Blackmagic Design has released the UltraStudio Mini 12G family, three compact Thunderbolt 4 capture and playback devices built for broadcast use in SD, HD, and Ultra HD up to 2160p60. The lineup consists of the capture-only UltraStudio Mini Recorder 12G, the playback-only UltraStudio Mini Monitor 12G, and the bidirectional UltraStudio Mini Replay 12G, which combines simultaneous 12G-SDI capture and playback with dual independent fill and key outputs, a dedicated monitoring output, and support for the live action replay features in DaVinci Resolve.

The new family arrives only a few weeks after the company introduced the entry-level UltraStudio Express 3G, and it slots in directly above those USB4 devices. Where the Express models top out at 1080p60 over 3G-SDI, the UltraStudio Mini 12G generation moves to multi-rate 12G-SDI and Thunderbolt 4, bringing Ultra HD workflows, deeper bit depths, and broadcast graphics capabilities to the same pocketable form factor. It also continues a busy year for Blackmagic Design’s broadcast infrastructure push, following the wave of SMPTE-2110 and 100G Ethernet products the company revealed around NAB 2026.

Three models, three jobs

The UltraStudio Mini Recorder 12G is the input-only model, capturing from 12G-SDI and HDMI sources in SD, HD, and Ultra HD. Blackmagic Design positions it for live streaming through software such as Open Broadcaster, archiving from legacy broadcast decks into an NLE or the bundled Media Express application, and even capturing from game consoles.

The UltraStudio Mini Monitor 12G is its output-only counterpart, playing back to 12G-SDI and HDMI for monitoring from editing and grading software. Its dual 12G-SDI outputs can switch to fill and key operation, automatically converting the alpha channel of graphics into a key signal, which turns a laptop into a broadcast graphics source for a production switcher.

The most interesting model is the UltraStudio Mini Replay 12G. This 12G-SDI-only unit captures and plays back at the same time over a single Thunderbolt connection. It carries dedicated 12G-SDI fill and key outputs that connect to a switcher’s downstream keyer, a separate always-active 12G-SDI monitoring output for cueing up the next replay, and a 12G-SDI input intended for live monitoring of a switcher multiview. Because the Thunderbolt link is bidirectional, the computer can also sit in the middle of a live signal chain, rendering broadcast graphics or applying AI-based processing over an incoming feed in real time.

Replay workflows in DaVinci Resolve

The Replay model leans heavily on the cut page in DaVinci Resolve, which has grown into a combined editing, media player, and replay environment. Resolve plays video files with alpha channels and outputs them as 10-bit SDI fill and key, while the multi source viewer displays time-matched clips in a multiview for fast visual browsing. New on air controls let the key output enable the downstream keyer in a switcher, so a single button can automate play-out to air, and Resolve can even trigger an automatic stinger transition. For sports replay, news graphics, and small-scale live production, that is a lot of workflow condensed into one Thunderbolt box and free software.

Thunderbolt 4 and 10-bit signal paths

All three models connect over a single Thunderbolt 4 cable that carries video and power. The interface provides enough bandwidth for high resolutions, deeper bit depths, and advanced frame buffer formats such as 4:2:2:4 and 4:4:4:4, including real-time conversion of alpha channels out to the 10-bit 12G-SDI fill and key outputs. Internally, there is hardware support for both RGBA and YUVA frame buffers; RGBA graphics are automatically transcoded to YUV 4:2:2:4 on both fill and key outputs at full 10-bit precision, which should deliver clean edges when transparent elements are keyed over video on a switcher.

The devices use the same DeckLink API and Desktop Video driver as Blackmagic Design’s capture cards, so compatibility extends to virtually all professional video software, and the company highlights the driver’s low latency for real-time bidirectional transfers. According to Blackmagic Design, the hardware can also be software updated to add new television standards later.

Formats, standards, and software support

On the format side, the UltraStudio Mini 12G models cover 525i59.94 and 625i50 in SD, 720p, 1080i, and 1080p up to 1080p60 in HD, and all Ultra HD standards up to 2160p60. For 3G-SDI sources, users can switch between Level A and Level B. Capture and playback work with popular codecs including Apple ProRes, DNxHD, and 10-bit uncompressed, so nobody is locked into a single file format.

Supported applications include DaVinci Resolve, Final Cut Pro, Media Composer, Premiere Pro, and Open Broadcaster, plus Fusion, After Effects, and Photoshop for graphics work. Every unit ships with Blackmagic Media Express for capture and playback to uncompressed YUV 4:2:2 QuickTime, AVI and DPX, ProRes, DVCPRO, and MJPEG files, along with Blackmagic Disk Speed Test for checking storage performance against television standards. A free developer SDK for Mac, Windows, and Linux rounds out the package for anyone building custom broadcast solutions. Users who need more connectivity, such as 10G Ethernet and dedicated monitoring outputs, can step up to the larger Blackmagic Media Player, which builds on the same concept.

The UltraStudio Mini 12G models are available now from Blackmagic Design resellers worldwide. The company’s announcement quotes pricing from $395, while the US product page currently lists the UltraStudio Mini Recorder 12G and UltraStudio Mini Monitor 12G at $445 each and the UltraStudio Mini Replay 12G at $559; as usual, pricing varies by region and local duties and taxes.
