  •  

    • TODO merge after this meeting

  • Ticket triage and code review

  •  

    • Issue 127 (LUTs): please comment.

    •  

      • No spatiotemporal pixel (e.g. not a vignette) but ok to depend on more than one input?

      • J-P, Phil, Greg

      • But what about replacing plugins with LUTs for commercial plugins

      • Phil will ask Greg to attend next meeting to discuss this

  • Pierre update on spatial issues

  •  

    • No progress, but Pierre talked with some folks at SIGGRAPH

    •  

      • Should we add a camera metadata suite? Work w/ other ASWF groups (USD camera, etc.)

      • Do we still support non-square pixels? Yes

      • J-P notes that Foundry is doing something with OTIO or somewhere on camera metadata (but that is only within Nuke, not useful for us) but there is an emerging lens metadata standard

  • Discuss PR #48 - optional functions in a suite

  • Color updates

  •  

    • At SIGGRAPH, Pierre met Joachim, head of ACES, they have multiple ways to do LUTs, chains of LUTs, etc.

    • Blackmagic wanted to go beyond ACES (which in their exp is not widely used)

    • BM suggested allowing custom color profiles with some simple formulas

    • J-P will meet Rohit at IBC, maybe we can all agree on a few ACES spaces

  • GPU updates

  •  

    • Pierre was going to talk w/ Rohit, but he didn't reply. J-P will follow up.

    •  

      • They're still shipping their header, should ship ours.

      • Also please open-source their example
