Art & Media - Media Production Scenario
Commissioning to Preservation Ingest and Re-use
Tate has its own media production unit, Tate Media, which produces a large volume of audio-visual content. This content aims to increase access to Tate’s collection and exhibitions, and contributes to Tate’s core mission of increasing public understanding and enjoyment of British, modern and contemporary art. The content is published online via the Tate Channel: http://www.tate.org.uk/context-comment/audio-video

Media Production presents a number of issues that are of interest to PERICLES researchers relating to the preservation and re-use of material. It is a rapid working environment so it is particularly important to have systems in place that seamlessly integrate with workflow and incorporate automated processes wherever possible. The re-use of media content is reliant on the capture of full descriptive and semantic metadata and the management of this metadata throughout the content life-cycle. Recording rich metadata about the visual content of media will allow for improved searching of content and ensure greater re-use of material now and in the future.
The scenario created for Media Production describes an ideal process for the creation and management of digital files and associated metadata. This process encompasses the following stages:
Commissioning - initiation of project and generation of a project ID.
Pre-Production - establishment of project details, setup of file structure in Media Asset Management System.
Production - capture of audio and video and specified metadata, back-up of files and quality control checks.
Post-Production Ingest - transfer of raw files to asset management system, preparation for editing, extraction of metadata.
Cataloguing - addition of descriptive metadata.
Editing - management of editing process, including version control.
Exports - project signed off, transcription and extraction of semantic metadata, consolidation of project files.
Publishing and Delivery - delivery of product to access platforms.
Preservation pre-ingest - preparation of files for ingest.
Preservation ingest - processing of files, creation of Archival Information Packages, and transfer to archival storage.
An additional re-use scenario then describes an example of future re-use of media content, utilising metadata created and managed throughout its active life. Media segments are often re-used for new purposes and given new meaning. This raises questions about how re-use changes the context of media over time, and how re-use is recorded.
Tate Media have provided sample data and worked with CERTH on extracting information on visual content. This has contributed to the first iteration of the VERGE tool, which allows searching of media footage for visual elements such as people, objects and buildings. Tate Media will continue to work with PERICLES technical partners on testing new workflows and exploring the impact of change on re-use of media.
