DUO 2 HD 4-Line 12BIT SDI


Blackmagic Design Duo 2 Overview

The Blackmagic Design DeckLink Duo 2 is a versatile video I/O card for professional video workflows, with four bi-directional SDI interfaces. Because each SDI interface can be configured to be either an input or an output, a computer with this card installed can be used as a media play-out system, a multi-screen digital signage server, a live keyer, a real-time multi-channel capture system, or a combination of the above depending on your current workflow. There is also a reference input for syncing with other studio equipment.


  • Real-time hardware-based color space conversion
  • HD down conversion: On output, a built-in, high-quality software down converter from HD to SD. SD downconversion styles include letterbox, anamorphic 16:9, and center cut 4:3.
  • HD upconversion: On-board, high-quality software converts SD to 720 or 1080 HD. There are three options: 4:3 pillar box, 14:9 zoom, and 16:9 zoom.
  • Cross conversion: On playback, built-in, high-quality hardware cross conversion from 720 to 1080 HD and 1080 to 720.
  • Final Cut Pro X internal effects, Premiere Pro CC Mercury Playback Engine effects, and Avid Media Composer internal effects are all supported in real-time.
