"New Progress In Film Preservation" |
|
By
On June 14, 2005, the Hollywood Section
of the Society of Motion Picture and Television Engineers ended its
2004-05 year with the above titled program in the Linwood Dunn Theater
at the Academy of Motion Picture Arts and Sciences' Mary Pickford Center
in Hollywood. Since film preservation became a hot topic in the early
Eighties, the SMPTE has regularly presented programs on this subject.
The evening's co-hosts were Ralph Sargent of Film Technology
Laboratories, one of the foremost firms involved in this work, and
Richard P. May of Warner Bros., who has been overseeing such work with
the MGM and, later, Turner library for twenty years.
Mr. Sargent opened the evening with "Moving Images For The Future," a
short his company had made in 35mm CinemaScope, especially for a 1999
SMPTE Film Conference, which, in the classic "a picture is worth 1,000
words" tradition, illustrated the state-of-the-art processes involved in
film preservation and restoration at that time.
It should be noted here that those two terms are often confused.
Restoration refers to preparing surviving pre-print materials: original
cut camera negatives, fine grains or interpositives or separations for
color films, internegatives, or even release prints for preservation;
repairing tears, replacing missing perforations, filling in missing
material from other sources. Once this is done, new preservation
elements are struck and stored under exacting temperature and climate
conditions. Mr. Sargent reported that properly processed and stored
nitrate film was estimated to have a shelf life of 600 years, polyester
film 1,000 years, but acetate based film only 70 years. Since acetate
has only been used for 35mm for about 54 years, I forgot to ask if that
figure was based on aging tests or the condition of the 16mm, 8mm,
9.5mm, and other small format stocks Mr. Sargent's company has been
successfully blowing up to 35mm in recent years. These have always been
safety stocks and some of the samples Mr. Sargent exhibited at an SMPTE
meeting a few years ago were from sources over 70 years old.
The biggest change cited was the increasing use of digital technology to
deal with problems that couldn't be handled photochemically. Digital
techniques have been used to clean up sound tracks since their
wide-spread introduction into the industry a decade ago, as illustrated
in the film and further described by guest speaker John Polito of Audio
Mechanics, but their application has been fairly limited until recently
due to the combination of cost and the amount of storage and processing
space required to do the work at an acceptable resolution to match 35mm
film.
Disney pioneered this a decade ago using digital techniques to clean up
the original negatives of "Snow White And The Seven Dwarfs" (1937) and
advanced techniques for some of its other films as well as
"Mary
Poppins" (1964) for DVD. Other preservationists have resorted
to it to fix large rips and other defects in individual shots. However,
1 and 2K scans and outputs were considered to be of too low a resolution
for the preservation of an entire 35mm live action feature.
In the last two years Warner Bros. has attracted attention with its
proprietary process of scanning nitrate three-strip Technicolor
negatives and digitally correcting them for shrinkage, which leads to a
much sharper image than is possible photochemically. There has been some
controversy over this because the work so far has been done at 2K, which
is acceptable for video, but those who've seen a film printout of
"Singin' In The Rain," the first film done this way, were not happy with
the result. The contemporary state of this issue was covered in the
clips presented in the second half of the program.

Elizabeth Taylor
In "Suddenly Last Summer" |
First, to illustrate what can still be
done photochemically, four clips were shown from "Suddenly Last Summer"
(Columbia; 1960), courtesy of Grover Crisp of Sony. Damage to frames of
the original negative was corrected by replacing those shots with dupe
negatives of clean versions taken from a fine grain made before release
printing began. This has long been a common technique (see appendix),
with the replacement footage usually quite obvious because of their
higher contrast and increase in grain. These clips illustrated how
modern processing techniques and stocks make such insertions virtually
undetectable; in fact, the last clip used dupe replacement negatives
made 40 years ago.
Barry Allen of Paramount then exhibited two works in progress from films
his company inherited when it was bought by Viacom, which had previously
bought Republic Pictures, nee National Telefilm Associates. One of the
four biggest titles in this package is "Johnny Guitar" (1954), whose
original negative had been deemed no longer printable and junked in the
Sixties, with all subsequent prints struck from a not very well made
internegative from that time. He showed a recent test clip from this
internegative which looked worse in terms of both sharpness and color
than the 16mm print I got through the Nostalgia Merchant 25 years ago.
