Version 1.2.10 — 15 October 2026
Fixes small colour changes getting stuck in temporal denoising. The accumulated image now keeps
fractional values in half-float GPU textures instead of rounding to eight bits on every frame.
The final NV12/YUY2 output formats, filtering strength and number of processing passes are unchanged.
The fix applies to the shared Windows/Linux picture pipeline whenever denoising is enabled.
A compiled GPU regression reproduces the old error and verifies convergence after the fix:
mean chroma error for a small colour step fell from 2.635 to 0.439 studio-range codes. Existing
moving-detail, edge, correlated-noise and reset tests pass. This is a correction to colour
accumulation, not a claim of a large overall noise reduction: three recorded scenes showed
temporal brightness variation changing by +1.81%, -1.73% and +0.66% respectively.
On an RTX 3060 Ti, a live 1920x1080 bokeh test delivered 59.993 fps over 600 measured frames
after 30 warm-up frames, with no reported dropped frames and 8.927 ms mean GPU compute.
The change needs about 15.82 MiB of additional GPU history memory at 1080p; performance on
other hardware depends on its memory bandwidth and processing capacity.
Existing camera settings and calibration are preserved. No new camera firmware is required.
Windows, Linux and macOS installers remain available; the macOS firmware loader itself is unchanged.
