Hey Everyone! today we are sharing this tutorial by Zak, a 3D generalist based in Los Angeles. In this tutorial, Zak shows you how we can use a simpler ACES workflow from Cinema 4D & Redshift into After Effects.

On-line, you can find many videos about how to use ACES color space, but in this new video Zac shows you their own method, which could be an alternative simple to use.

In this tutorial, we will see you the color space workflow for ACES. Zak will demonstrate how to set up an ACES workflow between Redshift in Cinema 4D, then composite in After Effects.

NEW SIMPLIFIED WORKFLOW: ACES in After Effect with Color Management On

  • 1. Under “Project Settings” “Color” tab “Depth: 32 bits”; Working Space: sRGB (or Rec.709); “Linearize Working Space” checked ON
  • 2. Drag your .EXR footage into a new 32bit comp; “View” “Use Display Color Management” should be ON
  • 3. Add a new adjustment layer above your .EXR; Add the “OpenColorIO” effect. For “Configuration” browse to your “config.ocio” under the latest Aces folder in the OpenColorIO configs you downloaded.
  • 4. In the OpenColorIO Effects Panel under “Input Space” select “ACES – ACEScg”; In the “Output Space” select “Output – sRGB” or “Output -Rec.709” or whatever your output space is going to be.
  • 5. Add a new adjustment layer on top; Add the “Color Profile Converter” effect. Set both the input and output space to your output color space chosen in the previous step (i.e. sRGB, Rec.709); Check ON “Linearize Output” checkbox. (This negates the double gamma curve applied by After Effects and OCIO plugin)
  • 6. Any color correction should be applied to an adjustment layer or layers above the .EXR/footage layer but below the OpenColorIO layer; color corrections are the meat of the sandwich. .EXR layer and OpenColorIO are the bread.

OLD WORKFLOW: ACES in After Effects with all Color Management Off

  • 1. Under “Project Settings” “Color” tab “Depth: 32 bits”; “Working Space: ACEScg”; “Linearize Working Space” checked ON
  • 2. Import your rendered .EXR and/or footage, Right click and select “Interpret Footage – Main”; Under “Color Management” tab check ON “Preserve RGB”
  • 3. Drag your .EXR or footage into a new 32bit comp. Under “View” menu UNcheck “Use Display Color Management”
  • 4. Add a new adjustment layer above your .EXR; Add the “OpenColorIO” effect. For “Configuration” browse to your “config.ocio” under the latest Aces folder in the OpenColorIO configs you downloaded.
  • 5. In the OpenColorIO Effects Panel under “Input Space” select “ACES – ACEScg”; In the “Output Space” select “Output – sRGB” or “Output -Rec.709” or whatever your output space is going to be.
  • 6. Any color correction should be applied to an adjustment layer or layers above the .EXR/footage layer but below the OpenColorIO layer; color corrections are the meat of the sandwich. .EXR layer and OpenColorIO are the bread.
  • 7. When ready to export; “Add to Render Queue”; Under “Render Queue” tab, click “Output Module – Lossless”, under “Color Management” tab check ON “Preserve RGB”

ACES is a free, open, device-independent color management and image interchange system that can be applied to almost any current or future workflow. It was developed by hundreds of the industry’s top scientists, engineers, and end-users, working together under the auspices of the Academy of Motion Picture Arts and Sciences.
