Our take on the Blackmagic DeckLink Duo 2
The Blackmagic DeckLink Duo 2 is a PCIe card with four SDI connections, built for streamers running a multi camera rig with SDI gear.
Each connection is 3G SDI, capturing or playing back video up to 1080p60, and all four can run at once. A reference input takes genlock signals so cameras stay in sync. The listing requires a four lane PCI Express Gen 2 slot, and 8 and 16 lane slots also work. Its tracked price is $579, unchanged across 9 points from Aug 25 to Oct 19, 2026, so there is no sale pattern to wait for. Retailers rate it 4.8 across 262 ratings.
- Four independent 3G SDI connections
- Genlock reference input
- Capture and playback at the same time
- SDI only, so HDMI cameras need a converter
- Tops out at 1080p60
