Thanks Andrew.
Does Rec 709 typically apply a gamma of 2.4? Some info suggests it can sometimes apply 2.2. In that case, what gamma is being applied if I choose Rec 709 for Output Gamma in the Color Space Transform? Is that why you specified Rec 709 with gamma 2.2? If I opt to set Rec 709 should I then set Output Gamma: sRGB to get a correction of 2.2? Is that what you meant?
If I choose the sRGB option to apply a Color Space Transform from the OpenFX tab to an URSA 4.6K LOG clip, are these the correct Settings?:
Input Color Space: Blackmagic Design 4.6K Film v3
Output Color Space: sRGB
Input Gamma: BMD 4.6K Film Log
Output Gamma: sRGB
Typically now Rec.709 is graded with 2.4 gamma, but old Rec.709 did not use 2.4. More like 1.96.
It should not be called Rec.709 anymore but BT.1886 which is basically old Rec.709 gamut with 2.4 gamma.
Your settings for sRGB are good.
Just remember that in order for all to be correct you monitor has to be set to match your Resolve setting.
