LOS ANGELES—The capabilities of smallformat
digital video cameras keep improving.
Now even high-speed digital photography
is becoming affordable for digital
cinematographers.

The Phantom Miro M320S from Vision
Research is a rugged, high-speed camera
that can shoot 1,380 fps at 1920x1200 or
more than 1,500 fps at 1920x1080, thanks
to 10 μm pixel microlenses on its customdesigned
CMOS sensor. That sensor also
gives it significantly enhanced light sensitivity
for a 2-megapixel camera with 3.2
gigapixels per second throughput.
Scientists and engineers have experienced
the benefits of the Phantom Miro eX
series cameras since 2007. But with the latest
generation M series of Phantom Miros,
independent filmmakers are also learning
how a camera that captures all that overcranked
data can enhance their digital productions.
FROM SCIENCE TO ENTERTAINMENT
“Whenever you see a slow-mo car crash
test on TV, chances are it was shot with a
Phantom camera,” begins Rick Robinson,
director of marketing at Vision Research in
Wayne, N.J.
“Introduced in 2011, the Phantom Miro
family was originally targeted at the scientific
community, but we soon realized that
with the addition of features such as an
HD-SDI output port, it would be very attractive
to digital cinematographers,” Robinson
says. “Then ... at the [2012] NAB Show we
brought out the Miro M320S, which is capable
of shooting 1,540 fps in 1920x1080
HD. We gave users the choice of four lens
mounts: F-mount, C-mount for scientific/engineering
applications, or PL-mount or EOS
styles to meet the needs of digital cameramen.
It also has 12-bit pixel depth for excellent
image quality to satisfy the hunger for
high-speed imaging at an affordable price.”

The Phantom Miro M320S starts around
$45,000 and, depending on the accessory
package, can go up to $60,000. That’s about
half the cost of a Phantom Flex, although
the Miro line does not have the Flex’s level
of resolution, write-to-storage speed or recording
capacity.
Video clips are saved in the camera’s internal
RAM (three, six and 12 GB capacities
are available). Utilizing Vision Research’s
own removable, non-volatile CineFlash storage
technology, the Miro M320S can quickly
save 10-bit log raw cine files from the camera’s
internal RAM to 60, 120 or 240
GB CineFlash modules. Their contents can
then be downloaded through a docking station
to a computer with the help of Phantom
Camera Control software.
The M320S supports Vision Research’s
new Phantom PH16 protocol, providing
it with enhanced white balance and color
processing controls. To help calibrate the
camera when shooting in widely varying
lighting conditions or high dynamic range
situations, the Miro M320S has an internal
shutter that covers the sensor before every
take. This gives the camera an absolute
black level reference for each shot for the
best possible image quality.
TESTING THE CAMERA
Cinematographer and editor Jim Geduldick
was an alpha tester of the Miro M series,
having received the first two that came off
the production line a month or so before
April’s NAB Show. He wanted a pair of the
cameras so he could configure one with a
PL mount for his ARRI lenses and the other
with an EOS mount for Canon glass.
When we spoke, he was using a Miro
M320S on a documentary about a blind
judo athlete training for the 2012 Paralympic
Games. “When shot at high frame rates,
judo is really like a ballet between two dancers,”
Geduldick says. He praised the small
form factor of the Miro M320S and its attendant
flexibility, noting, “Camera movement
is what sets high-speed videography apart.”
But Geduldick learned that if you shoot
at the camera’s highest speed, 1,540 fps at
1920x1080, you’ll quickly fill up your recording
media. He recommends relying on
the camera’s built-in shot trimming capability
in RAM and having a download station
nearby to free up those CineFlash modules.
He also recommends experimenting
with wide-angle lenses for close-ups. “Seeing
the sweat drip off a trained athlete’s face in
slow motion can be almost sensual,” he tells
me, “but remember that high-speed shooting
requires a lot of light. The Miro M320S is
amazing in daylight, but you’ll need a lot of
tungsten if you’re shooting indoors. So you
need to watch for the flicker if you’re shooting
under something like stadium lighting.”
Steve Romano is a New York-based DP/
digital imaging technician who has been
using Vision Research cameras since the
original Phantom HD. He has used the Miro
M320S to shoot music videos, promos and
a show produced by True Entertainment
called “Too Cute” for Animal Planet.
“This camera is kind of like a GoPro
HERO camera, but with a high frame rate,”
he says. “It’s so light, it lets me get shots I
could never get before using larger cameras
without massive Steadicam rigs.”
To keep the video noise level down in
his high-speed shots, Romano recommends
that you crush the blacks (lower the black
level). “Always keep a 5K or greater light in
your kit so you have enough illumination,”
he suggests.
Like most high-speed cameras, the Miro
M320S shoots in a loop mode with a circular
buffer, so Romano finds it imperative to
black balance regularly. “You may be waiting
minutes for something to happen, and by
the time it does, you have lost your original
black balance,” he says. “So use the internal
shutter to black balance all the time.”
Romano makes sure he always gets insurance
when renting a camera like the Miro
M320S. “If you have a camera small and light
enough to strap onto a running dog, people
are going to do it,” he laughs, “so you better
keep yourself covered whether renting or
buying.”
Trent Kamerman, owner of 800Kamerman
(a company name that doubles as a
toll-free phone number), and his production
manager/producer, Nick Balogh, use their
Phantom Miro M320S mostly for ENG work
for clients including ESPN. “I bought the
camera right at NAB, and Vision Research
made sure we had it in time for June’s X
Games 2012,” Kamerman reveals. “We had
Nick stand on the top of the MegaRamp to
shoot skateboarders flying by to catch big
air. Shooting at 500 fps, you could actually
see what the athlete’s feet were doing on
the board.”
The camera’s workflow let them get
footage into the ESPN truck “super fast,”
Balogh says. “We kept a Sound Devices Pix
240 recorder on hand so we could offload
our footage and play the shots on the monitor
in DNxHD right away. We call it ‘baking’
the shot, and it let us get the footage to the
ESPN production truck as fast as possible.”
Like all the cinematographers using the
Miro M320S, Kamerman and Balogh found
that shooting high speed smooths and stabilizes
all the imagery it records. “You can go
from the bottom of a bike wheel all the way
up to the rider’s face and it looks rock solid,”
Kamerman says. “It was an incredibly fast
shot when I took it, but when slow-mo’d, it
looks super dramatic.”
Better, faster, cheaper. Digital camera evolution
is a wonder of our age.
