Agenda
- Welcome/Intros
- WG chair not present?
- There was a schedule conflict, but the meeting didn’t get moved.
- Calendar issues form some folks.
- Future meetings should be advertised on the mailing list and/or Slack?
- Other ASWF WG meeting earlier today had similar problems.
- Scope of Working Group
- Aiming to create a proposal to ASWF
- Question: Is this WG aiming for just current ASWF project-related assets, or something larger than this? For example, challenging scenes to render.
- Homework followup:
- Does your company have assets that would be useful to share?
- Disney Animation findings (via Rob Bredow & Nick Cannon)
- Relaying message from Nick Cannon
- Getting permission for the Moana Island project was actually easier than expected. Disney’s openness for this could set a positive precedent.
- Took a long time to get approval, but actual legal work was quick.
- Biggest cost was in labor involved in transforming the data into an open format. OBJ - For example, USD version of Moana Island is still in progress.
- Hosting cost for large data sets was non-trivial, but not super expensive (just needs to be budgeted)
- Licensing questions: will the content be misused in a way the creators/owners are uncomfortable with?
- Cannot use Disney trademarks, cannot misrepresent derivatives as coming from Disney
- Short paper about the challenges: https://www.disneyanimation.com/publications/?drawer=/publications/the-challenges-of-releasing-the-moana-island-scene/
- OpenTimelineIO findings so far (JT + Josh)
- JT Nelson has collected open film content here: https://docs.google.com/document/d/1_kefZpDT98-TSWlEN9X3IdLJGNbq0F4w-kKilyw2jkg/edit
- We have found the source assets, and final footage for several open films, but we have not yet found the actual editorial timeline for any of these yet.
- Licenses?
- Hard to get “real production” assets.
- Moana Island license allows for “research and software development” - we would want more permissive allowances for presentations, demos, etc.
- Do we know stories/use cases where terms were too restrictive?
- Some content out there is published without a clearly identified license. For example, these video clips and source assets say “Creative Commons” but without specifying which CC license: https://www.beeple-crap.com/vjloops
- Desired uses:
- Research
- Software Development
- Performance Testing
- Correctness Testing
- Presentations & Demonstrations
- Example open assets:
- Moana Island scene: https://www.disneyanimation.com/data-sets/?drawer=/resources/moana-island-scene/
- Hyperspace Madness: https://area.autodesk.com/hyperspacemadness/
- USD sample assets: http://graphics.pixar.com/usd/downloads.html
- Sony Zombie Rig: https://secure.sonypictures.com/animation/hotelt/zombierig/videosubmissions/
- Netflix open media: https://netflixtechblog.com/engineers-making-movies-aka-open-source-test-content-f21363ea3781
- Blender Foundation projects (Blender scene files + rendered clips):
- More here: https://docs.google.com/document/d/1_kefZpDT98-TSWlEN9X3IdLJGNbq0F4w-kKilyw2jkg/edit
- Possible assets that could be contributed
- From animation studios, VFX, etc.?
- From Universities?
- UCLA Film and Television Archive
- AWS has some assets that might be a good choice (Haley Kannall)
- Imageworks (Emoji city “Textopolis”, and a realistic dog)
- Light transport test scenes from Intel (Sebastian Herholz)
- Cloud (weather kind of cloud) asset library for OpenVBD from Intel? (Sean McDuffee)
- Hosting costs
- Some potential contributors are concerned about cost of hosting
- ASWF could possibly host these - this WG will attempt to estimate size and costs for proposal to ASWF TAC & Governing Board
- Moana data set is 265 GB (46 GB compressed). Hosting cost was 70 TB in the first week of downloads (tapered off from there).
- Note: we should pick assets that appeal to the desired audience and not accidentally induce high hosting costs (e.g. a high profile, famous character or location might be a poor choice?)
Action Items:
- Locate assets at your company/project that might be worth contributing.
- Ask your employer about contributing - what are their objections, how could ASWF lower the barriers to entry?
- Estimate size of assets.
