Video and Moving Image Objects http://odin.page2pixel.org/standards/latest/RUcoreStandards-Video.pdf RUcore Media Standards Working Group: RUcore and NJDH Standards Analysis for Moving Image Objects I. Beard, I. Bogus, E. Gorder, N. Gonzaga, B. Nahory, R. Sandler Version 4 – Last Reviewed 9 August 2010 Last update: 8/9/2010 Progressive download standard for older objects Prior to September 2010, the standard for progressive-‐download presentations videos were as follows, but has since been deprecated with the use of the single-‐source MP4 spec listed above: • If permissions permit: one progressive-‐download video clip o Flash Video Format (.FLV), using ON2VP6 Codec o For 4:3 – Minimum of 640 x 480 resolution (square pixels), 30 frames per second, multi-‐pass encoding o For 16:9 -‐ Minimum of 854 x 480 resolution (square pixels), 30 frames per second, multi-‐pass encoding o Data rate of 512 kbps o Key frames inserted every 30 frames. This rate should be adjusted when necessary. Our experimentation has shown these output settings to be an ideal compromise, producing a clip viewable at acceptable quality on a computer screen while providing a reasonably manageable file size. Users choosing to view this format will need to download the latest version of a free Macromedia Flash Plug-‐in, provided by Adobe Systems, Inc.

Label bands or dedicated storage boxes with labels are preferred. Avoid directly labeling the media if possible. ● If there is an unavoidable delay in transferring the data to the secure network storage, a record for the data will be added to the electronic media transfer queue so that the need for the transfer is documented and attended to in a timely manner. ● RBMSCL/UA transfer drives (used by archivists visiting the donor): Shall be clearly labeled Used only by permission of the Electronic Records Archivist Shall be cleared only after transfer to ITS secure network storage has been verified and then only by the Electronic Records Archivist Archivists shall request the donor NOT purge copied files until transfer has been verified Seth Shaw — last modified Jul 20, 2011 04:13 PM
