Overview

The Blackmagic Design DeckLink Duo 2 is a PCI Express capture and playback card built for professional environments that demand multi-channel SDI I/O in a single, space-efficient solution. With four independent SDI connections, each individually configurable as an input or output, the card is engineered for media playout systems, multi-screen digital signage installations, and real-time multi-channel ingest workflows. Supporting SDI formats from standard definition through full HD at 1080p60, it handles the resolution requirements of most broadcast and institutional video operations.

Cross-platform compatibility with Mac, Windows, and Linux ensures the DeckLink Duo 2 integrates into virtually any production or IT environment, and it works with Blackmagic's free Media Express software as well as popular third-party applications. The ability to run four channels independently from one card slot is particularly valuable in servers and systems where PCIe slots are at a premium, consolidating what would otherwise require multiple cards into a single installation. For facilities operating in HD or managing legacy SD content alongside HD material, the DeckLink Duo 2 provides a dependable and cost-effective multi-channel solution.

Key Features

Four Independent 3G-SDI Connections: Simultaneously capture and playback up to four video streams at resolutions up to 1080p60.

PCIe Interface: Utilizes a high-speed PCIe interface for reliable data transfer and low-latency performance. PCI Express 4 lane generation 2 required, compatible with 4, 8 and 16 lane PCI Express slots.

Wide Format Support: Compatible with a range of SD, HD, and 3G-SDI formats, including 720p, 1080i, and 1080p.

Software Compatibility: Works seamlessly with a range of editing, visual effects, and streaming software applications.

Reference Input: Features a reference input for synchronizing with external genlock (blackburst and try-sync) signals, ensuring precise timing in multi-camera setups.