As seems to have generally been the case back then, the separations made
at the time also had problems, but he decided to borrow a leaf from
Warner Bros. and see what results he could get by scanning and
attempting to reregister them digitally. The results were a great
improvement, though Mr. Allen was not satisfied and plans to do further
work.
He also presented an illustration of how different print stocks can
affect the results with a scene from the original nitrate negative of
John Ford's "Rio Grande" (1950) printed on standard Eastman B&W print
stock and the East German Oro stock, which, was reported to reproduce
the quality of nitrate with its higher silver content. The Eastman stock
had a greater contrast range with deeper blacks while the Oro had a more
even, but, to me, flatter looking contrast range. The audience was asked
to vote on which it preferred, and opinion was evenly split, probably
based on their own individual tastes in B&W. Film Technology did the lab
work.

Politically
Incorrect In "The Mask Of Fu Manchu" |
Richard May then showed how potentially
problematic elements could be made to work in restoring missing footage,
with some clips from "The Mask Of Fu Manchu" (MGM; 1932). The film
originally had some lines of dialog that were not considered politically
correct when the film was reissued in the Fifties and the shots
involving them were physically cut from the original negative. They
remained in a composite 35/32 negative that had been made to yield 16mm
prints, and the picture was blown up from that source, as well as the
track sections re-recorded, for the restoration by Film Technology. The
image was only slightly softer than the 35mm original and the tracks
matched quite well. 16mm prints and tracks of varying quality
have been used in the past when no other source was available, but I've
seen and heard nothing as good as this.
Mr. May then presented two clips from recently restored silent films
whose negatives had been thought to have been junked years ago. "Tell It
To The Marines" (1925) was from the original negative and had been
printed with an amber tint. Shown at full 1.33:1 aperture , it was very
sharp and was beautifully accompanied by a gentleman from Film
Technology whose name I didn't catch, who'd earlier come out in a
Chinese outfit with a gong to introduce the "Fu Manchu" clip. Film
Technology did the lab work on this clip.
Mr. May then showed the ending of "The Big Parade" (MGM; 1925), the
subject of a major restoration by CFI/Technicolor and a re-"premiere"
with a live orchestra at the Goldwyn earlier this year. The original
tinting and toning guide sheets were still in the files and used to
recreate the look in printing. A print was made off the original
negative as well as new preservation elements on color intermediate
stock. The excellent clip used was from the dupe negative and had a
sonically cleaned up version of the music track added for a 1931
reissue. Though not part of the clip shown, digital technology had been
used to add red to just the cross on a red cross truck which had been
hand-painted in original 1925 prints of the film.
The evening ended with the "June Is
Bustin' Out All Over" number from Schawn Belston's recent restoration of
"Carousel"
(20th Century-Fox; 1956), whose re-premiere I wrote about recently and
more details of which can be found in a superb article by Robert S.
Birchard in the current issue of American Cinematographer. That film's
original negative had faded too badly for a photochemical restoration so
the decision was made to do it digitally, but scanned in and out at 4K.
As I noted, problems with the original photography make it difficult to
evaluate the degree of success, though the results look better than any
print from an anamorphic original that I've seen that went through a 2K
digital intermediate.
The consensus of the presenters was that the bulk of preservation and
restoration will still be done photochemically, because it's cheaper and
the end result is likely to be preserved on film. Film is still the only
guaranteed storage medium for both picture and sound, adhering to
standards that go back 90 years or more so that a negative shot that far
back can be printed on modern equipment just as a print from back then
can be run on contemporary projectors (allowing for shrinkage, of
course.) At present, not only are there no standards for digital
technology, but hardware and software changes raise questions about the
ability to recover digitized material in the future; the longevity and
stability of the media on which that material is stored is also a
subject of debate.
In recent years I've seen an amazing number of new prints of
black-and-white films from the Thirties and Forties made from dupe
negatives that look better than the nitrate prints off the original
negatives I ran in my USC days. Ten years ago we were lamenting the loss
of most of the Fifties films shot on Eastman Color negative because of a
combination of dye fading and badly-made separations, yet in recent
years amazing new prints have been struck off those original negatives,
followed by new separations made to today's exacting standards. What
remains of our film heritage is in good hands, to date.
