Film Restoration & Preservation
• Of course this requires scientific processes including: – Chemistry (for analog restoration & preservation) – Computer skills(for digital restoration and preservation)
• But this also requires important non-scientific processes: – Curatorial (historical research, contextualization) – Collection management (record-keeping, tracking,
planning)

• Examples of Collections & Problems • Digital Works • 4 Distinct Digital uses • What is reformatting? • Scientific approaches to reformatting • Why we need more than science

Digital Works
• Can be – “born digital” (recorded with a digital
camera, edited on a digital editor), or – “Digitized” from Analog works (film), or – “Hybrid” (combining “Born digital” elements
with “Digitized” elements, or Digitizing as an intermediate step between original film and new film master
Besser-Cineteca Mexicana, 27/7/09
Most Common Digital Sizes
• For ReFormatting (TeleCines) and Display (Projection) – 2K (2048×1080) – 4K (4096×2160)
• Most cameras today are roughly 2K, as are most projectors
• Laboratories are often equipped with variable-size reformatting specifically for intermediates
Besser-Cineteca Mexicana, 27/7/09
4 distinct Digital Uses-
• Digital Restoration • Digital Projection • Digital Preservation • Digital Access
Besser-Cineteca Mexicana, 27/7/09
Digital Restoration
• Use digital or hybrid techniques, and end-product can be output to film or digital form
Digital Restoration output to film is the most widely used today
Besser-Cineteca Mexicana, 27/7/09
Digital Projection • Use DCI-compliant projectors to show films in digital
form • But projectors are really made for contemporary
Hollywood films, so they may cause deep problems for the Film Archive world: – Only support 24 and 48 fps – Fixed Aspect Ratios, meaning that Scope prints must use less
pixels (currently being addressed) – Built-in security, matching cinema content to a projector number
• FIAF has been trying to influence the SMPTE standard
Besser-Cineteca Mexicana, 27/7/09
Digital Preservation-
• Expensive & requires large set of skills • Requires a very large infrastructure to
maintain
Besser-Cineteca Mexicana, 27/7/09

Besser-Cineteca Mexicana, 27/7/09
Digital Preservation
• Requires new file formats and new physical strata at regular intervals
• Needs a serious Managed Environment • Requires staff with knowledge of
computer storage, metadata, migration strategies, obsolescence issues, as well as curatorial

What is reformatting?
Besser-Cineteca Mexicana, 27/7/09 Besser-Cineteca Mexicana, 27/7/09
Difficult Materials become obsolete relatively quickly
• The physical carriers decay or become obsolete
• The technology required to view the carriers changes frequently
• The encoding formats needed to decode the content shift

We can’t keep all the equipment for all film formats
• Nitrate • 8mm • Super 8 • Cinemascope • 55mm-

Why do we Reformat? • Because we cannot sustain the original object (its
physical characteristics are deteriorating too fast) • Because continued access and handling of the
original object will rapidly decay its physical characteristics (so we create a surrogate for users and store the original in very good conditions, away from users)
• Because viewing the work requires some kind of technology, and we can’t keep that technology working very far into the future-

Limitations of Reformatting
• Authenticity issues (more later) • User behaviors (newspaper, book,
video game, …) • Users mistaking the reformatted work
for the original
9
Besser-Cineteca Mexicana, 27/7/09
Critiques of Reformatting
Mainly User Behaviors
• Can’t view outside the library
• Only sequential access
• Viewing and studying is awkward
• … Besser-Cineteca Mexicana, 27/7/09
But unless we Reformat, we totally lose some kinds of works
(particularly audiovisual works like film) • 50% of all titles produced before 1950 have vanished
(approximate number as of late 1970s) • This reflects full-length features; survival rates are much lower
for other types (studio newsreels, shorts, docs, independent, …), and these “orphans” are particularly in peril
• Fewer than 20% of features from 1920s survive in complete form; survival rates of 1910s is <10% (& none of these are negatives)

