compression, DV recording media and
conventional hard disk drives. Based on input
from industry principals and leading end users,
JVC has developed a system with the most
sought-after professional features and performance.
Noteworthy ProHD features include full HD
progressive image
scanning, true 24p frame
capture, and a dual
recording system using
tape & HDD. As ProHD
evolves, JVC will continue
to pursue the optimal
method of storage media
for our professional video
products.
The latest addition to the ProHD system is
the GY-HD250, a compact studio-capable

ProHD — Concept of
JVC’s Affordable
HD Solution
1. Full Progressive Scanning (720p)
Leading industry professionals told us that they wanted a full-
frame progressive scanning system that would shoot and
record the highest quality continuous moving images. ProHD
uses the 720/60p progressive format and produces crisp,
native HD images which perfectly
match today’s digital displays and which can be converted
easily, without degradation, to interlaced scanning pictures.
2. Time Code
As a professional system, ProHD products include the facility
to record and display timecode. Convenient menu operation
makes it easy to preset time code at the beginning of a tape.
Simply select REC RUN or re-generation mode. User bits are
also available.
3. Highly efficient video compression
To provide the highest quality HD recording, JVC uses the
broadcast industry standard MPEG-2 Main Profile at H-14.
Offering far greater efficiency than frame-bound systems,
ProHD records at data rates at or above commercial broadcast
rates. Recent advancements in non-linear editing have made it
possible to edit ProHD on virtually all popular non-linear
editing systems. Direct digital transfers via IEEE 1394 ensure
the quality is maintained throughout the transfer process.
4. Dual recording system
Designed to utilize both DV tape and hard disk drives, ProHD
offers the ultimate in media versatility, maximizing productivity
with efficient, economical editing and low-cost archiving. Now
you can safely archive the original tape cassette and then plug
the hard disk straight into your NLE. Editing can start right
away — no need to make dubs or transfer data.
5. Real 24p
With ProHD, the dream of creating HD video with the essence
of film has at last been realized. By capturing and recording at
the film frame rate of 24fps, and offering extensive user
configurable settings such as exposure, gamma and detail,
ProHD becomes an important tool for creative expression. For
the ultimate form of display on the cinema screen, 24 frame
progressive recordings can be readily transferred to 16 mm or
35 mm film. The optional HZ-CA13U Film Lens Adapter further
empowers digital filmmakers by enabling the use of 16mm film
mount.
GY-HD250

1.HD Progressive (720/60p) format for high
quality moving pictures and digital stills
Progressive scanning
JVC’s ProHD products use the same progressive scanning
system used in high-end HDTV cameras. Because the GY-
HD250 uses a full-frame (60p) progressive scanning system, it
has the unique ability to capture and store full frames of image
information. An added bonus of progressive scanning is that it
is a very simple process to convert a progressive image to
interlaced, whereas the opposite is not the case. When
progressive recordings are paused or played
in slow motion, each individual frame
contains the full detail of the original image —
excellent for viewing and analyzing motion.
Stills and prints captured from HD
progressive video avoid the distortion
typically resulting from the combining of two
different frames of interlaced video. In
addition, today’s flat panel television displays
and fixed matrix projectors, such as D-ILA,
DLP and LCD, are all native progressive
scanning systems. This means that JVC’s
progressive HDV recordings can be displayed
without imperfection, because they do not
need to pass through the degenerative
process of de-interlacing prior to being
displayed.
DV compatibility
The GY-HD250 uses the same recording track pitch (10 µm) as
Professional DV, meaning that ProHD also offers track pitch
compatibility with the DV format and the same recording time.
This remarkable HD recording capability was achieved by
developing a new high-power MPEG codec system capable of
maintaining high-definition picture quality, while compressing
the data to 19.7 Mbps bit rate. With its superior resolution and
advanced processing, ProHD delivers top performance in both
its native 16:9 HD mode and in the SD mode. The facility to
make recordings in either HD or SD makes ProHD the ideal
choice for professionals not quite ready to
make the full transition
to HD.
2. True 24p frame capture
24p Progressive Full HD images are ideal for cinematographic
applications. From shooting to editing and distribution, an HD
system can be established for film-like productions. Unlike 24p
images in standard definition, when real 24p HD video is
down-converted to SD, the result is truly film-like DVDs. The
camcorder itself, with its video lens removed and replaced by a
film lens converter system, such as the Mini 35 from P & S
Technik, effectively becomes a digital film camera.
3.JVC’s dual recording system
The optional JVC Hard Disk Recorder DR-HD100 creates a
dual recording system of tape and hard disk. This system is
already utilized by Professional DV users the world over. The
many advantages inherent in JVC’s dual recording system of
tape & hard disk drive are well appreciated. It was only natural
that JVC’s range of ProHD models would include a Hard Disk
Drive recorder and one that can operate equally in DV and
HDV modes. The dual recording system provides fast and
efficient HDD-based editing and cost-effective
archiving, using low-cost tapes. Thanks
to the newly developed MPEG-2
encoding IC, high-quality pictures can
be recorded on readily available
compact DV cassettes, so
running costs are
minimized as no special
equipment or exclusive
media are required. The
DR-HD100 will also be
able to record in the
QuickTime .mov file
format enabling Direct-
To-Edit (DTE) capability
with compatible non-linear
editing systems.
The DR-HD100 can be mounted at
the rear of the camcorder, through the use of
an optional bracket which is offered by the leading
battery systems manufacturers.

