Blackmagic Design Duo 2 Reviews

Works well

Wanted to capture 3 cameras at 60 FPS. Unlike every USB solution that we tried, this worked in a Thunderbolt enclosure perfectly.

Problem Solved!

Our Mac Studio kept getting confused on what picture to output on each of the built-in thunderbolt ports, and freezing video coming into another thunderbolt port. This keeps the outputs going to the correct displays, and so far video input has not frozen. Haven't used in live production yet, but fingers crossed, our livestream glitches are behind us.
