Future Agenda Items:

• See the Agenda github project page at https://github.com/orgs/AcademySoftwareFoundation/projects/26/views/1

Meeting called to order at 12:01pm EDT.

• None

• Meeting commenced informally as participants joined.

• Special welcome to Artur Pawlak (Maxon), who introduced himself as a software development manager and described recent interest in “scene lights” and camera support.

• Phil Barrett reported FilmLight is preparing a new release with OpenFX improvements, including color properties and spatial awareness features.

  • Testing involved 3rd-party users: Invisigrain, Filmbox, Live Grain, and some of Pierre Jasmin’s plugins.

• Gary offered to help publicize the release through ASWF or the OpenFX website.

• Discussion about standardizing how hosts/plugins identify thumbnail renders.

  • FilmLight and others have long used a Thumbnail property, but it has never been formally standardized.

  • Agreed Phil will draft a proposal describing the current approach for consideration as an OpenFX standard.

  • Discussion included use cases, possible adoption by other hosts, and distinctions between thumbnail render and other low-res or scaled rendering.

• Paul Miller updated on interpolation: new code is ready for review/testing (Pierre Jasmin to test), and there is ongoing work to extend standard properties for clip/image metadata.

  • Discussion about how to coordinate standard property definitions and how to handle host-defined properties.

  • Gary and Paul to collaborate further on property metadata format and implementation.

• Gary, JP, and Paul discussed support for ARM64 and ARM64EC plugins on Windows.

  • A known issue: X64 hosts on ARM hardware do not automatically find ARM64EC plugins unless a shim or redirector DLL is provided.

  • Consensus: Document this as a known limitation; recommend vendor-specific solutions (such as a loader shim) but not standardize a solution until an open-source shim is available.

  • Related technical challenges with building and packaging dependencies (e.g., OpenCV, OpenEXR) for multiple architectures discussed.

• Gary described an issue where Resolve/Fusion does not send an “instance changed” notification after project reload, resulting in plugins not knowing when input connections change.

  • Discussion on how to handle this in the spec.

  • Consensus: Saving and reloading should be treated as recreating what the user did, so a notification should be sent.

  • Action: Gary to follow up with Resolve developers and update the PR/spec as needed.

• Gary is developing a new property checker tool and C++ helper library, using a YAML-based source of truth for property definitions.

  • This enables auto-generating documentation and more type-safe property access in plugins.

  • Work is ongoing; Gary invited others to review and contribute.

  • Paul mentioned similar lightweight wrappers for parameters/properties.

• Several outstanding PRs (notably from Pierre Jasmin) were discussed.

  • Pierre to review and determine next steps for his older PRs (e.g., GPU utility, color space proposals).

  • Agreed that old PRs should either be advanced, closed, or moved to draft if not ready for review.

• Gary reminded everyone to report documentation issues in spec comments or PRs. The spec’s header file comments are considered canonical.

• Artur Pawlak (Maxon) raised interest in standardizing scene lights and camera lists.

  • Gary explained the typical process: add as a GitHub issue with “standard change” tag, develop a proposal collaboratively, test with host and plugin vendors, and submit for group approval.

• Artur will add agenda items for future discussion.

• Proposal to move the July meeting from July 1 (Canada holiday and Gary traveling) to July 8.

  • Some schedule conflicts noted; final decision to be made via Slack poll.

• No further business.

• Meeting adjourned until next month.

Actions/Follow-ups:

• Phil Barrett: Draft PR on thumbnail property standardization.

• Gary & Paul: Collaborate on property metadata and C++ library.

• Pierre Jasmin: Review older PRs, decide next steps.

• Gary: Update PR/spec for instance changed; Slack poll on next meeting date.

Meeting adjourned at 12:55pm EDT