Advantages of ProHD
The GY-HD250, fitted with Mini 35 film adapter from
P & S Technik, becomes an ideal digital film camera

With 720/60p capture and recording capabilities,
the GY-HD250 delivers full-resolution HD images,
ensuring the high resolution and smooth motion
critical to news and sports field production. Equally
proficient in the studio, the GY-HD250 can easily be
converted for studio use with the optional KA-HD250,
a specially designed studio adapter incorporating
an industry-standard 26-pin multi-core connection.
Other valuable features of this versatile camcorder
include genlock capability, component and HD-SDI
output, a wide selection of HD lenses, enhanced
cinema gamma, external time code synchronization
and professional connectors on a rugged die cast
chassis.
From live field recording to high-end studio
production, the GY-HD250 is the cost-effective
solution to today’s demand for high-
quality imaging.
GY-HD250 fitted to the
optional Studio Adapter
KA-HD250 and with optional
LCD Studio Viewfinder.
Optimised picture quality from innovative JVC technology within GY-HD200B/250
Horizontal resolution and signal-to-noise ratio have been
enhanced, making the already high ProHD picture
quality even better. Together with ProHD’s superior
colour reproduction, these improvements ensure true
professional quality HD imaging. These are JVC’s key
technology innovations.
 14-bit A/D converter
To improve both the S/N ratio and the horizontal resolution, a new 14-bit A/D converter was specially developed by JVC to prevent signal
deterioration and to generate a fourfold increase in gradations.
 Wideband front end processing
The ProHD camcorder uses a wideband analogue front end to process its CCD sampling via the 14-bit A/D converter. This further
improves the S/N ratio and horizontal resolution by optimising the CCD drive circuitry. The new LVDS (Low Voltage Differential Signal)
interface minimises any other possible signal degradation and so contributes to the improved S/N ratio.
 Newly-developed pixel converter
To enable 720p/50 recording, a new super encoder and a new pixel converter were developed, incorporating an adaptive filter which
optimises the scalar performance of cross-converted signals, including 1080i. The resultant effects are increased resolution and reduced
aliasing. Objects thus have much more natural looking edges and images are therefore extremely lifelike in appearance.