Why we need more than only science
Besser-Cineteca Mexicana, 27/7/09 Besser-Cineteca Mexicana, 27/7/09
Commercial Reformatting Issues: PR at 1967 re-issue of GWTW • “Spherical Blow-Up” • “In the Splendor of 70mm. Wide screen and full
stereophonic sound!” • “For the thousands who remember its unparalleled
drama, action and romance! For the new thousands to whom the wonders will be revealed for the first time! Breathtaking spectacle, inspired acting by the greatest cast ever assembled! The screen's most exciting love story! The most-talked about picture ever made!”
• http://www.imdb.com/title/tt0031381/taglines
Besser-Cineteca Mexicana, 27/7/09
But most people didn’t know that 70mm widescreen is different shape than 35mm normal

Pan and Scan example
• 7 Brides for 7 Brothers, Stanley Donen, MGM, 1954 from http://en.wikipedia.org/wiki/Pan_and_scan
Besser-Cineteca Mexicana, 27/7/09
This meant eliminating part of the frame
Besser-Cineteca Mexicana, 27/7/09
Eliminating even in famous scenes
Besser-Cineteca Mexicana, 27/7/09
But the re-release wasn’t governed by artistic concerns
• Intellectual Property is owned by MGM, not by Fleming or Selznick
• MGM is motivated maximizing profit, not in maintaining artistic integrity
• Bigger is always better
• Not radically different than another blow to artistic integrity/originality in Atlanta 20 years later…
Besser-Cineteca Mexicana, 27/7/09
Atlanta was also home of 1980s Colorization movement

Sometimes even the Director wants to go back and change their original film

Besser-Cineteca Mexicana, 27/7/09
Someone needs to maintain the integrity of artistic works
• This means preserving original versions – even when commercial interests want to
replace the older version with something new and fancy
– even when the “artist” wants to use more recent technological developments to “improve” their work
Besser-Cineteca Mexicana, 27/7/09
Film & other Media Archivists
• Preserve original works • Provide access to older versions • Maintain the integrity of the “original” in any
restoration process • Champion works that do not have commercial
entities pushing for their preservation and distribution
• Try to make sure that works are viewed within their original context-

Clip #2 Ernst Fredrik Werner Alexanderson
in the General Electric “House of Magic” • “We have succeeded to
photograph the television image on a moving picture film. Important events that in the future may be intercepted by the television camera and broadcast to all corners of the world may thus be recorded on the film and kept in readiness in moving picture houses for projection of a lifetime some minutes or hours after the event.”
• Cuts to close-shot: “We hope that this will be one
more step to widen our horizon and to make all people our neighbors.”

Possible endless need for reformatting implies
• Possible loss with each generation • Requires managed environment • Can lead to © violations-
Besser-Cineteca Mexicana, 27/7/09
Managed Environment
• More than temperature & humidity control
• Periodic monitoring of the works • Periodic monitoring of the technical
environment for viewing the works (software, systems, hardware)
• Trusted repositories
Besser-Cineteca Mexicana, 27/7/09
Storage Media
• Removable media (like CDs) is not a long-term answer
• The long-term answer requires ongoing management, and involves regular migration or emulation. This solution is only viable with storage on spinning disks-

Besser-Cineteca Mexicana, 27/7/09
Storing on CDs becomes a big problem over time
Besser-Cineteca Mexicana, 27/7/09
Consumers replace their CDs with a hard disk (& so should archives)
Besser-Cineteca Mexicana, 27/7/09
Plain DVDs are no longer the latest format
Besser-Cineteca Mexicana, 27/7/09
So, with electronic works, the focus should be less on stable temperature

Your Challenges as an Archivist
• You are custodians of our Heritage • You need to make sure that that Heritage
endures (preservation) • You need to make sure that that heritage can
be used for research, education, etc. (access) • We live in a media-saturated era, and new
media works pose continuing challenges for us
Film Restoration & Preservation
• Of course this requires scientific processes including: – Chemistry (for analog restoration & preservation) – Computer skills(for digital restoration and preservation)
• But this also requires important non-scientific processes: – Curatorial (historical research, contextualization) – Collection management (record-keeping, tracking,
planning)
