Digitization

  • Currently: 15500+ ads digitized.
    • Some as early as 1950's, a majority from 1980's and on
    • Originals were VHS recorded from TV
    • iMovie used to capture, with a Canopus DAC box
    • .dv files for masters
        • Pros:
      • easy
      • good for editing/sampling
        Cons:
      • lossy
      • future as a format?
    • H.264 .mp4 files for web playback (used to use quicktime, moving to flash)

Storage

  • Files occupy 1.5 TB on a 3.5 TB Apple Raid array
  • Filenames identify company and year.
  • Initially metadata was stored in a Filemaker Pro DB, and 2400 coded ads were presented through a web interface.
  • Currently developing the next version of the database, with a web interface to allow for more distributed coding

Metadata/Annotation

  • We've found limited options for simple, local, integrated media annotation
  • Recently begun using Frameline 47, which allows for saving mpeg 7 metadata in video file
    • Integrated, so movie clip plays next to annotation fields
    • Automatic Scene Detection
    • Segemented annotation
    • SQLite storage
    • Multiple format export, inc. XML
  • Mix of controlled vocabulary and open freeform tagging for simple sections
  • Full transcription of vioceover and textual data
