OCIO Config Working Group Meeting Notes

  • Camera Vendor CLF IDTs:

    • Carol pinged Panasonic, Sony, Canon. Not hearing a ton of response, we are going to make PRs and send them to the vendors for review at this point. Doug will take point there. 

    • Doug - for the Canon one, it will require a LUT. We could make a built-in for OCIO 2.2, but first version will likely be supported by OCIO 2.1. 

    • Doug - please review the blackmagic PR ASAP, will follow that template for the other PRs.

  • Studio config (pr #59):

    • Thomas implemented new naming convention, updated studio config spreadsheet. It's all working pretty well.

    • Note for future: the CG config spreadsheet and Studio spreadsheet are very similar - might consider combining in the future

    • https://docs.google.com/spreadsheets/d/1nE95DEVtxtEkcIEaJk0WekyEH0Rcs8z_3fdwUtqP8V4/edit?usp=sharing

    • For the camera colorspaces that are just primaries or curve - should they have separate CLFs? What should the ID be for the CLF?

    • Doug to propose in PR, will be open for comment on naming conventions 

    • Curve doesn't really apply for interchange - could see not needing a CLF for those 

    • Zach - curve could still be useful for shaper spaces for LUT baking, etc

    • With new OCIO, can go linear to log with no issue - if you need a LUT1D, better to go the other way

    • Doug, Carol, Zach, to work through updating spreadsheet with new names and aliases and categories

  • Colorspace naming conventions:

    • Proposed names in PR #58

    • Michael - are we aiming for consistency in naming - like primaries, encoding, content

    • Group: basically yes, aiming for the most important bit first, followed by encoding delineations, and connection spaces at the end

    • Old names will be in the aliases to help in connecting the dots

    • Doug - Linear delineation. Does it make sense to have at the end? Right now it's P3-D65 - Linear. Should it be Linear - P3-D65?

    • Thomas - should we switch the camera spaces instead to be consistent?

    • Kevin: linear is a bit different than texture or display which are "use cases" and linear is an encoding

    • Doug - proposing not having a dash in the linear name - so Linear P3-D65 instead of Linear - P3-D65. Could help with confusion.

    • Group decided to wait on further naming changes until spreadsheet updates are made to include more spaces - and details like family and aliases so we have a good idea of the whole picture.
