Indiana University. Department of Radio and Television
The Indiana School of the Sky radio program of the Indiana University Department of Radio and Television began broadcasting educational radio programs in 1947 and continued through the early 1960s. The program reached schools throughout Indiana and nearby states and led to new course offerings at IU. Indiana University students performed in the radio programs originally intended for children ages 4-8 aired for 15 minutes during each school day. Eventually the popularity of the programs called for high school programming as well, and later adults also tuned into the programs. This collection contains recordings of these programs.
The MDPI project posed a tremendous technical challenge: digitize and process around 280,000 audio and video assets by the University’s bicentennial. The first objects began processing in June 2015 and by the summer of 2016, the major problems had been worked out and the processing was proceeding smoothly.
Then the discussions of film processing began.
In theory, processing film is the same as audio and video. On paper, it seems easier: even though the time allotted is less than A/V, there are only 25,000 reels to process.
In reality, however, it is a very different beast. An hour of film scanned at 2K resolution is 20x larger than an hour of video. When a film is scanned at 4K, it is 80x larger than video. Additionally, the film preservation master consists of not just a few files, like we see in audio or video, but thousands of files: a picture for every frame. Like all preservation masters, these files must be validated.
This session will address the challenges and solutions that were needed for the back end processing to be able to process film efficiently.
"Metadata is a love note to the future" mused Jason Scott, archivist for the Internet Archive. Librarians and archivists cultivate metadata standards and practices to shape the future of resource description...so what does the metadata in our past say to us now? And what do our standards and decisions say to our descendants? IU’s Media Digitization and Preservation Initiative (MDPI) and new Avalon-based Media Collections Online (MCO) have brought to light both issues and opportunities related to metadata creation and upkeep, impacting how we view our legacy data and how we create new data. The decisions and projects intended to improve and enrich this vast repository will be discussed, as well as suggestions for other institutions interested in taking on similar projects.
The process of converting the digitized MDPI media into something that can be used for web delivery is conceptually simple: transcode each one into derivatives and transfer them to the delivery system. However, like most things, the devil is in the details. Data corruption, tape latency, and managing large amounts of data are just a few of the problems which must be overcome.
This session will follow the steps that MDPI digital objects take during processing and explore the solutions used to create a system which must reliably process hundreds of hours of audio and video content daily.
