On a quiet late-July morning, Blackmagic Design added a small new chapter to the long human effort of moving moving pictures from one place to another, releasing a family of compact Thunderbolt 4 interfaces that can capture, play back, or do both at once. The three models divide the work by direction, letting a laptop or desktop take in video from cameras, consoles, and aging tape decks, or send finished images out to monitors and broadcast switchers. Their appeal lies in the modesty of the promise: broadcast-grade quality, a single cable, and a starting price of $395 that brings studio-grade
Blackmagic Design Launches UltraStudio Mini 12G Thunderbolt 4 Capture and Playback Family
Capture, process and output video in real time over one cable
So what is actually new here?
Three small Thunderbolt 4 boxes: one records, one plays back, one does both at once. All handle up to 2160p60 and start at $395.
Why does the Replay model stand out?
It captures and plays simultaneously, with separate fill and key outputs and a monitoring output. It supports live replay in DaVinci Resolve 20.
Worth noting the feature list mentions Resolve 21 while the text says Resolve 20 for replay. The source doesn't explain that.
What's fill and key, in plain terms?
Two signals: the picture and a transparency mask. A switcher uses them to lay graphics over video with smooth edges.
Everything about quality, like smoother blending or sharper keying, is Blackmagic's own description. No independent testing is cited.
And the AI processor idea?
The bidirectional link lets a computer take video in, process it and send it back out in real time.
That's a stated capability, but no specific AI workflow or performance figure is given.
Anything on price beyond $395?
Only that it's the starting price, excluding duties and taxes. The source doesn't give per-model prices.
Le Pouls
- A new trio of UltraStudio Mini 12G devices arrives, promising capture and playback up to 2160p60 through one Thunderbolt 4 cable.
- Live productions face the tight pressure of replays, stingers and graphics that must blend cleanly on air in real time.
- The Replay model is positioned to let a computer act as a live graphics or AI processor, bridging a switcher's multi-view with automatic stingers.
- Resellers worldwide are already stocking the models from $395, and the industry is watching whether streamers and broadcasters take the bait.
On a quiet late-July morning, Blackmagic Design added a small new chapter to the long human effort of moving moving pictures from one place to another, releasing a family of compact Thunderbolt 4 interfaces that can capture, play back, or do both at once. The three models divide the work by direction, letting a laptop or desktop take in video from cameras, consoles, and aging tape decks, or send finished images out to monitors and broadcast switchers. Their appeal lies in the modesty of the promise: broadcast-grade quality, a single cable, and a starting price of $395 that brings studio-grade capability within reach of smaller creators. Whether this quiet tool reshapes live production or simply becomes another reliable part of the toolkit will be revealed by the people who choose to use it.
Blackmagic Design has released a new family of compact video interfaces called the UltraStudio Mini 12G, three Thunderbolt 4 models built to capture and play back broadcast-quality video. They are available now through resellers worldwide, starting at $395 before local duties and taxes.
The lineup divides the work by direction. The Mini Recorder 12G only takes video in, from 12G-SDI and HDMI, serving live streamers, archivists digitising old broadcast tapes, and anyone recording from a game console. The Mini Monitor 12G only sends video out, feeding monitors from editing software and carrying fill and key signals for broadcast graphics. The Mini Replay 12G does both at once, adding independent fill and key outputs for live replays in DaVinci Resolve 20, where a switcher's multi-view can be replayed with automatic stingers.
All three carry video, playback and power over a single cable, and Thunderbolt 4 supplies the bandwidth for higher resolutions and deeper colour. With 10-bit precision, the devices offer finer green screen keying and cleaner colour correction, and they cover SD, HD and Ultra HD up to 2160p60. Broad software support, from DaVinci Resolve to Final Cut Pro and Premiere Pro, means editors are not locked into a single workflow, and a free SDK lets developers build their own tools.
CEO Grant Petty said customers had long asked for the Mini line to handle higher resolutions and more demanding work. The open question is whether live production and streaming users will embrace the lower-cost Replay model in practice.
Blackmagic Design has announced a new family of compact video interfaces, the UltraStudio Mini 12G, three Thunderbolt 4 models for capturing and playing back broadcast-quality video. They are available now through Blackmagic Design resellers worldwide, starting at $395, excluding local duties and taxes.
The three models split the work by direction. The UltraStudio Mini Recorder 12G is input only, capturing from 12G-SDI and HDMI in SD, HD and Ultra HD. The company points to live streaming with software such as Open Broadcaster, archiving from old broadcast decks into editing software or the bundled Media Express application, and recording from game consoles.
The UltraStudio Mini Monitor 12G is output only, playing back to 12G-SDI and HDMI. It is aimed at monitoring playback from editing software. It has dual 12G-SDI outputs that carry fill and key for broadcast graphics, automatically converting the alpha channel in a graphic into a key output.
The third model, the UltraStudio Mini Replay 12G, is 12G-SDI only and can capture and play back at the same time. It adds independent fill and key outputs plus a dedicated 12G-SDI monitoring output. It supports the live action replay features in DaVinci Resolve 20. Blackmagic suggests connecting its input to a switcher's multi-view, then replaying with automatic stingers through the fill and key outputs. Because the Thunderbolt link is bidirectional, the Replay model can capture, process and output video in real time, which lets a computer act as a real-time graphics or AI processor.
All three models carry video capture, playback and power over a single Thunderbolt cable. Blackmagic says Thunderbolt 4 supplies the bandwidth for high resolutions, deeper bit depths and frame buffer formats such as 4:2:2:4 and 4:4:4:4. Internally there is hardware support for both RGBA and YUVA buffers. With RGBA graphics, pixels are transcoded to YUV 4:2:2:4 at full 10-bit precision on both outputs. The two SDI outputs then feed a live production switcher, where the key output gives smooth blending of transparent elements. The company describes this as ideal for broadcast graphics and stingers.
On formats, all models handle SD, HD and Ultra HD standards up to 2160p60. In SD that means 525i59.94 and 625i50. In HD it covers 720p, 1080i and 1080p up to 1080p60. For 3G-SDI sources, users can switch between level A and level B. Blackmagic notes that 10-bit is the most common television standard, representing colour with four times the precision of 8-bit, and cites sharper green screen keying, cleaner VFX compositing and better colour correction. Most software supports Apple ProRes, DNxHD or uncompressed 10-bit, so users are not tied to one file format.
Software compatibility is broad because the devices use the DeckLink API. Blackmagic lists DaVinci Resolve, including its live grading feature for capturing, correcting and outputting live; Final Cut Pro; Media Composer; Premiere Pro; and the effects tools Fusion, After Effects and Photoshop. Fusion can be downloaded free inside DaVinci Resolve.
Developers get a free SDK for Mac, Windows and Linux, with low-level hardware control and higher-level interfaces for common tasks. Manufacturers can contact Blackmagic's OEM team for developer support and bulk discounts, while lower-volume buyers can use the reseller network.
Grant Petty, Blackmagic Design's CEO, said customers had been asking for UltraStudio Mini with support for higher resolutions and more demanding workflows. What to watch next is whether live production, streaming and replay users adopt the lower-cost Replay model in practice.
