Background and Technical Processes for the VIVA Multimedia Collections Task
Force
Jeff Clark, Grover SaundersJames 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 ProcessThe Process
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
MPEG-4 chosen as archive format to facilitate ease of future encoding.
This is the most time consuming aspect of the process mostly due to
dead time between DVDs.
The EncodingArchives 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 automaticallyprocess 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 audio
Archive - 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
• 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.
Upload files to the server
Updates to catalogs made from spreadsheet
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.
