| Since early 2004, Media Matters has
been working closely with the Dance Heritage Coalition,
a national non-profit cultural heritage organization
comprised of the United States’ nine largest
repositories for dance and dance-related archival
audiovisual assets. In June of 2004, the DHC released
a report written by Media Matters called the Digital
Video Preservation Reformatting Project. The project
commissioned by the DHC and funded by the Mellon
Foundation sought to determine an appropriate set
of technologies to use for the digital reformatting
of new and aging dance footage. Media Matters investigated
several existing and emerging technologies and recommended
the use of Motion JPEG2000 (MJPEG2K), a relatively
new standard used for the creation of lossy and
lossless digital versions of video. Specifically,
Media Matters recommended using MJPEG2K for lossless
compression as an archival audiovisual format. Further,
Media Matters recommended the use of the Materials
eXchange Format, or MXF, as a “wrapper format”
which has the ability to contain both essence files
(encoded in MJPEG2K) and metadata (in an XML format).
Included in Media Matters’ study were comparisons
of several established lossy standards and other
wrapper formats, such as AAF. |
