With
so many Hollywood movies moving north of the border,
is it any wonder that major advances in digital cinema
would occur in Canada? James Tocher (pronounced "talker"),
is an experienced Director of Photography (DOP) with
15 years of shooting documentaries, music videos and
features in both film and video. James has earned
a bit of a reputation as a specialist on how to best
shoot video when transferring to 35mm film.
It
helps that in 1999 Tocher founded Digital Film Group
of Vancouver, B.C., a very successful video to film
transfer facility. He started it with a collective
of other filmmakers, dedicated to providing true film
resolution from NTSC and PAL transfers at a price
that is affordable to independents.

It seems
to be working. Digital Film Group's recent transfer of the epic
DV feature film" The Fast Runner" ( picked up by Lot
47 in the US) won the prestigous Camera D'or at the 2001Cannes
Film Festival. In fact, Tocher's little company has blown up films
that have now garnered 18 international film awards including
four Oscar submissions in just over two years!
"We started
out to bust this myth that you had to shoot in PAL to achieve
good video-to-35mm results." Because PAL video is a 25 frame-per-second
format, it has, historically, been the first choice of low budget
cinematographers seeking to use video to break into 24 frame-per-second
film venues.
James explains,
"With NTSC, typical film conversions would throw away every
other field before converting to 24 fps. This results in a 50%
loss of resolution.
"When
contemplating NTSC, which is 30 frames-per-second, the process
of throwing away 6 frames (12 fields) ever second created disconcerting
skip-motion effects. We started our research on the premise that
you could at least equal the quality of PAL by not throwing any
frames away. Our process, therefore, takes the 6 extra frames
and blends them seamlessly back into the 24 frames of film, thereby
enhancing the quality of the end result. By avoiding de-interlacing,
we therefore retain greater resolution for both NTSC and PAL conversions
and eliminate all motion errors." Tocher continues, "Since
PAL cameras are not so easy to find in North America, the advent
of our technology is making NTSC digital cinema the preferred
video-to-film medium."
At a recent
"Creative Digital Forum" at Manhattan Studios in New
York City, sponsored by JVC, Jim Tocher demonstrated early tests
he had conducted, transferring NTSC from High8, DV, DVCPro, BetacamSP,
Digital Betacam and D-9. While even the primitive tests were impressive,
the latest results, using Digital Betacam and D-9 drew applause
and praise from the usually critical New York audience of professionals.
DFG's process
boosts NTSC's 525 line interlaced video original up to 2,000 lines
of resolution, pixel-by-pixel (as well as PAL). The process even
adds the kind of edge blurring on moving objects that is natural
in film, but never seen in video because of the interlacing of
fields.
One of Tocher's
tests compared a 35mm scene of a key lit dancer on a black background.
As the dancer waved her arms, distinct motion blurring produced
faint, ghostly, "after images" of her arms (reminiscent
of another Canadian, Norman McLaren's seminal, "Pas De Deux").
Tocher then followed this scene with the same dance, shot on D-9
and converted to 35mm using the DFG's "Smooth Motion"
process. Again, the same motion blurring appeared and, when combined
with the authentic graining effects of the process, created a
compelling film "feel." This reporter witnessed absolutely
no video lines in the 35mm projection, although slight aliasing
on high contrast, thin diagonal lines, such as blond hair on a
dark background or a thin, gold eyeglass frame could easily be
seen by a discerning eye.
"I believe
that digital projectors will be in widespread use in three to
five years," admits Tocher, "But our group thought there
was a real market for a proprietary software process to convert
NTSC and we are now enjoying a good flow of clients. There are
also other reasons for transfering to film, such as giving the
analog life and texture back to the video as well as the longterm
high quality masters that can be stored indefinetly.
"Noroc,"
Tocher's first feature film, shot on D-9, employing the DFG process,
directed by Marc Retailleau of Vancouver was shot under the ten
rules of Dogma (a cinematic style which restricts the film maker
to abide by 10 rules, such as using only available light and sound,
hand holding, etc.). Made for about $100,000 Canadian and brought
a line of low budget producers to Digital Film Group, eager to
explore NTSC feature production.
"While
a film-based crew would be really restricted under the ten rules,
NTSC photography was quite easy." Recalls James, "At
times we used existing sunlight, even sunsets. I recall film shoots
where the crew could not set up their equipment in time to capture
a "magic hour" shot. With a video equipment package,
this is never a problem. On "Noroc" if some beautiful
light developed, we whipped out the Sony D30WS, and got the shot.
Most other times we were able to light the set with, at most,
one or two practical lights. The results were superb."
Ironically,
Tocher recently won a Best Cinematography award for his work on
a DV short film entitled "Evirati," which successfully
screened at several International festivals and has recently begun
airing on Bravo. "Evirati" is an 18th century period
piece, reminiscent of Kubric's "Barry Lyndon." However,
where Kubric labored to render a few precious scenes using several
hundred candles, Tocher managed to obtain stunning chiaroscuro
effects using only one to four candles.
Clips shown
by Tocher at the JVC forum featured romantic scenes with actors
dressed in ornately embroidered period costume, every detail delicately
painted to the screen with soft glow of paraffin combustion. Other
scenes featured gentlemen in the powdered wigs and stark, white
makeup of the time, yet their skin and hair had none of the sharp
angularity one might expect in
video. This was the art of digital cinematography carried to the
edge of current development.
"In spite
of the enormous demands on gamma range, our cameras managed to
draw amazing details from the blacks while never quite blowing
out the hot centers of the candles which frequently appear, even
in close-up.
Tocher credits JVC's D-9 format with the technical advancements
that made "Evirati" possible. "Without a doubt
on Evirati, we found D-9 to be every bit as good as Sony Digital
Betacam but the cost savings made D-9 far superior. Its 4:2:2
digital profile, recorded to robust half-inch tape yields the
best results of anything we tested, and the cost savings are realized
all the way down the line."
When asked
about lighting equipment, Tocher laughed, "The biggest instrument
we used was a 1.2K HMI. We saved a lot on lighting equipment.
We saved even more on crew, because we could shoot with less than
half the personnel of a film. But we really saved on film. Where
a normal feature will spend about $250,000 on just film and processing,
we spent something like $800 on tape. What we saved, we put elsewhere,
like dollies and steadicams." (and cranes)
Another advantage
of shooting on tape was the seemingly limitless tape length. "With
35mm, the longest take you can get, even using a heavy, 1,000
foot load, is ten minutes. With D-9, for instance, you can shoot
a take that's 110 minutes long. You could, conceivably, do a whole
feature in one take."
While the
challenge of beating Hitchcock's "Rope," (a feature
composed of ten, ten-minute scenes) remains on the table, James
Tocher isn't slowing down. He is looking forward to shooting another
DV feature for kids this summer and of course, he will be spending
time collaborating with other DP's as they discover the ease with
which they can shoot with NTSC cameras and reep the savings of
proprietary benefits of his Vancouver transfer service, Digital
Film Group.
