Why go to DJI log at all if Resolve can convert it to whatever it likes? Go straight to ACES in Resolve.
(note that I have no understanding of how Resolve works, but my hunch is you’ll have a harder time dealing with esoteric color spaces like DLog in Flame)
Yep, what Andy say. Resolve treats .dngs from DJI copter like raw from first BMD cameras (back in the days they shoot in .dng). Just convert them to Alexa LogC prores .movs using Davinci YRGB color managed project and have fun in Flame. Or go straight to ACES with .exrs.
