Hi, I would like to share my footage on the same issue.
Origial RED R3D : DaVinci ACES ; ODT = Rec.709
Origial RED R3D : DaVinci ACES ; ODT = Rec.709, with "LMT.Academy.FixHighlights.dctl"
ACES AP0 in LogFilmScale ( No RRT+ODT ) just want to see image data after IDT.
DaVinci YRGB , REDWideGamutRGB + Log3G10 then apply default AlexaLogC_709 LUT.
And here is the original (trimmed) r3d file from camara.
I'm still trying to fix this artfactes.