APPENDIX
From conversations I've had and things Ičve overheard, some people are
still confused about certain past industry practices that have hurt and
helped restoration and preservation.
One important point deeply affecting film preservation that astounds
many people today is that prior to about 1969, except for those made by
the Technicolor dye transfer process and some other arcane color
processes, almost all release prints were made off the original cut
camera negatives! The number of prints varied depending on the
release pattern and popularity of the film, but between 250 and 300 for
American release seems to be the average. I recall one source stating
300 for domestic release and another 150 for foreign release, and Robert
A. Harris (who was in attendance at the program) and Jim Katz have the
paperwork confirming that 382 color positive prints were made of "Rear
Window" at the time of its original 1954 release. (At a screening of
"Frenzy" [1972] Alfred Hitchcock stated he never liked the softer image
of Technicolor IB and was happy that they were now making sharper color
positive release prints from CRIs; at that time the lab was actually
doing both.)
Naturally this subjected the negatives,
dry printed at a top speed of 350 per minute as compared to today's
2,000 per minute from a timed, spliceless polyester internegative, to
the rips, torn perforations, emulsion gouges, etc. that have to be
corrected in restoration. In fact, it's amazing how many negatives have
held up as well as they have.
The reason for this practice was a concern for image quality that
appears to have begun around the end of World War I. Prior to this time
it was a common practice for companies shooting outside New York to
project the developed negative as dailies and edit the film in that
form, sending the spliced result to New York for release printing, as
almost accurately depicted in Richard Attenborough's "Chaplin" (TriStar;
1992) (the cuts were too on the nose and there were no zoom lenses in
1915), which would also explain the disastrous first screening of "The
Squaw Man" (Lasky; 1914). I've not been able to find any official
historical documentation, unless there is something on the subject in
early SMPE Journals that are missing from various local libraries, but
after the industry settled in the Los Angeles area and began using more
professional laboratory techniques, they began the practice of pairing
two cameramen with their cameras as close as possible and with the same
focal length lenses, one to shoot the negative for the domestic release,
the other for the foreign. Once the domestic version was approved, the
foreign negative would be cut to match, scratch intertitles inserted,
and the results sent, usually to London, for foreign printing
operations. Because foreign countries were more respectful of films than
Americans, many silent films have been preserved from these foreign
versions. (In the late Forties and early Fifties, 20th Century-Fox had a
variation of this practice in which two takes of each set up would be
circled. Once the domestic version was approved, the first assistant
editor would get experience by editing a foreign version using these
alternate takes. Other studios may have also done this, but my source
for this information was Bud Hoffman, nephew of Fox's chief editor at
the time, Barbara McLean, and her assistant in the early Fifties.)
Obviously this type of thing could not be done for talkies as two or
more cameras were being used just to get the simultaneous coverage
needed for the domestic version. Unfortunately the intermediate stocks
available at the time were not deemed good enough to make dupe
negatives, so initially many companies would shoot French, Spanish, and
or German versions of select films, an expensive practice killed by the
Depression. Since improved intermediate stocks were needed for optical
effects that could no longer be done in camera, they began to appear in
the early Thirties and some companies did begin making dupe negatives
for foreign release. In other instances, the original camera negatives
would be shipped overseas for printing after all domestic prints, and
some type of protection element, had been made. This was a dangerous
practice and legend has it that the original negatives of "The Prisoner
Of Zenda" (United Artists; 1937) and "The Best Years Of Our Lives"
(Goldwyn/RKO; 1946) were lost when the ships freighting them went down.
For domestic distribution of a foreign, usually British, film, the
studios usually brought over the original negatives and often inserted
specially shot material to accommodate the Breen office. Because few
prints were needed for foreign language films, they were often made and
subtitled in the country of origin though often inferior dupe negatives
were sent over on others.
