Metadata to create and collect

  1. 1. Metadata to create and collect “Metadata bij de omroep” December, 3rd 2008 Dieter Van Rijsselbergen Universiteit Gent – IBBT Multimedia Lab
  2. 2. Metadata?  Metadata can be much more than just ‘data about media objects’  Instead of organizing metadata around material…  Organize material around a (meta)data model Metadata Metadata Metadata Metadata Metadata Metadata Metadata Metadata Metadata 2
  3. 3. Metadata in Drama Production  Drama productions  Soap opera’s, quality prime time, motion pictures, … 3
  4. 4. Metadata in Drama Production  Lots of metadata  from start of production  unstructured metadata on paper  synopsis  scenario 4
  5. 5. Metadata in Drama Production Episode 1004  Use the screenplay! Scene: INT – TER SMISSE - DAG  turn into electronic and Character: Jenny structured/processable formats Character: Waldek  episode/scene/characters  describes the WALDEK: semantics of the product “Hello Jenny!”  use as base for further production WALDEK WAVES JENNY: “How are you?!” 5
  6. 6. Even more metadata… Metadata…  A lot of implicit ‘shooting script’ metadata also floats around! Metadata… Metadata… 6
  7. 7. Expressing the shooting script: storyboard  How do we express the way in which scenes are ‘shot’?  Legacy technology: storyboard  unfortunately interpretation only by human ‘actors’  what about machines? 7
  8. 8. Expressing the shooting script: animatics  Emerging: animatics or previsualization  for visually complex scenes  Built using off-the-shelf 3-D authoring software  limited computer perception of the scene  but in terms of geometry, translations, …  too much math! too little cinematography! 8
  9. 9. Expressing the shooting script: Scoop  Step further: Scoop 3-D Previsualization  Provide directors, producers, camera operators with tools to express cinematographic vision  add camera’s, microphones  use proper terminology  pan, tilt, dolly, …  prepare dialogue and animations on a timeline  describe specific shooting instructions 9
  10. 10. Model-driven Product Development  Construct a virtual model of the scene  create a blueprint of manufacturing specifications  populate with engineering information  completed with metadata obtained in further production process  centralized repository of metadata 10
  11. 11. Creating and collecting Metadata  What can we do with all this metadata?  Acquisition  controlling and cataloging takes  annotating takes  Editing  rough cutting  automating  Computer Aided Repurposing 11
  12. 12. Acquisition  Acquisition Episode 1004  controlling and Scene 4: INT – TER SMISSE - DAG cataloging takes  annotating takes “Close-up Jenny” Take #2 “Excellent Take!” 12
  13. 13. Editing  Rough cutting: building evolving products  mixture of previsualized and shot footage  evolve from all-previsualized to all-shot composition  Automate editing decisions  Use previz. EDLs and re-apply to real footage 13
  14. 14. Computer Aided Repurposing (CAR)  Automated Repurposing of Drama  Different output channels  HDTV  SDTV  iPod/Cellular  We wish to create optimal products for each platform  requires semantically sensible scaling/cropping 14
  15. 15. Repurposing: Output Channels  HDTV  Originally acquired high definition material  SDTV  Mobile (iPod)  Legacy applications  Semantically repurposed  Common pan/scan  Editing (AVID) 15
  16. 16. Repurposing: How?  1) Determine where the semantic elements are  Semantic Objects of Interest were defined in the scene model in previz. Jenny Waldek 16
  17. 17. Repurposing: How?  2) Provide reframing instructions, e.g.:  Object Orientation and Range  “The Bad must be shown on the right…” 0.75  Object Size  “… and I want it to be a full shot of The Bad.” Frame Size Object of Interest Size: (30%, 90%) 17
  18. 18. Computer Aided Manufacturing: Workflow 18
  19. 19. Workflow (1): Synopsis 19
  20. 20. Workflow (2): Management 20
  21. 21. Workflow (3): 3-D Previz. – Scenario 21
  22. 22. Workflow (4): 3-D Previz. – Shooting Script 22
  23. 23. Workflow (5): 3-D Previz. Editing 23
  24. 24. Workflow (6): Acquisition & Logging 24
  25. 25. Workflow (7): Editing 25
  26. 26. Workflow (8): Quality Assurance & Analysis Plane 26
  27. 27. Workflow (9): Repurposing 27
  28. 28. Workflow (10): Conform & Publish 28
  29. 29. Conclusions  Metadata is much more than just ‘data about media objects’  Extensive metadata modeling provides significant advantages  pursue model-driven product development  better communication: between staff and machines  in acquisition associate audiovisual material easily  in editing, repurposing  ease and automate production tasks  centralize production metadata 29
