ISO 800 BRAW constant bitrate 3:1 4.6K scaled to UHD With BRAW this philosophy doesn’t work, as we have to use DaVinci Resolve to develop the files. Now, there is a little issue with BRAW and our standardized testing workflow, as we usually try to avoid any 3rd party software when extracting keyframes for our IMATEST analysis (other than ffmpeg) to avoid any kind of manipulation/influence of this software to the image. 12 stops can be identified above the noise floor.

Waveform plot of the XYLA21 stepchart URSA Mini Pro 4.6K G2 using ProRes XQ at ISO800. This is almost exactly the same result that I got with the previous generation UMP 4.6K in December, within 0.1 stops. At ISO800 the UMP 4.6K G2 comes in with a strong 12.6 stops of dynamic range at a signal to noise ratio of 2 according to our IMATEST analysis (13.5 stops at a signal to noise ratio of 1). 4.6K G2 ProRes XQ ISO 800 Dynamic Range ResultsĪs a first step, I analyzed the 4.6k ProRes XQ dynamic range. Also, back this summer we hadn’t established our rolling shutter test yet, so this value is, therefore, missing in our results.īefore the dynamic range test, I let the UMP G2 warm-up for 15 minutes and then performed the “black shading” sensor calibration with the lens cap on. The test was performed in June 2019 – so I have to apologize to you, our readers that I didn’t publish it earlier. So, is the new G2 going to set a new standard in our lab? Read on for our results – also, please have a look at how we test dynamic range here.

Last year when we tested the predecessor to the current G2, the UMP 4.6k G1 in ProRes and BRAW, we (back then) got the second-highest dynamic range result ever: 12.5 stops in ProRes, 12.6 stops for BRAW (for a signal to noise ratio of 2). Also, we wanted to see how it fares in our latitude test versus the first generation URSA Mini Pro 4.6K G1.

When the new URSA Mini Pro 4.6K G2 arrived at the cinema5D office this summer, we were quite curious to see if the lab results would show a difference as Blackmagic Design claims in their official press release that, “the second generation URSA Mini Pro features fully redesigned electronics and a new Super 35mm 4.6K HDR image sensor”.
