sources.

Pros & Cons

👍 Pros

  • Four independent HDMI 2.0b inputs let you run a full multi-cam setup — face cam, game capture, secondary angle, and a title card source — all from a single PCIe slot without a USB hub or multiple cards.
  • PCIe Gen 3 x8 interface eliminates the USB bandwidth bottleneck that causes frame drops on cheaper capture devices during sustained 4K capture sessions.
  • Supports 10-bit and 12-bit color depth with full RGB 4:4:4 chroma sampling, which means your face cam footage retains noticeably more color detail in VODs compared to 4:2:0 USB capture cards.
  • Native compatibility with OBS, vMix, and Wirecast means no proprietary capture app required — it slots into your existing streaming stack cleanly.
  • Each HDMI input handles HDR and Deep Color, so high-contrast sources like OLED monitors and HDR cameras are represented accurately in your capture pipeline.

👎 Cons

  • Requires a PCIe x8 Gen 3 slot — small form factor and mini-ITX streaming builds typically lack the slot, making this a full-size desktop-only solution.
  • Blackmagic Desktop Video driver updates occasionally lag behind major OS releases, which can cause the card to disappear from OBS until a driver update is released.
  • No audio mixing or on-board processing — you're capturing raw HDMI audio embedded in each stream, so complex multi-source audio routing still needs to happen in OBS or an external mixer.
  • At this price tier, the card is overkill for single-source streamers — the four-input capability only justifies the cost if you're running a multi-cam or multi-source production setup.

Frequently Asked Questions

Yes — OBS and Streamlabs both recognize the DeckLink Quad HDMI as a capture device via Blackmagic's desktop video driver. You'll need to install the Blackmagic Desktop Video driver and Desktop Video Setup utility first, then each of the four HDMI inputs appears as a separate capture source in OBS, letting you assign individual inputs to different scenes.
The PCIe Gen 3 x8 interface keeps capture latency extremely low — well under a frame at typical streaming resolutions. This card is designed for broadcast-grade live switching, so latency introduced by the card itself is negligible. Your stream delay will be dominated by encoder settings and platform buffering, not the capture card.
All four inputs support up to 4Kp30 DCI simultaneously at 8, 10, or 12-bit RGB 4:4:4. If you need 4Kp60, you'll be limited by the per-input bandwidth — check Blackmagic's format matrix for the specific resolution/frame rate combinations available across all four channels concurrently.
Yes — Blackmagic publishes Desktop Video drivers for all three platforms. The card requires a PCIe x8 Gen 3 slot (compatible with x16 physical slots), so it works in any desktop with an available full-size PCIe slot running macOS, Windows, or Linux.
No — like all capture cards, the DeckLink Quad HDMI cannot capture from HDCP-protected HDMI sources. Standard game console output in streaming/capture mode (non-protected), cameras, and video switchers all work fine.
