TX Joshua…

 

Quick note about:

 

- Autodesk Flame team has some AAF expertise. Michel will reach out to them to see if they can share any insight/advice.

 

As discussed, if you can provide me with a list of open questions regarding AAF, this would help me getting the information more rapidly.

 

TX,

 

Michel.

Here are my notes from today's TSC meeting.

 

Attendees:

Joshua Minor (Pixar)

Robyn Rindge (Pixar)

Eric Reinecke (Netflix)

John Mertic (Linux Foundation)

Michel Eid (Autodesk)

Josh Burnell (Dreamworks)

Sean Wallitsch (Dreamworks)

 

Next steps in ASWF process

- Meeting with Pixar legal and Linux Foundation legal scheduled for next week.

Topics: Switching to unmodified license, switching to minimal CLA, TSC charter, trademark transfer.

- License scan waiting until after license switch.

- OTIO website - we can talk with Emily Olin when we're ready for this.

 

Summary & discussion of current OTIO roadmap

- We are using Github's Project page to organize our near-term roadmap

- Main directions include: C++ API, Schema enhancements, AAF adapter, Integration with more 3rd party software

 

C++ API

- C++ port was landed in master right after last release (beta 11)

- Pixar is nearly done integrating OTIO C++ into our in-house animation system, Presto.

- Autodesk provided feedback during development, but waiting until there are new features before switching from their in-house implementation.

- Looking for others to test & file bugs & feedback.

- Next release (beta 12) will include C++ core (and some stability improvements related AAF support)

- Some folks have noticed friction when updating to the latest (e.g. pip install's -e option doesn't work).

- Please file bugs & fixes to improve these quality of life issues, they will pay off when we do the next release :)

 

AAF

- Aiming for more robust AAF support.

- Working well for Pixar pipeline, but we have a lot of consistency in our media & compositions. Others finding issues.

- Some bugs are only repeatable with AAF files that cannot be shared publicly.

- Some technical documents provided by Avid are not approved for sharing publicly.

- Continuing discussion with Avid about this.

- Autodesk Flame team has some AAF expertise. Michel will reach out to them to see if they can share any insight/advice.

- Dreamworks working to switch to using OTIO AAF adapter. Seems to be going well.

- OTIO is missing a How-To document that explains how to use AAF in a pipeline.

 

RV

- Autodesk has native OTIO support on their long term roadmap.

- For near-term Autodesk is committed to more engagement in discussion.

- OTIO plans to land the WIP OTIO RV plugin, aiming development towards the RV plugin rather than the RV adapter.

 

Schema

- Two types of schema improvements on the roadmap: new features & revisions to existing schema.

- Revisions are mainly:

Switching to integers instead of doubles for RationalTime

Revising the time composition model & API to better support time warps, transitions, and queries up/down the composition hierarchy

- Additions include a wide range of new features

Examples: Subtitles, Still Images, Image Sequences, Annotations, etc.

- Priority of these will be driven by community use cases - which ones do you need/want?

- Also heavily influenced by who is willing to do the work.

- Schema changes should be queued up so we don't change too many things at once.

- Integer-based RationalTime is likely to be first.

- Autodesk proposes a universal coordinate system for spatial attributes - especially media size/resolution and compositing effects.

- At some future TSC meeting Autodesk will teach us more about this proposal.

- Netflix is interested in helping to formalize the OTIO spec.

- Eric is now the point person for this. We expect more discussion after some upcoming vacation.

 

OTIO View

- This is listed on the roadmap project page, but not in active development.

- Volunteers are welcome to work on this :)

 

3rd Party Integrations

- Media Composer AAF support, and RV support mentioned earlier.

- There is some talk about Nuke Studio & Flix OTIO support - looking for contact/interest from Foundry.

- If there is an app or format that you want to have better OTIO support, please file an issue, or help us make contacts.

 

Let me know if I missed anything important, or if you have questions about any of this.
