Release Plan

VFX Reference Platform deadline is Sept 30, configs done by Sept 16th

#148: Add viewing rules to the ACES configs

  • Viewing rules are not heavily used yet, Autodesk projects have them, OIIO could use them

  • We need to document what we want the rules to be.

  • Remi: goes hand in hand with the File rules additions - #155

#146: Add DJI color space from aces-input

  • Scott: there are also other CSCs that have been added to ACES - Leica, Oppo, etc. What should be included?

  • Thomas - we should at least add them to the spreadsheet

  • Kevin - if it doesn’t have a built-in, we should say “not this time”

  • We should try to add the DJI one at least. Others out of scope.

#133: Add a virtual_display to the ACES configs

  • Should be very easy, Thomas to verify

  • Which views we want in the Virtual Display? Which are appropriate for an ICC profile? Will be different for the CG and Studio configs.

  • Doug will add exactly what should be added to the issue.

#145: Where is sRGB 2.2 Gamma Display?

  • Agreed to add Rec. 709 Gamma 2.2

  • We will wait on P3 with Gamma 2.2 for now, pending documentation updates from Apple

  • Should be easy, is already in the spreadsheet

#153: Display color spaces should mirror rather than clamp negatives

  • Need to add display color spaces to accomplish

  • Would only mirror and not clamp

  • Thomas - trying to think through consequences of not clamping for things like Unreal, etc

  • Carol - folks can still add a clamp post display if they want

  • Doug - if you’re going out integer, you’re likely clamping anyway.

#154: Update color spaces to use new attributes

  • For AMF - likely need to re-write to use the JSON file instead

  • Scott happy to help here if changes need to be made to leverage

  • Only using the ones already in our configs

  • This is likely the biggest chunk of work for this release

  • We should separate the fields into their own issues possibly

  • Group agrees to not add icc_profile_name for now

#155: Expand the file rules to handle integer formats

  • Might want this as an optional feature

  • On by default, but enable it to be turned off

  • We should document this well, and have UI/UX examples

  • It’s about sensible defaults, not file introspection

#157: ARRI LogC4 ACES ID typo

  • Easy fix, will do
