Checking in with the
Phantom Flex4K
High-speed camera manufacturer Vision Research recently debuted several new
features on its unique high-speed digital cinema camera, the Phantom Flex4K...

T

he Flex4K is a professional camera,
designed for cinematography,
capable of shooting normal sync-sound
frame rates, and up to 1,000 frames
per second (fps) at 4K resolution. Since
the camera started shipping in 2014,
the camera has been used primarily to
capture high speed and visual effects
elements, and for projects ranging
from super slow-mo sports broadcast
to high-end commercial production.
"We are excited by the initial
response to the camera," states Toni
Lucatorto, Product Manager at Vision
Research. "Feedback from the cinema
community usually includes 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.
The camera really excels for VFX
production - taking advantage of the
4096 × 2304 resolution sensor with
extremely low noise characteristics.
Recent Updates
Updates to the camera system are
targeted to improve the workflow
for both standard and high-speed
recording.
For
ultra-high-speed
recording, the general rule is the more
RAM available the better. The Flex4K
is now available with up to 128 GB of
RAM, which allows ten seconds of realtime capture at 1,000 4K fps. Those
ten seconds will play out in over six
minutes at 24p.
A typical Phantom workflow involves
raw cine files recorded to the camera's
CineMag IV recording media. These

raw files are of the highest quality
and are compatible with a growing list
of the industry's top colour grading
systems, but they can also be quite
large and expensive to manage. Every
hour of 4K playback takes up 1 TB of
space - before the files are rendered.
With the option to record in the
popular Apple ProRes 422 HQ format,
footage will be easier to manage for
productions where the raw files are
not required. It also allows more
footage on the CineMag IV by reducing
overall file size, without sacrificing
image quality, and it simplifies the
workflow straight out of the camera by
assuring file compatibility with more
programs.
Also
planned
for
release summer 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

Flex4K from the 2015 NAB Show floor, all set up for Audio capture

equipment the camera will capture
uncompressed .wav files that are
downloaded along with the footage.
The audio can be monitored oncamera via a digital AES output or the
analog headphone jack.
Flex4K and Sports Broadcast
The Flex4K is also well suited for
live broadcast applications, and has
become a staple 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.
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, sometimes referred
to super-zoom systems, such as the
Evertz Dreamcatcher at up to 2160p30.
The camera also includes the 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.
What's new at BroadcastAsia 2015?
If you're at BroadcastAsia be sure
to visit the Vision Research booth
to meet the team and receive a live
demonstration of everything new with
the Flex4K. Vision Research will also
be showing its Phantom Miro LC320S
camera, which is a fully portable
camera with battery support and
touch-screen controls, that shoots up
to 1,500 fps at 1080p resolution.
