DeckLink SDI 4K capture and playback card

This PCIe card adds a single 6G-SDI input and output to Mac, Windows or Linux workstations. It handles SD, HD, 2K and DCI 4K formats with 10-bit processing and up to 16 channels of embedded audio. Sony-compatible RS-422 deck control and reference input are built in.

Suits SDI-only workflows.

Broadcasters and post houses that rely exclusively on SDI cabling will appreciate the clean single-link 6G-SDI path. Facilities that require HDMI monitoring, analogue video routing or multi-channel capture beyond one input should consider other interfaces.

Single-link 6G-SDI at 4K 4:2:2

The card delivers UHD and DCI 4K at 4:2:2 colour sampling over a single 6G-SDI connection. It also supports 1080p 4:4:4 over 3G-SDI. This spec defines whether your 4K pipeline can stay on one cable.

Questions about this item

What is the maximum frame rate the DeckLink SDI 4K can sustain at 1080p before the 6G-SDI link becomes the bottleneck?

The card supports 1080p up to 60 fps over 6G-SDI 4:2:2, so the link itself is the ceiling at 60 frames per second.

How much heat or fan noise does the card add when it runs continuously in a workstation?

The DeckLink SDI 4K is a passive PCIe card with no onboard fan; it relies on case airflow and adds negligible acoustic noise.

Which slot type and operating system must the host computer already provide for the card to function?

A PCI Express x4 Gen 2 slot (compatible with x4, x8, x16) and Windows 7/8.1/10 64-bit, macOS 10.11 or later, or Linux are required.
