MPEG-2
Based Encoding
|
JVC is one of
the original developers of the MPEG-2
compression system. MPEG-2 is an interframe
encoding system that combines multiple
frames of digital picture data into a group
of pictures (GOP). It then removes redundant
information from the GOP resulting in far
greater efficiency than with intraframe
systems, such as DV, that compress every
frame separately. JVC pioneered high
definition MPEG-2 recording with its D-VHS
format used by major motion picture studios
for screening and playback of dailies. JVC's
advanced MPEG-2 codecs are used by major
television networks and satellite providers.
In the GY-HD200U JVC has utilized a highly
efficient MPEG-2 codec that compresses the
full HD resolution without downsizing the
image.

14-Bit
Analog to Digital Converter
|
The new 14-bit
A/D converter produces higher quality
images, producing more accuarte levels of
color, shadow and highlights.
|
24-Frame
Cine-Style Capture and Recording
|
Twenty-four
frames per second progressive acquisition
produces recorded images that have a more
polished, film-like appearance than typical
interlaced video cameras. Virtually all high
end digital cinematography cameras utilize
the 24P system. The GY-HD200U uses three
1/3" native high definition CCDs that
produce a more refined HD look without
scaling. Since the native 24-frame material
is recorded to tape, it is possible to
transfer the recordings to film without
frame rate conversion. Time code is recorded
in the 24P mode, so recordings made with the
GY-HD200U can be edited with film based and
high end digital systems with ease.

60-Frame
Full Progressive Recording
|
Until now the
preeminent capture technique for broadcast
sports, 720p/60, has not been available in
the HDV format. The GY-HD200U ushers in a
new era of HDV recording, providing users
with the ultimate sports and news recording
tool. Capture full-frame goodness 60 times
per second for glass-smooth action shots.
|
PAL-Compatible
|
The GY-HD200U
can output both 25p and 50p for PAL
compatible recording. This added
multi-regional flexibility makes the camera
highly versatile in a wide variety of
applications.
|
Increased
Audio Control
|
Audio
capability has been increased with an audio
limiter in manual mode, a 13-segment audio
level indicator along with manual audio
control within full auto shooting mode (FAS).
Full auto mode can be very helpful in
situations such as news gathering, where
time management is critical. These extra
audio controls give operators more
flexibility when shooting in hostile
shooting conditions.
|
Interchangeable Bayonet Lens
|
The GY-HD200U
includes a bayonet mount 16x Servo Fujinon
lens. Operation is the same as with all
professional lenses with mechanical control
of focus, zoom and iris functions. The
built-in servo zoom and iris functions can
also be used if desired. JVC has developed
and patented a focus assist function that
highlights detail in the viewfinder to aid
with critical detail focusing.

Extensive
User-Adjustable Video Looks
|
Creating a
true cinematic look involves more than just
recording at 24 frames per second. The
camera's gamma, detail and black levels can
be adjusted to the user's preference. When
combined with the correct lens filters and
lighting techniques, film like performance
can be obtained that's tailored to the mood
of the scene. There is even a skin tone
detection feature that automatically reduces
the amount of enhancement in facial areas so
that your subjects will not have a wrinkled,
television-like appearance. All custom
settings can be stored on an inexpensive SD
memory card and transferred to another
camera if desired.

Output
Choices
|
|
The user can
chose between letterbox, squeeze and sidecut
when outputting through the composite
connection. The camera can also output
1080i/60 from any 720p/60 recorded signal
through its component connection in real
time! |
