JMU Online Video Collection • Background and Technical Processes for the VIVA Multimedia Collections Task Force • Jeff Clark, Grover Saunders • James Madison University
JMU Project • GOAL: Provide high-value, high-use online video programming in decent quality for classroom or desktop viewing. • “No more check-out” • Inspired by OhioLINK project.
Project Implementation • Initial task force included all campus technology partners • Library • Media Resources • Classroom Technology • Center for Instructional Technology • Information Technology • Computing Support
Task Force Recommendations • Campus infrastructure adequate • MPEG-4 format • Streaming options for high/low bandwidth • Download option for faculty if possible
Task Force Recommendations • QuickTime player for standard support • User access and authentication through existing Madison Digital Image Database • Add links to library catalog records • Small pilot project first
The Cataloging • DVDs are received from the vendor. • Cataloging info is collected and organized in an Excel spreadsheet • DVDs are sent to CIT for encoding.
The Ripping • DVDs are copied to the hard drive and encoded in groups of ten using Handbrake. • Free & Open Source • Archive quality .mp4 • Archive stored for future revisions to project.
The Ripping This is the most time consuming aspect of the process mostly due to dead time between DVDs. MPEG-4 chosen as archive format to facilitate ease of future encoding.
The Encoding Archives are encodedfor delivery usingSorenson Squeeze • Streaming • 300k for off-campus • 500k for on-campus • Download • VBR suitable for viewing full screen in class
The Encoding “Watch Folder” allows us to automatically process files after they are ripped. MPEG-4 Video with AAC Audio 300k- 480x360, 256k,15fps, 32k audio 500k - 512x384, 512k, 30fps, 64k audioVBR - 512x384, 1Mb, 30fps, 128k audioArchive - 720x480, 2Mb, 30fps, 256k audio
The Ripping & Encoding Hardware • Dual 2.3 Ghz G5 from Apple • Wide range of video tools available for OS X. • Eventually 3 dedicated machines for this task. • Processors and HD space most important criteria for any purchase.
The Cataloging Part II Upload files to the server Updates to catalogs made from spreadsheet • MDID • Restricts access to JMU community and manages rights to individual files. LEO – JMU’s online library catalog. This ties the physical resources with the online version. Promotes service.
The Streaming Server • Apple Xserve with Xraid • Dual 1.8 Ghz G5 • 1.1 TB of storage in RAID 5 • Expandable to 4.6 TB by just adding modules • Chosen for price and ease of administration. • 919 Titles (460GB) and 453 Archives (314GB)
The Viewer • MDID determines access to individual files. • Users must use Quicktime player to view streams. • When vendor allows it, faculty also can choose to download the video ahead of time for in class viewing.
