ACES 1.0 OpenColorIO config - Siggraph 2015

  1. 1.  ACES 1.0 OpenColorIO config Haarm-Pieter Duiker Duiker Research
  2. 2. Resources http://www.oscars.org/aces Documentation, Google group https://github.com/hpd/OpenColorIO-Configs OCIO configs
  3. 3. Basic ACES system
  4. 4. Detailed ACES System
  5. 5. Mapping ACES to OCIO ColorspaceTransform Colorspace Colorspace / Display / View TransformTransform / Look Colorspace OCIO concepts ACES components
  6. 6. Configuration Origin An ACES release is defined by a set of CTL files that define the transforms in the release. Python scripts, provided with the config, bake the results of the ACES CTL transforms into LUTs and wrap the results in an OCIO config structure
  7. 7. Configuration Structure Colorspaces grouped in Families Displays / Views Roles
  8. 8. Families of Colorspaces Family ACES ADX Look Output Input Utility Roles Aliases Colorspaces ACES2065-1, ACEScg, ACEScc, ACESproxy ADX10, ADX16 0.1, 0.2, and 0.7 ACES Look Transforms sRGB (D60 Sim.), Rec.709, Rec.2020, etc. ARRI, Canon, GoPro, Panasonic, RED, Sony Shapers, Generic spaces Aliases to the OCIO ‘role’ assignments Alias names with all lower case and no spaces.
  9. 9. Displays / Views • sRGB (D60 sim.) • DCDM • DCDM (P3 Gamut Clip) • P3-D60 • P3-DCI • P3-D60 PQ 1000 nits • P3-D60 PQ 2000 nits • P3-D60 PQ 4000 nits • Rec.2020 • Rec.709 • Rec.709 (D60 sim.) • Diagnostic Views • Raw • Log A single ‘ACES’ Display with views for each ACES Output Transform
  10. 10. ACES 1.0 OCIO config in Applications Config usage tested in • Nuke • Maya • Modo • Mari • Fusion Config generation tested on • OSX • Linux
  11. 11. ACES 1.0 in Nuke
  12. 12. ACES 1.0 in Nuke
  13. 13. ACES 1.0 in Maya
  14. 14. ACES 1.0 in Maya
  15. 15. Extras Pre-baked LUTs ● supporting ACES in applications that don’t (or didn’t) support OCIO ● Flame, Lustre, Houdini, Maya, Photoshop
  16. 16. Python scripts Python scripts generate OCIO configuration from CTL files that define the ACES transforms Allow customization of • LUT resolution • Display / View structure • Custom Looks
