The USC Shoah Foundation Institute has completed a multiyear, multimillion-dollar project to digitally preserve the video interviews in its Visual History Archive. The archive contains testimony from nearly 52,000 Holocaust survivors and other witnesses.
The Institute recorded the testimonies on 235,005 Betacam SP videotapes between 1994 and 1999. All physical media-storage formats experience data rot at some point in time; conservative estimates give shelf lives of 50 years for film, 20 years for videotape, and five years for hard drives before visual content shows signs of age-related damage. In 2008, with funding from the USC Office of the Provost and Oracle, the Institute began processing the tapes to generate copies in a digital format called Motion JPEG 2000, which captures the picture and sound quality of the master recordings.
“The advantage of a digital archive is that we can constantly monitor for data rot and make corrections as soon as any errors are detected,” said Sam Gustman, the Institute’s Chief Technology Officer. “We now have multiple digital copies of the archive at the University of Southern California, and we’ve mirrored an additional copy to a ‘cloud’ storage provider outside California’s earthquake zone. Our goal for digital preservation is to make certain that the testimonies will be available in perpetuity.”
In addition to generating Motion JPEG 2000 duplicates of the testimonies for preservation, the Institute generated other copies in commonly used formats such as MPEG, QuickTime, Flash, and Windows Media Player so that more people can access the Visual History Archive. Digitization has also led to the development of IWitness, an online resource that allows teachers and students 13 and older to interact with more than 1,000 testimonies. Now in beta, IWitness offers a variety of ways to integrate Holocaust-survivor testimony into curricula; teachers can use video clips for classroom lessons or develop their own activities, and students can use IWitness for homework. It can even be incorporated into a semester-long learning experience that involves classroom activities and student-authored video projects. The American Association of School Librarians has named IWitness one of the 2012 Top 25 Websites for Teaching and Learning.
