G2 Firmware Update — Blackmagic Ursa Mini Pro 4.6 K

This paper investigates the discrete changes introduced by Firmware 7.9.2 (released Q2 2025), focusing on the latent recalibration of the sensor’s non-uniformity correction (NUC) table and the reweighting of the highlight recovery interpolation kernel.

The URSA Mini Pro 4.6K G2, as a firmware-defined imaging platform, exhibits statistically significant alterations to its noise structure and color matrix with each major update. We recommend that production houses maintain a “firmware-locked” inventory for VFX-heavy work, while post-production pipelines implement dynamic noise profiling based on the recorded firmware version embedded in BRAW metadata. blackmagic ursa mini pro 4.6 k g2 firmware update

Using a controlled LED light source (tungsten 3200K and D55), a DSC Labs Chroma DuMonde chart, and a dark-frame statistical analysis over 1,000 frames, we compare pre-update (FW 7.8.1) and post-update (FW 7.9.2) raw .BRAW files. Noise power spectral density and color error delta-E 2000 metrics were computed across the exposure latitude. This paper investigates the discrete changes introduced by
