Re: [AV Media Matters] SVHS Correction & Preservation
DVDs/DVD-Rs are great for access and distribution but not for archiving
legacy archival material.
One archival issue with DVDs/DVD-Rs is that heavy compression is used
compression has two potential problems. One is the loss of the detailed
information like fluffy clouds, fine hair, grass, etc and archival
should never be degraded. The other potential problem with compression
whether or not compression artifacts will show up in the future when the
is copied to a newer format.
The second archival issue is how stable the medium is. At this time, I
only Mitsui Gold.
The third archival issue is interchange. Will your DVD-Rs play on all
of DVD players? Our evidence with CD-Rs is that the answer is no and
density of DVDs is much greater than CDs.