GY-HD250 ProHD Compact Shoulder Camcorder
Professional specifications
True 24p recording
The GY-HD250 is a professional high-definition camcorder featuring
real HD 24p recording capability — previously available on only the
most expensive HD cameras. Ideal for DVD production, HD
progressive 24-frame-per-second recording makes it possible to shoot
images with film-like quality and smooth motion. Once recorded, those
images can easily be transferred without frame rate conversion to 16
mm or 35 mm film with full HD fidelity.
ProHD’s outstanding image quality is supported by a wide range of
powerful features including an image inverse function that cancels
image reversal (reversal of top/bottom and left/right) and a Film out
mode function that automatically adjusts the gamma curve and color
matrix to give images a filmic look.
Three preset gammas (Standard, Cinema for a film-like setting and Film
out for the optimal imagery of a film camera) are available to choose
from depending on the purpose. Combined, these features make this
camcorder ideal for digital film productions.
Interchangeable HD lenses
The GY-HD250 features a standard professional 1/3" bayonet lens
mount, giving you the ability to use a variety of other professional HD
lenses. In addition to the standard detachable 16x servo Fujinon lens, a
wide range of options are available, including a 13x (3.5 mm) wide
zoom lens, 18x Fujinon zoom lens, 20x Canon zoom lens, a wide
angle converter for the standard 16x lens, and adapters that allow 1/2"
and 2/3" bayonet mount lenses to be used.
And when you add film lens mount adapter to the 1/3" bayonet mount,
you can even mount 16mm film camera lenses on the GY-HD250,
greatly expanding your production lens options.
3-CCD camera system with 720p HD CCDs
The GY-HD250 uses three 1/3” high definition CCD image sensors. Each
array has a pixel resolution of 1280 x 720 and uses a micro lens system.
Since this native resolution matches that of most HDTV displays, the
need for image scaling is eliminated, further enhancing the quality of the
recorded images. Other advantages of these CCDs include sophisticated
circuitry that virtually eliminates lag and image burn.
Uncompressed 720/60p live signal output
In addition to providing superior quality HD recording in the HDV format,
the GY-HD250 can capture and output both digital and analog HD
signals at 60 frames per second. Ideal for live broadcasting, the
uncompressed full-resolution signal (either 720p or converted 1080/60i)
can be output via the built-in HD-SDI and component analog terminals,
providing an ideal feed to a video server, HD switcher or microwave link.

Compact shoulder mount design
JVC’s ProHD camcorders are the only professional HD camcorders to
feature a compact shoulder mount design. Like its predecessors, the
GY-HD250 offers excellent mobility and enhanced usability, while its
flexible range of ergonomic adjustments ensures that camera operators,
regardless of stature or physique, can support the camcorder steadily
and, above all, comfortably.
Professional functions and switch layout
In addition to the Full Auto Shooting to handle difficult or variable
lighting environments, the GY-HD250 is equipped with an array of
functions that give professionals creative flexibility. These include,
amongst others, zebra, gain, white balance and full shutter control.
Also, the GY-HD250’s switches have been positioned where
professional camera operators can expect them. This helps make
shooting more intuitive, precise, easy, and error-free, because the
learning process is minimized dramatically, making the GY-HD250 the
ideal camera for any assignment.
Detachable 230,000-pixel LCD
color viewfinder
The viewfinder’s eyepiece can be
moved backwards and forwards and
can also be adjusted laterally for left
or right eye shooting, enabling it to fit
the operator comfortably. JVC’s own
proprietary and patented Focus
Assist control ensures fast and easy
focusing. To make focusing even
easier, a black and white mode is
available. Stronger contrast and
reduced color noise make
visualization and composition easier
in this mode and put less strain on your eyes so you can shoot for
longer periods. You can also keep using the viewfinder even when using
the LCD display. When not required, the viewfinder may be detached.
3.5" LCD display panel*
This 250,000-pixel 3.5" color TFT LCD monitor provides a high-
resolution image during shooting and playback. JVC’s own developed
Focus Assist control (see this page) ensures fast and easy focusing. A
push button selects three display
modes:
1. Video only
2. Video images with text information
overlay including time, status, mode
and other data are shown on the
screen.
3. Only information such as time,
status, mode, time code, audio
levels and other data is shown on
the screen. When the LCD display
panel is in this mode, the viewfinder
can also be used.
Various audio-related functions
When color bars are output, an audio reference level (test tone) can
also be output if required. This is set via the menu. The audio reference
level can be set at -12 dB or -20 dB as required. To minimize
extraneous noise picked up by the microphone, a "wind cut" function
is provided.
Genlock
This camcorder has genlock input capability for synchronization and
time code input/output, making multi-camera shooting possible.
For synchronization, BB or VBS signals (SD) and HD tri-level sync
signals (HD) are available to lock to various components, including
external audio recorders, other cameras and switchers. In addition, H
Phase (HD/SD) and SC Phase (SD only) can be adjusted

