§ 1
The Digital Dilemma Report by Council of Science and Technology for the Academy of Motion Picture Arts and Sciences
§ Thierry Perronnet § EAMER MARKETING DIRECTOR
§ 2
ARCHIVING
definition:
“…a collection of material protected and stored for future value or interest…”
§ 3
Film Archiving " Preservation of the Original Camera Negative (OCN)
OR " Preservation of a Color Separation Master (YMC’s)
§ 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)
§ 6
What is the right storage media ?
§ 7
Positive Factors influencing Digital Storage

Cost of data 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…”
2007 Report prepared by the Science and Technology Council of the Academy of Motion Picture Arts and Sciences

Problems affecting Digital Archiving
§ 11
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?

“The Digital Dilemma – Industry needs
“…A digital archival system must at least be as capable as the film preservation system it replaces…”
2007 Report prepared by the Science and Technology Council of the Academy of Motion Picture Arts and Sciences
§ 15
“Digital Archiving - COST
Digital assets can be archived by redundant replicas of the original assets themselves….but what does this cost?
2007 Report prepared by the Science and Technology Council of the Academy of Motion Picture Arts and Sciences
Digital storage costs 10x higher than film
“…The total cost of ownership should include the cost of data replication…”

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

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
