Blackmagic Design UltraStudio 4K Mini – Thunderbolt 3 Capture & Playback

Product Overview

The Blackmagic Design UltraStudio 4K Mini is a Thunderbolt 3 4K capture and playback device for edit bays and live production rooms that need broadcast-grade SDI and HDMI I/O in a compact unit. It captures up to DCI 4K60 4:2:2 over single-link 12G-SDI and DCI 4K30 over HDMI, making it a practical DCI 4K60 12G-SDI capture device for post-production and streaming pipelines. With 8-, 10-, and 12-bit HDR support and compatibility across macOS, Windows, and Linux, it drops into existing NLE workflows without additional conversion hardware.

Product Description

The UltraStudio 4K Mini links a Thunderbolt 3 computer to SDI and HDMI sources for capture, playback, and monitoring. As an HDMI to Thunderbolt 3 video capture interface, it handles both compressed and uncompressed video and supports most popular codecs, letting integrators standardize on one device across multiple edit bays. A built-in 3-inch LCD shows signal, audio, and status information, while front-panel controls, a 3-pin XLR audio input, and an SD UHS-II card reader support both facility and field use. It functions as a DaVinci Resolve capture and playback unit — the free DaVinci Resolve version and Blackmagic Desktop Video software are included via download — and also supports Final Cut Pro, Adobe Premiere Pro, and Avid Media Composer. RS-422 deck control plus 16-channel SDI and 8-channel HDMI embedded audio make it suitable for broadcast video capture for editing workstations and review rooms. Thunderbolt 3 supplies up to 45W to trickle-charge a connected laptop, reducing cabling in mobile deployments.
