4. BUT what about digital
Archiving ?
With a lot more front-end origination and
intermediate workflow occurring in a digital
domain does it not make sense to store and
archive digitally?

5. Digital ARCHIVING
definition:
To copy files to a long term storage medium for
back-up… (webopedia)

7. Positive Factors influencing Digital Storage

8. " Holographic Storage
• Holographic Versatile Disk (HVD),
InPhase Tapestry Media
• Much higher storage capacity per disk
(10x-100x) compared to BluRay and
high data rates (100MB – 1GB/sec)

9. The Digital Dilemma
…We need to understand and
accept that preserving digital motion
picture material is fundamentally
different than preserving film…

11. Problems affecting digital Archiving
While media is progressive and some
claim to be stable for 30-50 years the
question is whether the format
becomes obsolete and more
importantly will there be readers
available in the future?

14. The Digital Dilemma – Industry needs
…A digital archival system must at least be as capable as
the film preservation system it replaces…

15. Digital Archiving - COST
Digital assets can be archived by redundant replicas of the
original assets themselves….but what does this cost?
“…The total cost of ownership should include the cost of data replication…”
Digital storage
costs 10x higher
than film

22. Film as an archival medium
" It is hard to beat film, particularly B&W separations (life
expectancy of silver Image)
" Color films are inherently less stable but have shown
steady improvements in dye stability.
• Digital reconstruction of faded images has demonstrated high
effectiveness
§ Understanding what the film
should look like allows us to
formulate algorithms to re-build
the original image

28. Summary :
The future of archiving
" It will remain a dilemma
" hybrid solutions will evolve…
• Digital for short term, easy access
• Film remains the best for long term archival