Versatility and flexibility
Camera settings recorded on SD card
Customized settings can be stored on a standard SD memory card and
loaded into another GY-HD250 or changed on site, as required.
IEEE 1394 interface/HD-SDI output interface
A convenient IEEE 1394 interface allows easy direct connection to NLE
systems or to a PC for capturing, editing and archiving.
An HD-SDI (High Definition Serial Digital Interface) is also provided to
enable transmission of uncompressed digital HD signals via co-axial
cable. Since the HD-SDI interface can use existing SDI (Serial Digital
Interface) cabling, configuring studio applications is greatly simplified.
User-friendly design
Universal ergonomic design
The GY-HD250 has multiple adjustments to provide a comfortable
positioning of the camera, such as a shoulder pad that can be moved
back and forth, a viewfinder with an eyepiece that can be adjusted left
and right as well as back and forth, and a padded audio monitor that
adjusts up & down.
Patented “FOCUS ASSIST” function
A JVC-patented feature, Focus Assist, turns focusing into an easy, fast
and accurate process. When Focus Assist is activated, the picture in
the viewfinder becomes monochrome and all objects which are in focus
take on a color fringe. In addition to the factory default Middle position,
Low and High positions are available. In the Low position, you can limit
the area in focus for more precise focusing. This is particularly helpful
when using the technique of pulling focus. Focus Assist works equally
in the 0.44" viewfinder and the 3.5” LCD panel. There are two Focus
Assist buttons, one for each of handheld and shoulder operation.
Shutter angle display mode
In addition to the conventional second-unit indication for shutter values,
a shutter angle display mode is available. This makes it easy for all
users — including those more familiar with film cameras — to set the
shutter value.
Connect to optional external HDD
The camcorder has a hard disk drive accessory option, DR-HD100,
which connects via the IEEE 1394 port, allowing footage to be edited
immediately without having to wait for data to be transferred.
Interface to GY-HD250 camcorder
The DR-HD100 has been designed specifically to interface with the GY-HD250
camcorder via IEEE 1394. Interlocked to the camcorder’s record trigger, HD and
SD images can be recorded together with audio and time code. It can be
powered by either a built-in rechargeable or external battery. The DR-HD100 is
supplied with its own cradle, from which it can be detached easily. Optional
brackets are available for mounting the HDD recorder to the rear of the
camcorder.
Compatibility with NLE systems for HDV and DV editing
DTETM technology permits the DR-HD100 recordings in HDV and DV to be set to
the NLE’s native file format. This means that no time is lost due to the lengthy
processes of file transfer and conversion. The
DR-HD100 can be used with most popular editing applications from Adobe,
Apple, Avid, Canopus and many more*. As new application support is released,
the DR-HD100 can be updated in the field with new system software easily by
connecting the disk drive to a computer.
*NLE Dependent
Integrated with camcorder and disk drive operation
Attached with the GY-HD250, the DR-HD100’s record and record/pause
functions are controlled from the camcorder. Time code generated by the
camcorder is recorded to files on the DR-HD100, and recorder status and other
information can appear in both the viewfinder or LCD display.
Long record times
This hard disk drive option extends uninterrupted record time by many hours. For
example, a 100GB FireWire drive can store 8 hours of DV video and 10 hours of
HDV video. It is also possible to daisy chain up to four external drives of different
capacities to the DR-HD100, enabling uninterrupted recording of extremely long
duration.
LCD display and playback modes
The DR-HD100 features a detailed LCD that displays the system mode, time code
and disk space remaining. Video clips can be reviewed in the viewfinder, LCD panel
or external monitor, by using DR-HD100’s playback mode. Functions include record,
play, pause, stop, forward index, back index and multi speed fast forward and
rewind.