Although, as one can see from the quality of optical effects dupes, by
the late Forties, black-and-white intermediate stocks and processing
techniques could yield dupe negatives good enough to release print from,
the American industry continued to print off the original apparently
because it was the way they'd always done it. The color negative stocks
introduced in 1950 created other problems. Initially only Eastman
introduced a separation and complementary internegative stock for titles
and opticals and the results still give film restorers nightmares.
Eastman's introduction of the 5253 multilayer IP/IN stock in 1956 was
not much of an improvement. (I don't recall whether Ansco, Eastman's
only competitor in the US at the time ever introduced an intermediate
stock.) For foreign release, the prints were either made in New York
(only Technicolor, MGM, and Columbia are known to have done their
release printing on the West Coast), from original negatives shipped to
Europe, or the foreign release printing subcontracted to Technicolor,
who made matrices which were shipped to its London and later Rome and
Paris plants. When the studios picked up a foreign made film for
domestic release, they either brought over the original negative or also
subcontracted the work to Technicolor. For their American release, as
with black-and-white, some arthouse foreign films used imported
subtitled prints from their country of origin, some were printed by
Technicolor, but many were printed from internegatives and looked awful,
very contrasty and grainy with distorted colors.
Solving this problem was reportedly one of the reasons Eastman developed
its now controversial Color Reversal Intermediate (CRI) stock,
introduced in 1968. Within a year this was also being done for domestic
releases and by the early Seventies had become standard, with only about
ten prints being made off the original and used in a film's first run
presentation in major theaters in Los Angeles, Chicago, and New York.
One problem with CRI was that unless it was overexposed for printing at
a high light, it would not yield deep blacks (I learned this from Jim
Elkin at Universal Optical and Tom Shaffer of Technicolor in the
mid-Seventies). Eastman's introduction of 5243 IP/IN stock in 1978
corrected this as well as the problems with the earlier IP/IN stock and
it had supplanted CRI by 1980.
There is also the question of the origin of the practice of making what
would become protection elements, which apparently were not made on
silent films at the time of negative cutting as most films were
considered worthless after their initial theatrical runs. (According to
the late Jack Rush, former head of Universal's stock footage library,
that company's late Forties owners intentionally junked the negatives of
its silent films to make room for current productions in their New
Jersey vaults.) During the silent days, if a section of negative became
damaged, the section or shot was cut out of the negative and thrown
away.
This could not be done with sound films, of course as the picture and
track negatives had to be kept in sync. Vitaphone actually sent out
rolls of black leader and instructions to projectionists as to how to
use the numbers inked along every foot of the print to replace the right
amount of damaged footage; Scott Eyman reprints these instructions in
"The Speed Of Sound." This was also done with damaged negatives of both
disc and optical sound films, using clear leader which printed as black.
This explains the black frames that often occur in some older films, and
can be objectionable if the damaged section is unusually long; I once
saw a film that was blacked out for over a minute.
I'm not quite certain whether I heard this from Sid Solow in his USC
class or in passing at one of the many SMPTE programs I've attended, but
I recall someone alluding to some unnamed party at some unknown lab
coming up with the idea of using the contentious practice of duping,
which unscrupulous labs and distributors had engaged in since the
industry's turn-of-the century vaudeville days, to solve the problem.
Duping was making a negative off another company's release print and
selling it as their own, and in this instance involved making a dupe
negative of the damaged shot off a print and cutting it into the
original. Soon, first struck prints were being set aside for this
purpose, then they were being specifically developed to lower the
contrast and grain to yield better dupe negatives, and finally, as noted
earlier, specific stocks were developed for this purpose. And, as noted,
because such intermediates made it easier to make 35mm dupe negatives
for export and printing elements for smaller gauge prints, making them
would become standard practice and the primary preservation element used
today.
An aside for those who might be interested: there is a shot duped from a
70mm work print in "Star Trek: The Motion Picture" (Paramount; 1979). In
principal photography, all shots that were to incorporate optical
effects were shot in 65mm, except in all but one instance: blue screens.
As a 65mm camera had been set up in the rafters for a high shot of the
engine room to which effects were to be added, it was decided to shoot a
non effects shot from that angle in 65mm as well. Naturally, in the
furor to finish the film's effects work, this straight reduction shot
was forgotten and when they finally got around to it, the negative
couldn't be found. For whatever reason, instead of using another take,
the decision was made to dupe the 70mm work print, which had only been
projected once. Naturally, as assistant film editor responsible for
cutting in the effects shots, among other things, I know which
shot it is, but no one else seems to have spotted it.
