Minutes

Meeting called to order at 11:03am EST.

Organizational Matters

• First meeting without Dennis Adams, who has retired.

Technical Matters

• Color Space Definitions in Basic/Core

  • Pierre raised concerns over the usefulness of current basic color space definitions.

  • Prefers simple log vs non-log distinction.

  • Suggests merging HDR and Log into one bucket in some cases.

  • John-Paul discussed OCIO mappings in Mocha, agreed on avoiding tight definitions.

  • Proposal to add clear mappings in headers or documentation.

  • Agreed to provide example mappings from OCIO core to OFX basic.

  • Considered whether to treat changes as doc or header changes for versioning.

  • Decision to incorporate via color space versioning mechanism (aligned with ACES 2.0 changes).

  5. Instance Creation and Clip Change Timing

  • Pierre and Gary discussed plugin initialization issues when clips are not yet connected.

  • Issue that some hosts do not call instanceChanged after clips are connected (e.g., Resolve Edit page).

  • Proposal: hosts should ensure instanceChanged is called after project load and clips are connected.

  • Phil noted current limitations in FilmLight; agreed to implement a fix in next release.

  • General agreement to mandate this behavior and document it.

  6. Versioning & Compatibility Concerns

  • Discussion about how to communicate these incremental changes to host developers.

  • Agreed to use detailed release notes and maintain versioned header files.

  7. C++ Utility Library Discussion

  • Gary asked if C++20 could be used for new helper utilities.

  • Most attendees are currently on C++17 (VFX Reference Platform).

  • Consensus to target C++17 for broader compatibility.

  • Discussed std::span and potential wrapper strategies.

  8. External Issue: Tile Rendering (Ticket 177)

  • Raised by a Foundry developer.

  • Group agreed on importance of addressing external issues promptly.

  • Action to follow up on documentation and host support suite changes.

Action Items

• JP to add example mappings from OCIO to OFX Basic in headers or doc.

• Phil to ensure instanceChanged is called post-clip-connection in FilmLight.

• Gary to maintain C++17 compatibility for new utility code.

• All to ensure release notes track small incremental spec changes.

• Follow-up on Ticket #177 (tiles) to clarify required behavior/documentation.
