Why are there 2 Color Space & Gamma Curve options in PP

[Tom S]

In PP (effects control, master .r3d tab), using DSMC1 Legacy, I have noticed there are always 2 options for Color Space and Gamma Curve. The top ones seem to be active and have options in the drop down menu, but the bottom selections only show the IPP2 RedWideGamutRGB and Log3G10. Anyone know why the second set is there as they don't actually seem to do anything.

Tom,

Maybe it's PP version of a "COLOR SPACE TRANSFORM" from one Color Space and Gamma to another Color Space and Gamma. The Default Color Space and Gamma for IPP2 is RedWideGamutRGB/LOG3G10 so maybe thats why it can't be changed. Or Maybe the Top portion is what PP detected as the Color Space and Gamma of the clip you are currently using before transforming it into RWG/LOG3G10.
