Resolve 17.4.1/2 build 9 - ARRI input LUT always on

PostWed Nov 24, 2021 9:44 am

ARRI Amira input LUT can't be disabled. Windows 10 Resolve 17.4.2 build 9 and previous version BUG

No input or output LUTs are active in project settings. All footage from various cameras are presented with their LOG image when browsing in Media Storage. Same thing when imported into Media pool and edited in the timeline. However ALL footage from ARRI Amira now has the LOG -> Rec709 LUT applied already when browsing through the Media storage and I can't find a way to disable it. I media explorer in Windows all files are displayed in LOG C when opened in VLC.

Are you working in a color managed project?

Thanks for your answers.

Suddenly the issue went away. New thumbs were loaded on the Arri clips in Media Storage when clicked and the Log was correctly viewed both in media pool and storage.

However now the issue is back when reopening Resolve some days later. Can't replicate what I did to get rid of the problem.

The strange thing is that Resolve handles all files but the Arri files the same: viewing them in Log. Arri files are only visible in Rec709.

Ok - I enabled and then disabled "Davinci YRGB color managed" in Project Settings - Color management - Color science and now all clips are showing with the correct Log image
