Focus on Editing: Jay Ankeney
Posting a Feature in 480p
There
is a lot of excitement in video production circles these days
about the wonders of shooting digital cinema feature films with
24-frames-per-second high-definition video, thanks to Sonys
new CineAlta camera. But another recording format is starting
to ride the digital storm and is increasingly becoming of interest
to independent E-Cinema producers who cant afford a full
high-def budget. Its called 480p and is being brought into
the widening digital production circus by Panasonics DVCPRO50
progressive camcorders and VTRs.
The 480p format records 60 progressively scanned
images per second, producing high-resolution, if not high-definition,
images that appear more like film than standard videos conventional
interlaced recordings.
FILM TRANSFER
Because Panasonics AJ-PD950 DVCPRO50 multistandard
studio VTR with progressive scan recording and playback offers
a digital video data rate of 50 Mbps with a mild 5:1 DV-based
compression, 4:2:0 signal processing and four 16-bit 48 kHz sampled
channels of uncompressed digital audio (and is also compatible
with the companys cost-efficient 25 Mbps DVCPRO tapes),
this 480p deck provides an ideal source to feed Panasonics
AJ-UFC1800 Universal Format Converter to up-res DVCPRO50P recordings
to all popular HD formats and also insert or remove the 3:2 pulldown
needed to transfer to film for theatrical distribution.
"With 60 complete frames per second, 480p
delivers sports and fast-moving action with far greater clarity
than 24 fps film or 30 fps video," said Doug Leighton, product
marketing manager for Panasonic Broadcast & Television Systems.
"We also feel its the perfect format for upconverting
and intercutting with HDTV formats for both DTV broadcast and
digital cinema applications."
What makes 480p production especially appealing
is the rental cost of Panasonics AJ-PD900WA DVCPRO Progressive
camcorder, which features three 2/3-inch M-FIT CCDs. As a list
rate comparison (although nobody really pays list), Hollywoods
Plus8Video will rent a widescreen 24p CineAlta camera for $1,750
per day. A 16:9 DigiBeta camera goes for $1,000/day.
HARD TO BEAT
But you can get Panasonics DVCPRO50P camera
for just $800/day. Having seen how beautiful 16:9 images in 480p
look when transferred to film, thats a cost/performance
ratio hard to beat.
Michael Caporale, owner of Caporale Studios in
Cincinnati, was so enamored of the AJ-PD900WA progressive camcorder
that he purchased his own for both theatrical feature production
and general video assignments ranging from national commercials
to video news releases. With it, he has recently completed principal
production on a new feature "film" in 480p called "Ball
of Wax," shot entirely in 16:9 with the AJ-PD900WA.
"Ball of Wax" is a darkly satiric look
at American culture through a baseball motif that is, if
baseball were played as a blood sport. It follows a team called
the Carolina Devils that turns to injecting escalating violence
into baseball games to improve ticket sales.
BALL OF WAX
By using the DVCPRO50P camcorder, and deferring
everyones payments, they were able to complete the shoot
on a production budget of just $3,500 an investment rivaling
"The Blair Witch Project."
Shot in Wilmington, N.C., "Ball of Wax"
was directed by Daniel Kraus and produced by Allen Serkin, Jason
Davis and Damian Lahey. Michael Caporale was the director of photography
and will be the online editor. The fact that no edit systems are
currently capable of actually editing 480p, however, presented
some challenges we will examine shortly.
Even without a distributor signed up as yet, Caporale
is determined to take the production to film. "Im a
film guy that is shooting video," he laughs. "With 480p
I can get the cinematic look I want with cost-savings and improvements
in production techniques to actually achieve some things we couldnt
do with film equipment."
For example, in one scene the lead character Brett
Packard, played by Mark Mench, expresses his frustration in the
locker room by taking a practical camcorder and throwing it up
in the air. Director Kraus wanted to maintain the video quality
of 480p for the effect so he eschewed the option of giving the
actor a throwaway replacement camcorder for the stunt. They would
not have risked that gag with a conventional 35mm camera.
Luckily, the actor safely caught the AJ-PD900WA
camera and Caporale could continue with the shooting schedule.
But once the story was in the can, how were they going to edit
it?
With no edit systems that handle native 480p, and
no switchers that can blend its signal, they could have opted
for just linking two DVCPRO50P decks together and resigning themselves
to an A-roll limited cuts-only post of their feature. That would
be pretty disappointing for a project they looked forward to seeing
on the big screen.
SOLVING THE PROBLEM
Some ingenuity was required, but then postproduction
is always about problem-solving. They downconverted the 480p material
to mini-DV, using a Panasonic AJ-HD150 DVCPRO HD studio VTR, so
director Kraus could offline the feature on his Apple G4 computer,
using Final Cut Pro editing software.
Then they had to deal with the fact that the composite
interface to their mini-DV recorder would not carry SMPTE timecode
with the video. That meant that even though they could load the
material onto the G4 through FireWire, there would be no reference
for the offline edits.
The solution? Burn the visible timecode into the
picture. The downside? Someone would have to manually write down
the "in" and "out" points of each edit and
feed them into the online system.
WORTH THE COST
With the offline completed, Michael Caporale will
call upon Caporale Studios Accom Affinity digital nonlinear
edit system to create the online master. "Well type
the written EDL into the Affinity," he explained, "then
put the 480p tapes into the AJ-HD150 DVCPRO HD studio VTR to downconvert
them into a 480 interlaced signal and load the 480i via serial
digital interface into the Affinity. Once the production has been
conformed in 480i on Betacam SP, we will have a high-quality master
we can submit to festivals, show to distributors and use to raise
funds to make our final transfer to 35mm film."
Caporale figures they could get an acceptable film
release coming from 480i if necessary, but once the EDL is refined
and the picture is permanently locked, they will re-import the
list into Final Cut Pro and put a Pinnacle HD board into the Mac
G4 that can accept a true high-definition signal in 720p.
Then theyll call once again upon the AJ-HD150
DVCPRO HD studio VTR to upresolve the 480p tapes to 720p and re-assemble
"Ball of Wax" in full HDTV. This, finally, will give
Caporale a pristine video source for filming out to 35mm with
no compromises.
NO
PROBLEM
"Ive never had a single problem with
the AJ-PD900WA camcorder or the 480p format," Caporale said.
"The object of this exercise with Ball of Wax
was to shoot it as much like film as we could. I think when you
see the result the cinematic impact will be impressive."
480p production is so new that support equipment
is just coming onto the market. Optibase Ltd., previously Viewgraphics,
actually shipped a 480p native video input/output board in February
2000. Called the VideoPump D-1, it could capture uncompressed
QuickTime movies in this progressive format and, by using the
VideoPump HD card from Optibase, output them in any flavor of
HDTV.
"Since Viewgraphics was purchased by Optibase
just at the end of last year," Blake Homan, director of technical
support at Optibase said, "we are just beginning to ramp
up our marketing of the VideoPump D-1 card. We think there is
a great future for the 480p format in high-resolution video production."
