  Color Management for VFX pipelines

  Posted by Jim Bachalo on February 16, 2023 at 7:42 pm

  For linear exrs rendered from Unreal, what is the best color management workflow?

  I have been using William Faucher’s non-ACEs linear exr workflow

  In Unreal disable tone curve before render and then

  Color science > ACEScct

  ACES Input Transform > none

  ACES Output Transform > Rec.709

  And then right clicking clips > ACES Input Transform > Color Space Conversion > sRGB Linear

  Would there be any advantage or use for CST nodes instead?

  Hey Jim,

  Personally, I tend to use the CSTs when grading because, as a colourist, I like to have full control of the transform functions. That said, it requires a bit more understanding of the said transform functions, as well as a bit more time to set them up correctly. if you are interested in knowing more about the CST, let me know!

  one thing that I noticed in Faucher’s process is that he is setting the output to Rec709. You should set it to Rec709 Gamma 2.4 instead.

  Finally, I would probably recommend you use the ACES workflow, as that allows for more colour fidelity when moving from one software to the other. This last part, though, is not mandatory.
