Blackmagic Design BM-BDLKDUO2LP DeckLink Duo 2 Mini Card

The Blackmagic Design DeckLink Duo 2 Mini is a low-profile PCIe capture and playback card designed for professional video workflows that require multiple independent SDI channels in a space-constrained system. It provides four mini 3G-SDI connectors, each of which can be independently assigned as a capture input or playback output. This flexibility allows configurations ranging from four simultaneous capture channels to four playback outputs, or any combination in between — making it adaptable to live production switching, multi-camera ingest, broadcast playout, and post-production review workflows.

All four SDI connections support SD and HD formats up to 1080p60 with embedded audio, keeping cabling simple by carrying both video and audio on each SDI link. The card includes built-in hardware conversion capabilities for SD/HD down-conversion, up-conversion, and cross-conversion, which means you can work with mixed-format sources without adding external conversion boxes to your signal chain. Compatible with macOS, Windows, and Linux, it integrates with Blackmagic's DaVinci Resolve and a broad ecosystem of third-party editing, streaming, and broadcast software. The low-profile PCIe form factor fits standard workstations and compact rack-mount servers, and multiple cards can be installed in a single system to scale channel count as production demands grow.
