Preserve Audiovisual Materials

Keywords: Preserve

Activity Definition(s)

Multimedia materials of various types may need to be stored and preserved.  These may be relatively simple objects like a single image or set of images, a sound recording, a video recording, and the like.  These also may be compound objects composed of a number of simple objects, with complex relationships among the components; an example would be a rich multimedia web site, or an electronic journal article.  Each object in a set of simple objects, and each component of a compound object, may have its own set of metadata (for example, data about the media type of each object), as may the set or the compound object itself.  Finally, relationship data may also need to be captured to allow preservation of the rich structure of a compound object.

  • Determine scope of preservation - is it only the overall set or compound object and its metadata (treating the entire object as a complex "black box" bitstream), or is it all individual component objects and their metadata, and the relationships associated with them?
  • Identify the necessary components to be captured and how to capture them.
  • Obtain copies of all the necessary components.
    • Overall metadata for the set or compound object
    • Component digital objects and associated metadata
    • Relationship metadata as appropriate
    • Is there need for identification of the software used in generating the objects, if the media formats are non-standard?
  • Perform any media or format conversion as needed.
  • Establish the intellectual-property rights situation over the various objects, if necessary.
  • Obtain any necessary third-party permissions.
  • If appropriate, assemble, edit and verify the components to insure the resultant set or compound object is properly recreated.
  • Migrate components to more durable formats as needed.
  • Preserve materials in a digital storage facility.

Notes, comments, related activities, concerns

Note:  this activity definition was merged from three original candidates:

  • Store audio recordings
  • Store video recordings
  • Store images.

Video presents special challenges, as it consumes astounding amounts of disk space when uncompressed. Under most circumstances, high-quality, lossless formats are preferred for preservation; for video, however, space constraints can make such preservation impractical.

The New Jersey Digital Highway presents a set of suggested quality standards and appropriate formats for image, audio, and video preservation.
