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 in Drama Production
Drama productions
Soap opera’s, quality prime time, motion pictures, …

Metadata in Drama Production
Lots of metadata from start of
production unstructured
metadataon paper synopsis scenario

Metadata in Drama Production
Use the screenplay!
turn into electronic andstructured/processable formats episode/scene/characters describes the
semantics of the product use as base for further production
Scene: INT – TER SMISSE - DAG
Character: Jenny
Character: Waldek
Episode 1004
WALDEK:“Hello Jenny!”
JENNY:“How are you?!”
WALDEK WAVES

Even more metadata…
A lot of implicit‘shooting script’metadata alsofloats around!

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?
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!
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 animationson a timeline
describe specificshooting instructions
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
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

Scene 4: INT – TER SMISSE - DAG
Episode 1004
“Excellent Take!”
“Close-up Jenny”

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
14
Computer Aided Repurposing (CAR)
Automated Repurposing of Drama Different output channels
HDTVSDTV iPod/Cellular
We wish to create optimal products for each platform requires semantically sensible scaling/cropping
15
Repurposing: Output Channels
HDTV Originally acquired
high definition material
SDTV Legacy applications Common pan/scan Editing
(AVID)
Mobile (iPod) Semantically
repurposed
16
Repurposing: How?
1) Determine where the semantic elements are Semantic
Objects of Interestwere defined in thescene model in previz.

Repurposing: How?
2) Provide reframing instructions, e.g.: Object Orientation and Range
“The Bad must be shown on the right…”
Object Size “… and I want it to be a full shot of The Bad.”
0.75
Frame Size Object of InterestSize: (30%, 90%)

Conclusions
Metadata is much more than just‘data about media objects’
Extensive metadata modeling provides significantadvantages 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
