to the DVCPRO HD product line up. This is the first high
definition production camera that is capable of variable frame
rate at the touch of a button. Individual frame rates may
be selected from: 4-fps to 60-fps in single frame increments.
Frame rates may be changed during recording. Designed as a
high quality production camera, this native 720p camcorder
can be used for 60-fps or the film-like 24-fps acquisition.
When acquiring for 24-fps projects, higher than 24-fps operation
can be processed for slow motion effects while slower than
24-fps operation can be processed to speed up motion. Additionally,
the variable frame rates and related variable shutter speeds
create some very interesting ghost like motion blur effects,
warp speed zoom effects, and long exposure still shots typical
of what one might see in music videos, sci-fi dramas and dream
sequences.
The camera has the capability to emulate film's gradual transfer
function performance (i.e. cinema gamma). This function greatly
increases the camera's usable dynamic range, especially in
traditionally limiting areas such as highlight handling, which
until now was a serious limitation for most HD cameras. "Cine
Gamma" provides the user with a much closer approximation
of film's renowned ability to maintain smooth image tonality
even when gently compressing extreme highlights. Cinematographers
are able through the Cine Gamma feature to control the camera's
gamma transfer function to best optimize control over tonality,
from extreme highlights to the lowest of shadow areas.
The AJ-HDC27F VariCam serves a triple role: 1.) as a 24-fps
camera, 2.) as a standard 60-fps video camera, and 3.) as
a variable frame rate special effects camera.
It
is important to understand that only the camera section operates
at variable frame rates. The VTR and the camera HD-SDI output
operate at a constant 60-fps rate. If you set the camera for
60-fps with no shutter, the exposure time is 1/60th of a second
and each camera frame is recorded once on tape. As soon as
the frame rate becomes lower than 60, exposure time increases
proportionally and redundant frames are recorded on tape.
For example, if the camera operates at 30-fps, each new frame
is recorded twice to ensure 60-fps on tape. 24-fps is a non-evenly-divisible
frame rate and requires the classic 3:2 type pulldown frame
sequence with one frame recorded three times and the next
two times. As you see, this technique generates redundant
frames used to pad the data to maintain a constant 60-fps
on tape including both new frames and redundant (repeated)
frames.
By keeping the VTR frame rate at 60-fps no new DVCPRO HD studio
VTRs or specialized video monitors are necessary. By recording
standard 720p 60, tape can be run through a standard linear
tape based post production chain, yet still deliver "film
look" video. If a linear 24-fps post production process
is required, material can be converted to D-5 HD 1080p 24-fps
by the Panasonic UFC-1800 or other 3rd party products currently
under development. This process works by removing redundant
frames. Various NLE systems now support editing with variable
frame rates acquired with the AJ-HDC27.
• Colorimetry - Standard color is compliant with SMPTE
standards. To achieve a desired "look", an advanced
color correction scheme utilizes a 12-pole color matrix
that allows very specific colors to be set, especially when
critical color matching is vital.
• New Digital Signal Processing (DSP) - Offers a higher
standard of precision color, detail and gamma processing
to ensure optimum picture quality that is repeatable and
transferable to all AJ-HDC27 VariCams.
• Assignable Scene Files - An externally accessible
switch allows for easy access to any of three user-designed
set-ups, each with programmable color, detail, gain and
gamma. (Most commonly these switches are used for gain sets,
leaving other presets in place.) [ L/M/H ]
• Scene Files, Internal Memory - A selection of four
separate camera set-ups -- plus one user standard-reference
file -- are available through user menu access. These set-ups
are stored in camera memory and updated as needed.
• Scene Files, Card Storage - Camera set-ups can also
be saved on a removable SD or Multi-Media Memory Card, allowing
quick memory access to user-designed camera settings to
achieve a particular look for given scenes. Also useful
for matching multiple cameras with the same "look".
Up to eight scenes are saved on this card.
• Simple Cinematic Settings - Provides for superior
versatility in a single camera system when the Film User
Menu is chosen.
• User 1 / User 2 - Two externally accessible, user-assignable
switches provide direct access (on or off) any one of six
operational functions, including Super Gain, Super Black,
Black Stretch, Super Iris, and Audio 1 & 2 (for viewfinder
display).
• Wide Lens Selection - Offers the ability to capture
superb images with a wide selection of lenses including
todays newest HD technology lenses and a large variety of
existing prime lenses.
• White Balance Selection - Select between two programmable
automatic white balance conditions (as set by the user)
and one preset that can be set for either 3200° or 4300°
Kelvin. This feature comes in very handy when moving quickly
between dissimilar ambient lighting conditions. [ Preset/A/B
]
• Wide Range Gain - When shooting in wide-ranging
light-level conditions, a programmable gain switch can be
set to optimize signal levels -- choose from -6 dB to +30
dB in thirteen steps.
• Low Power Consumption - A moderate 32 Watts power
consumption (38 Watts max) means a good battery life can
be realized. Expect about 1.5 hours from a HyTron 100 battery.
The camera runs cool and does not employ a fan, assuring
quiet operation.
• 46 Minutes Record Time - Employing the large DVCPRO
Cassette, a recording time of 46 minutes is possible thanks
to the DVCPRO HD video recording format.
• Three 1.1-Million Pixel IT CCDs - True to high-definition
standards, the Matsushita 720 x 1280 IT CCDs are the key
ingredient in creating rich images.