National Telefilm Associates, or NTA, was formed in 1954 by two persons
from 20th Century-Fox distribution and licensed the pre-'48 Fox films
for TV syndication. Over the years they picked up a number of orphan
libraries, such as the Bank of America-financed Universal films of the
late Forties on which the bank had later foreclosed, the Pine-Thomas Bs
for Paramount, the Cary Grant library, etc., but their biggest success
was the Republic library, which was so popular that in the Eighties,
they changed their corporate name to Republic.
Though advertised as being in "Trucolor by Consolidated Film
Industries," "Johnny Guitar," like almost all "Trucolor" films released
after 1951 was shot on Eastman Color Negative, rather than the earlier
two-color bipack method. According to the late CFI president Sidney P.
Solow when I took the color processing class he taught at USC in thee
Seventies, release printing was done from separations because the lab
was used to working that way, especially for timing, with the two-color
system, even after they'd begun printing on color positive stock.
The only exception to color negative
photography was "Montana Belle," originally made in 1948 by an
independent producer at Republic for intended distribution by them.
However, because the film co-starred Jane Russell, Howard Hughes bought
it and finally released it through RKO in 1952, apparently the last
two-color Trucolor release.
With the introduction of optical sound to 16mm in 1932, it was
considered an educational tool as well as a potential downmarket source
for theatrical films. For the previous nine years, prints on 16mm and
similar smaller-than-35mm gauges had been made by optical reduction
printing from a 35mm negative directly to 16mm print stock.
Unfortunately the laboratory processing machines of the time used
rollers with teeth that engaged the perforations of the negative and
print stocks and processing 16mm required changing those rollers
whenever the gauge was to be handled. According to an ad his company
published in the American Cinematographer in the early Seventies, Byron
of Byron Laboratories came up with the idea of optically printing the
16mm images to a 35mm dupe negative stock with 16mm perforations inside
the normal 35mm ones. The dupe negative could then be contact printed to
35/32 print stock which would then be slit down to 16mm after
processing. In fact, two rows of 16mm images could be printed, one reel
in one direction, the other in reverse, with optically reduced tracks
for both reels also printed on the dupe negative. With everything
pre-timed to print at one light, 16mm prints could be made at any lab in
the world.
Technicolor would come up with its own variation of this for its dye
transfer process, a row of 16mm images printed down the center of a 35mm
matrix, called single rank, later two images side-by-side for double
rank (they reportedly also had a Super 8 version called quad rank).
Although in the Forties, they experimented with a dye transfer track
from the yellow matrix, they generally went with a silver track which
had to be added in a separate pass as in 35mm. I've never been able to
get a definite date as to when Technicolor began making 16mm IB prints,
but some sources have cited a 1944 Walter Lantz cartoon as the first.
Prior to Eastman's introduction of its 5253 IP/IN stock in 1956, the
only other way to make 16mm color prints was by reduction printing from
a 35mm print to 16mm Kodachrome or Anschochrome.
The Academy's Dunn and Goldwyn Theaters are among the few that can show
silent films at full aperture, where such prints exist. Normally,
they're shown via 1.37:1 Academy mask, which cuts off the top and
bottom, as well as the left side of the frame to restore the basically
square frame after optical sound was added. Of course silent films to
which tracks have been added generally have to be shown this way as do
early sound films shot for disc systems. Last year, the early optical
sound films "Sunrise" (1927), "In Old Arizona" (1928) and "The Love
Parade" (1929) were shown at the Goldwyn Theater at the "Movietone"
aperture of @1.15:1, the height of the silent frame but with the left
side taken up with the sound track.
Tragically 16mm preprint elements and even 35mm elements on such films,
when handled optically, were made on optical printers with Academy
aperture masks, resulting in images off center to the right and with the
top and bottom of the frame cut off. In recent years, where the full
aperture negatives still existed, they've been optically reduced to
Academy aperture, as Universal has done with "Dracula" (1931), for
example.
