Keeping up with the
Phantom Flex4K
There seems to be no slowing the Phantom Flex4K down in 2015...

H

igh-Speed camera manufacturer
Vision Research has been busy
working on new features for its
premiere digital cinema camera with
plans to debut them at NAB Show 2015.
The Flex4K is a cinema camera
capable of shooting normal syncsound frame rates all the way up to
1,000 frames per second (fps) at 4K
resolution. Since shipments started
in 2014, the camera has been used
primarily for high speed and visual
effects elements, and projects ranging
from TV Broadcast to high-end
commercials and cinema production.
The camera excels for VFX production
- taking advantage of the full 4K
sensor. In combination with high
speed motion control rigs, the results
become all the more dynamic and
something unique.
Feedback from the cinematography
community is that the Flex4K image
quality is up there with the best. The
Flex4K sensor makes it an ideal choice
because of its excellent dynamic range,
low-noise performance, and versatility
with frame rates, capture resolutions
and output formats. The camera has
proven to be a valuable tool for not
only high-end 4K productions, but also
projects finishing in 2K and HD.
What's New at NAB Show 2015?
Updates to the camera system are
targeted to improve the workflow
for both standard and high speed
recording.
For
ultra-high-speed
recording, one rule of thumb states
that the more RAM there is the better.
The Flex4K is now available with up

to 128 GB of RAM, which allows 10
seconds of real-time capture at 1,000
4K fps. Those 10 seconds will play out
in over six minutes at 24p.
The current workflow involves raw
cine files recorded to the camera's
CineMag IV recording media. These
raw files are of the highest quality
and compatible with a growing list
of the industry's top colour grading
systems, but they can also be quite
large. Every hour of 4K playback
takes up 1 TB of space - before the
files are rendered. At 1,000 fps
that's less than two minutes of realtime capture. The introduction of
in-camera recording with industry
standard compression will allow more
footage on the CineMag IV by reducing
overall file size, without sacrificing
image quality. It will also simplify the
workflow straight out of the camera by
insuring file compatibility with more
programmes.
Another exciting update planned
for 2015 is the ability to record audio
- particularly useful when shooting
standard, sync-sound frame rates.
There is a single AES/EBU stereo
input available to be used as a
reference/scratch sound track. With
the appropriate peripheral equipment,
the camera will capture uncompressed
.wav files that are downloaded along
with the footage. The audio can be
monitored on-camera via a digital AES
output or the analogue headphone
jack.
Flex4K & Sports Broadcast
The Flex4K is also well suited for live

Vision Research's
F4K can be fitted
with various
accessories

broadcast applications, and recently
has been adopted in several major
sporting events around the world.
Vision Research works with integrators
to provide broadcast-friendly solutions
for super slow-motion recording
and playback. American company
Inertia Unlimited specialises in unique
camera systems and has integrated
Phantom camera systems available
for rent, under the X-MO name. The
Belgian company I-Movix offers several
integrated products, including the
X10UHD that has the ability to stream
images continuously. Its systems are
available around the world through a
network of service providers.
Several in-camera features are
geared towards supporting these
camera integrators in the sports
broadcast market. The camera
hardware includes an ENG lens port, a
return feed, and 24-axis multi matrix
control, which enables fine-tuned
colour matching.
Video
engineers
have
been
impressed with these results and the
ability to match the image with the
most common professional broadcast
cameras used today. The UHD video
outputs interface well with pan and
scan systems, such as the Evertz
Dreamcatcher at up to 2160 p30. The
camera also includes an advanced
version of Vision Research's Versatile
Dual-HDSDI feature, which provides
simultaneous live and replay feeds,
enabling continuous capture and
an uninterrupted live feed, which
ultimately increases the value of the
system.

The Maxiva Multi-Compact
series comprises high density,
4RU 19" rack-mounted UHF and VHF
transmission systems

About Vision Research Inc.
It all started in 1950 when a young,
idealistic, engineer quit his job at
Fairchild Camera to pursue a career
in an industry that barely existed. He
formed a brand new company named
Photographic Analysis Company whose
sales mark was "Research Through
Photography."
In 1992 the company decided to
form a separate entity that was to
design and fabricate high speed
electronic imagers, that did not rely
on photographic film for imaging.
That "spin off" was later to be known
as Vision Research Inc. and its family
of electronic imagers is currently
marketed under the "Phantom" trade
mark.
Vision Research prides itself in the
high resolution of its images, the
power of its software, the reliability
of its products, and its high level of
attentiveness and dedication to its
customers.
If you're at NAB Show be sure to
stop by Vision Research's booth for a
live demo of everything new with the
Flex4K. Vision Research will also be
showing its compact, lightweight, and
portable Miro LC320S camera, and
workflow solutions for the Flex4K.
Other exhibitors showcasing Phantom
cameras include Abel Cine, and i-Movix
for its integrated sports systems.
