Red footage in Nuke

Discussions - Using ACES VFX

Hi,

The current project I am in is using Red Helium but unfortunately I am super unfamiliar with it. Already had some study but still quite confused with RED its own colorspace. I ask these separately.

  1. ACES:
    It makes me so confused here. I select “Input - RED- REDLog3G10 - REDWideGamutRGB”, and I want to know the steps separately so I put an ociocolorspace to linearize it with “Input - RED - Curve - REDLog3G10” then other ociocolorspace to covert RWG to ACEScg with “Input - RED - Linear - REDWideGamutRGB”. In my understanding these two results should be the same but they don’t.

  2. Linear-sRGB:
    In some projects we stick with linear-sRGB space. So far what I know is bring the r3d in → set to “Log3G10” in colorspace → use colormatrix from RWG ro sRGB using online app(https://www.colour-science.org:8010/apps/rgb_colourspace_transformation_matrix)
    And it is in linear-sRGB now. I’d like to know am I right with this.

Many Thanks.
