Minutes

Meeting called to order at 11:05am EST.

1.5 is released! Good PR!

• Need to push release to github

• Paul is willing to work on a promo "getting started" video – will work with Gary

Technical Matters

• What do we hope to get done by this time next year?

•  

  • Template project for users with video

  • Color extension implementations and shakeout (Phil, J-P?)

  •  

    • Phil & Paul have been implementing it, may need changes

    • Track OCIO developments: ACES2,

    • Follow nanocolor project -- could do a nanocolor implementation in our example

    • Paul's implemented part of this in a new Silhouette release, but it only tells plugins what they're getting, doesn't handle output or negotiation. So it's the very simplest possible host implementation, but it is conformant (per J-P).

    • Phil also is working on it in Filmlight.

  • USD: could we build a bridge?

  •  

    • Plugin running in a USD host, host makes USD stage available to plugins, then plugin can add/edit layers

    •  

      • J-P could use this in SynthEyes and Mocha

      • Could use to transfer 3d camera data

      • Might not be an image effect at all, but for camera tracking could use both images & USD

      • Autograph might also want this, see Pierre

    • Subcommittee: Paul & J-P

  • Dennis: OTIO effects in project interchange, using OpenFX - who can help drive that?

  •  

    • Could even help get effects into on-set shots, like an EDL/CDL with effects

    • Could Dennis drive this? I'll back him up

    • Paul worked on AAF committee, it was complicated to deal with

    • Find the discussion on OTIO: https://github.com/AcademySoftwareFoundation/OpenTimelineIO/discussions/921

    • https://github.com/AcademySoftwareFoundation/OpenTimelineIO/issues/331

  • Metadata

  •  

    • Paul: need prop introspection (given name, get type and given suite, get all props)

    • Should it be an existing prop system or something else?

    • Paul will experiment with it

  • What about prop introspection?

  •  

    • Add a processor that runs over the headers, produce JSON

    • TODO I'll write a doc script to go through the docs & extract some magic tag, produce JSON w/ prop, type, related suite/action

    • Then the host can build a runtime mapping (we could spit out C++ util)

    • We rev the property suite to use that mapping

    •  

      • Clip props just get extended, & metadata suite isn't needed as a separate thing.

      • Might need to support "property list" property datatype, or ClipGetMetadata

      • Could a property value be of type propertylist? Maybe just use analogy ClipGetImage

    • Paul will try this

  • First ARM64 Windows host & plugin (BlackMagic?)

  •  

    • What about Natron?

  • All: please review github, close issues & PRs.

  • Paul will miss next month, will have some metadata for following meeting

Organizational Matters

• None

Misc

Meeting adjourned at 11:58am EST
