Re: nuke-default's sRGB and ACES 1.1 sRGB

Hi Gonzalo,

IPP2 is the RED Image Processing Pipeline #2, introduced three or four years ago which is closer to the ACES concept.
If you read in RED footage choose the settings at the attached image in Nuke's Read node and you are on the safe side.
To get those settings in the Read Node color space line choose: (Colorspaces) --> Input --> RED --> REDLog3G10 -

Hi Gonzalo,

second thought only to get us on the same page: The problem may be raised in the input section.
Is it a RED Sequence you are reading in?
Yes, it was a RED sequence, but I was just testing it with scene_linear.
I hope the thoughts may help. The topic using pre-ACES.1.0.3? (Nov. 2016)
RED conversions is complex. We did some research and would recommend using the IPP2 color pipeline
in the (ACES) Nuke input. All settings are automatically correct. There should be no problem at all, although the ACES IDT
keeps the RED material very slightly reddish.

What's the IPP2 color pipeline?  Is it some Nuke node, some OCIO config
transform or the IPP2 function that appears in the RED SDK?
