OCIO Config Working Group Meeting Notes

  • RED CLF PR:
    • Merged! Doug will work on the Blackmagic PR next.
  • Camera Vendor followups:
    • Waiting to see what Canon wants to do about half-domain LUT1D vs. normal 1D
    • Email followups sent to Sony and Panasonic
    • New ARRI Log space should work with the built-in Camera Log Transform
  • Naming discussion
    • Having discussions with OpenEXR around OCIO colorspace metadata in EXR files
    • Proposal to store OCIOConfigName and OCIOColorSpaceName in the header
    • Also, working on a built-in config for the core OCIO library
    • So what to name the config is important - it needs to be compatible with a URI, convey purpose, ACES version, config requirement, OCIO version, etc.
    • Currently, the "name" object in our configs is much more human readable
    • Should move to use basename (filename) for the config name object instead, and put the human readable version in the description field.
    • Color space naming
      • We should revisit soon, all of the naming is slightly different from ACES IDT to CSC to OCIO
      • Joseph/ARRI prefers:
        • ARRI LogC3 AWG3 (EI800)
        • ARRI LogC4 AWG4
      • Re: input in the color space name - group feels that it's not really needed, but maybe a build option for people who want it? Or maybe as an alias would be better, just to be safe
      • As far as the naming, currently based on ACES dev - should sync with the ACES IDT group to discuss updates for ACES 2.0. Carol will start an email thread with Josh Pines
  • URN Specification
    • Transform platform re-purposes to Transform type
    • Leaving order of the URN the same
    • Doug will update the CLF Formatting doc
  • Possibly adding Leica L-log to the config/built-in transforms (should create a github issue for tracking)
  • Items for next meeting agenda:
    • Info
