DESCRIBE THE BUG: The S-Log3/S-Gmaut3.cine LUT is underexposing the image when the codec is ProResRAW (in my case from an A7SIII). The same video file taken from the camera (XAVCS-I) is working fine.


TO REPRODUCE: Shoot ProResRAW on an A7SIII ; settings for camera and Atomos Ninja V are S-Log3/S-Gamut3.Cine Set the camera to ISO 12800 Import to ProResRAW footage to Final Cut Pro, select the matching LUT (make sure to select the .cine LUT).


EXPECTED BEHAVIOUR: Normal LUT conversion, should have brightness similar to the normal S-Log3/S-Gamut3.cine LUT.
