URSA Cine 12K LF Specs, Media & Workflow
Blackmagic Design has a history of shaking things up. From democratizing color grading with DaVinci Resolve to putting RAW recording in compact cameras, they’ve consistently challenged the status quo. Now, with the URSA Cine 12K LF, they’re stepping firmly into the high-end cinema arena, aiming not just to compete, but potentially to redefine expectations.
This article covers the first part of our deep-dive “Official Demo,” where cinematographer Shane Hurlbut, ASC, and Blackmagic Design’s Tor Johansen get hands-on, exploring the camera’s physical characteristics, media capabilities, and foundational technology. We compare it to its predecessor, the URSA Mini Pro 12K, and see how it stacks up against industry benchmarks. This isn’t just a spec rundown. Rather, it’s about understanding the why behind the design choices and how they impact you, the filmmaker.

FIRST IMPRESSIONS: BUILD, BOOT-UP & PHYSICAL FEEL
Right away, the URSA Cine 12K LF feels different. It presents a more substantial, professional build than the URSA Mini Pro line. Constructed from magnesium alloy and carbon fiber, it finds a good balance between durability and weight. The body weighs around 8 pounds, about two pounds heavier than the Mini Pro 12K, but still very manageable for various setups, including handheld.

Measuring roughly 6.25″ wide x 6.25″ high x 10.5″ long, it’s slightly larger than the Mini Pro. This increased size accommodates better cooling, a more robust internal structure, and a more ergonomic layout with ample buttons and professional connections.
Boot-up time is a small but crucial detail on set. The URSA Cine 12K LF boots in a respectable 8 seconds. While the older Mini Pro 12K is slightly quicker at 6-7 seconds, both are significantly faster than many other professional cinema cameras that can take 20-30 seconds. In those moments when the director yells “Roll!” unexpectedly after a battery swap, a quick boot-up matters.
MEDIA & STORAGE: TAMING THE 12K BEAST
Recording 12K RAW, especially at high frame rates, generates enormous amounts of data. Blackmagic tackled this head-on with a new, custom-designed 8TB Media Module (with a 16TB option coming). This isn’t just about capacity; it’s about speed. The module boasts a sustained write speed of 6 gigabytes per second.
Why is this speed critical? It ensures the camera can reliably record at its highest quality settings — maximum resolution, minimum compression, high frame rates — without dropping frames, an issue that plagued earlier high-resolution cameras using standard media like CFast.

Blackmagic clearly understands that the recording medium is just as vital as the sensor itself. This proprietary solution ensures reliability. Another workflow advantage: the URSA Cine 12K LF requires no user black shading or pixel mapping, saving valuable time on set and simplifying camera prep.
RECORDING TIMES, COMPRESSION & BIT RATES: FLEXIBILITY IS KEY
Blackmagic RAW (BRAW) offers a fantastic balance between image quality and file size efficiency. The URSA Cine 12K LF provides various compression levels, from a visually lossless 3:1 ratio up to a highly efficient 18:1. This gives filmmakers tremendous flexibility. Need maximum quality for VFX plates? Shoot 3:1. Need to record for extended periods for a documentary? 18:1 works remarkably well.
On the 8TB module, 12K RAW at 3:1 compression yields about 2.2 hours of record time, while 18:1 stretches that to an incredible 13 hours. Planning your media needs is crucial, and Blackmagic offers an online calculator to help estimate recording times based on resolution, frame rate, and compression.
Even at its highest quality settings, BRAW keeps bit rates manageable compared to some other RAW formats (the camera maxes out its output at 4GB/s in extreme scenarios). This efficiency translates directly to a smoother post-production workflow, requiring less demanding hardware for editing and grading.
ROLLING SHUTTER: ALMOST GLOBAL PERFORMANCE?
A key question for any camera is its rolling shutter performance. Unlike a global shutter (which captures the entire frame instantly), a rolling shutter scans the image sequentially. This can cause the “jello effect” with fast motion. The URSA Cine 12K LF uses a rolling shutter, but Blackmagic has mitigated the issue significantly with an exceptionally fast sensor readout speed.
How fast? Fast enough that rolling shutter artifacts are minimized to the point of being nearly imperceptible in most shooting situations. The faster the sensor reads the image from top to bottom, the less distortion occurs. Furthermore, shooting in 8K mode leverages the camera’s pixel binning, making the effective readout speed even faster, further reducing any potential rolling shutter issues.
While not technically a global shutter, the performance is remarkably close, offering a practical solution for confidently shooting action and dynamic movement without significant distortion concerns. For those wanting extreme technical detail, resources like CineD offer in-depth rolling shutter measurements.
THE BOTTOM LINE (PART 1): A SOLID FOUNDATION
This initial look reveals the Blackmagic URSA Cine 12K LF as a thoughtfully designed, professional cinema camera. The robust build, innovative high-speed media solution, flexible recording options, efficient BRAW codec, and impressive rolling shutter performance lay a strong foundation. It’s clear that Blackmagic isn’t just adding features; they’re addressing real-world filmmaking challenges and building an ecosystem designed for high-end production.
But this is just the beginning. How does the image actually look? How does it handle extreme exposure? What about ergonomics and lens compatibility?
