I have a piece of Rec.2020 footage. I am using DaVinci Resolve to split the video into separate scenes. After I prepare my timeline, I export but every time I do so, I am only getting 8 bits and the colour isn't correct. I have set the preferences to export Rec.2020. My video is set to Rec.2020 when I import it. I have tried using H.265 with HDR10+ selected and even DNxHR. I cannot help but notice that there is a drop-down that is greyed out that says BT.709. Is there a way I can export the original Rec.2020 without having to recolour it?
