Notes

UX Meeting Slot

  • Repurposing UX meeting slot for general OCIO project use

  • Idea was maybe to make that meeting slot a general project meeting slot, for whatever needs discussion outside the TSC. Sometimes that might be UX, or Configs, or other project needs

  • Move it back to 11am PST to align with TSC meeting

Color Interop Forum update

  • Next Monday is the next CIF meeting (Feb 24) - please try to attend with opinions (smile)

  • Carol & Doug went to the last OpenEXR TSC Meeting to discuss proposal

  • Goal for the coming meeting would be to discuss a specific proposal

  • Comment on the issue if you have feedback please:

  • https://github.com/AcademySoftwareFoundation/ColorInterop/issues/4

  • Mark - who is asking for this fix?

  • Most recently, Nick Porcini at Pixar re-brought up this issue in relation to USD interop

Missing displays from the ACES 2 CTL

  • Adding missing displays from the ACES 2 CTL collection to the ACES 2 config

  • Working to get these configs finalized so we can ship these as artifacts with OCIO 2.4.2

  • Missing 4 displays each (d60/d65) - SDR DCDM (48nit 2.6g), HDR DCDM (PQ, 300nit), Gamma 2.2 rec709 SDR, Gamma 2.2 Display P3 100 nit

    • Decision: all four should be in the reference config,

    • None should be by default in the studio or CG configs

    • Decision might change based on testing for Display P3 in particular

    • And always up for feedback to make future decisions about what is included by default

  • Thomas - ordering is driven by the reference config partially, which is hard to fix

  • We should eventually merge the spreadsheets together, but that might be a lot of work and wait for 2.5 (or beyond)

  • Might not release ACES 2 built-in configs with 2.4.2, just the artifacts.

  • If we do, keep the default as the 2.4.1 configs, make the default switch with 2.5

ACES 2 optimization updates

  • Kevin still working on some things to submit a PR

  • Stylistic question about shaders - ok to introduce more functions?

  • Doug - functions are in use in other OCIO shaders, but not sure if there is a performance cost

  • Remi can help with profiling if we want to test

  • Alex Fry working on his delta frameworks, Scott Dyer will re-render images with the latest CTL just to make sure

  • Metal GPU fix merged

Meeting Recording / Transcribing

  • Group agrees to try AI meeting notes / summary / etc

  • Carol to propose some settings for the above and come back to the TSC with changes
