LDK 4000 Elite
SINGLE-FORMAT HD CAMERA
The LDK 4000 Elite is available as
either a 720p or 1080i camera head. In
each case, its operating frequency is
switchable between 50- and 59.94 Hz,
enabling it to support a variety of
production environments.
KEY FEATURES
Grass Valley™products offer the most
comprehensive multi-format solutions
for acquisition, production, storage,
playback, and transmission—and a
strong foundation for centralized,
proactive status and activity monitoring.
These solutions include one of the
broadest selections of standard-
definition (SD) and high-definition (HD)
digital video cameras.
With one of the best-known imaging
design teams in the world and multiple
technical Emmy®awards, Grass Valley
camera products continue to break
ground for innovation and creative ideas.
In many regions of the world, there is
no standard format for HD production.
Others regions have standardized on
only a single format—or do not yet
support multiple formats. And then
there are production companies who
work in only a particular format. These
circumstances have created the need for
a cost-effective acquisition solution, one
that provides a single, fixed format for
HD production.
Single-Format Camera for Cost-
Effective HD Production
The LDK 4000 Elite is available as
either a 720p or 1080i camera head. In
each case, its operating frequency is
switchable between 50- and 59.94 Hz,
enabling it to support a variety of
production environments.
As well, an optional service pack is
available to transform the camera head’s
initial format from 720p to 1080i or the
other way around. Please note that this
conversion is semi-permanent and not
instantly switchable.
Three 9.2-million pixel HD-DPM+™CCDs
within the LDK 4000 Elite camera ensure
the highest quality image capture, and
14-bit analog-to-digital conversion takes
that quality to the digital domain. Digital
signal processing (DSP) takes place on
a single chip at 34 bits. This processing
includes all major camera functions such
as gamma, knee, contour, and variable
matrix. This single-chip approach delivers
tremendous benefits in speed, power
consumption, and temperature.
The LDK 4000 Elite camera has a
magnesium-alloy body that not only
gives it a high degree of durability, but
also makes it the most lightweight
camera in its class—one that is ideal
for handheld operation. And with a
rotary HD triax connector and optional
integrated handgrip zoom control, it
makes those difficult low-level shots
much easier to achieve.
You can also mount the LDK 4000 Elite
camera in our SuperXpander large-lens
adapter for the use of box-style studio
lenses and a high-quality 7-inch HD
viewfinder to provide the feel of a full-
size studio camera.

Enhanced Digital Signal
Processing Chipsets
The LDK 4000 Elite includes all-new
DSP circuits and an updated software
platform that performs all camera image
management functions such as knee,
gamma, contours, and variable matrix,
with 34-bit digital precision.
New features of the LDK 4000 Elite have
added to those already included with the
LDK 4000 mk II. New circuit and chip
designs provide substantial performance
improvements to the camera.
Additional new features have been
added, such as secondary color
correction, where users can select
specific colors in a scene and modify
them as needed to enhance or highlight
certain features within a shot. Color
selection is divided into 16 vectors.
Users can select the width or range
of colors included in a selection, then
choose the color they wish to modify.
Up to three colors can be modified in a
scene. Selected color changes can be
saved with scene files during rehearsals
then recalled during production.
Other new features include a user
selectable noise reducer. While camera
performance of the LDK 4000 Elite has
already been improved over the LDK
4000 mk II, this feature allows users
to further extend the performance if
needed. In default mode, the noise
reducer is off. Users can select one
of three levels of incremental noise
reduction.
Another function of the new chipset is
color temperature correction. A wide
choice of color temperature settings are
available to ensure repeatable accuracy
at each color temperature point. This is
one of the key differences between LDK
camera architecture and other cameras:
the LDK cameras do not use optical color
correction filters.
Easy Production System
Integration
The LDK 4000 Elite camera readily
integrates into a studio or mobile
production environment. The dockable
camera head supports a range of
adapters and options to enable the use
of either HD triax, fiber, or wireless
connectivity, whether in handheld or
studio configurations.
All system components of the LDK
4000 Elite camera offer the same
operational features as our LDK 8000
Elite multiformat HD camera. So you
have complete compatibility with regard
to connectivity, operation, and picture
quality.
The LDK 4000 Elite system also uses the
same operational control panels as other
Grass Valley LDK series cameras and
with our Ethernet-based C2IP camera
control system up to 99 cameras can
be connected into a single system to
share control-room facilities or centralize
operations.

LDK 4000 ELITE SYSTEM
DYNAMIC PIXEL MANAGEMENT
By grouping the 4,320 vertical sub-pixels on the CCDs to map to the desired line rate, all popular
video formats can be acquired without compromising image quality.
1920 Pixels
4320
Sub-Pixels
1080p When four vertical sub-pixels
are combined per scanning line,
the total line count becomes
1080 lines (4320 / 4 = 1080). So, a
1920 x 1080 image is obtained
with a 16:9 aspect ratio.
720p When six vertical sub-pixels are
combined per scanning line, the
total line count becomes 720
lines (4320 / 6 = 720). So, a 1920 x
720 image is obtained with a
16:9 aspect ratio.
The advantage of working with this lower line
count is that higher frame rates can be used
for creating slo-motion effects in post
production.

Cinemascope-Style Aspect Ratio
When three vertical
sub-pixels are combined per

count becomes 1440 lines
(4320 / 3 = 1440).
By using the center 1080 lines, a 2.37:1 aspect
ratio is achieved without the need for
anamorphic lenses while maintaining full
1920 x 1080 resolution.
