Let me clarify...the FREE version of Resolve WILL handle HDR, HLG, or PQ. You can acccess the full color managed menu, change anything to anything else, and export/render out as any option shown, SDR, HDR, HLG, 709 etc. What I meant was the process of putting HLG (iPhone DV) into Resolve, and spitting out HDR10, as demonstratic as the bais of the video, is the best way to deal with these iPhone clips, if you wish them to be viewable as HDR by as many people as possible. There are some scopes limitations witn the free version, but the process of simply color space converting the iPhone files and exporing them as HDR10 is availabel in Freesolve.
