Adjusting the white balance and black balance
Adjusting the white balance
3Erect a white pattern at a place with the same
conditions as the source of light illuminating the
subject, zoom in, and shoot the white of the pattern
on the screen.
A white object (such as a white cloth or white wall)
near the subject may be used as a substitute for
the white pattern.
The size of the white object required is shown in
the figure below.
4Adjust the lens aperture.
5Set the AUTO W/B BAL switch to AWB, and then
release it.
The switch returns to the center, and the white
balance is automatically adjusted.

8A message such as the following appears if the
color temperature of the subject is lower than 2300
K or higher than 5600 K.
The downward pointing arrow indicates that the
color temperature is lower than the display
temperature; conversely, the upward pointing
arrow indicates that the it is higher than the display
temperature.

When a zoom lens with an automatic aperture
function is used, aperture hunting may occur.  Adjust
the aperture’s gain control (marked as IG, IS, S, etc.)
provided with the lens.
For details, refer to the operating instructions which
accompany the lens.
Hunting:
The auto iris response is repeated, causing the brightness levels
of the image to become inconsistant.
AWB A OK 2.3K

Adjusting the white balance and black balance
Adjusting the white balance
When the white balance cannot
automatically be adjusted
An error message appears on the viewfinder screen
(when “2” or “3” has been set as the display mode).
When there is no time to adjust the white
balance
Set the WHITE BAL switch to PRST.  The white
balance for the filter is achieved in accordance with
the setting position of the FILTER control (outer).
White balance memories
There are two sets of white balance memories, A and
B.  
When the FILTER INH setting on the CAMERA SW
MODE screen of FILM (CAM) MAIN MENU 4 is ON
(default setting), the number of memories for set A
and set B is limited to one each.  In this case, the
memory contents are not coupled with the filter.
When FILTER INH is set to OFF, the adjustment
values for each filter can be automatically saved in the
memories corresponding to the WHITE BAL switch
settings (A or B).  This unit contains four filters so that
a total of 8 (4a2) adjustment values are saved.
When any of the error messages listed above is
displayed, take the recommended action, and try
adjusting the white balance again.
If the error message persists even after repeated
attempts, consult your dealer.

On rare occasions, AWB cannot be adjusted and a
NG display appears.  In a case like this, adjust AWB
again.

Film tone gamma function
The unit incorporates a total of three gamma curves—
two cine curves (for films/for videos) and the
conventional video gamma curve—and it enables the
curve that best suits the application at hand to be
selected.  
Switching from the film mode to video mode or vice
versa can be accomplished using the CAM MENU
SEL item on the OPTION screen of FILM (CAM)
MAIN MENU 4.
Two gamma curves (for films/for videos) are available
in the film mode.  They can be set by selecting the
CINE GAMMA SEL item on the GAMMA screen of
FILM MAIN MENU 1.
Video mode (VIDEO MENU)
This the optimum mode for playing back the images
recorded on tape using a video component.  The
images are processed using the conventional video
gamma characteristics.
Film mode (FILM MENU)
Two types of film-like images can be achieved in this
mode.
FILM REC (for films: film gamma)
This is the optimum mode for printing the images
recorded on tape onto film and presenting them.
The images are processed using the film-use cine
gamma characteristics developed by Panasonic.
VIDEO REC (for videos: film tone gamma)
Even when playing back images recorded on tape
using a video component, this mode provides a
wide dynamic range, enabling images to be played
back in a mode where the images are more like film
images than the conventional video images.
The images are processed using the video-use cine
gamma characteristics developed by Panasonic.
Switching the frame frequency
This unit allows the frame frequency to be switched to
60.00 Hz or 59.94 Hz to provide support in areas with
different video systems.  The frame frequency can be

Variable frame rate
This camera/VTR enables the frame rate (shooting
speed) to be set from 4 fps to 60 fps.
Since the 720P/59.94 Hz or 720P/60.00 Hz format is
used for recording onto the tape or outputting to the
HD SDI OUT connector, users now have the exciting
opportunity to create a whole new dimension of
moving images with clearer slow-motion images and
blur effects—a world which was hitherto confined to
the field of film production—in their own video
productions.
This unit automatically stores as the tape
management information both the frame rate
information which indicates the shooting speed and
the active frame information which indicates the first
frame where the frame image was switched in the
user’s bit of the sub-code track area (this used to be
the LTC area).  This information is output from the TC
OUT connector and HD SDI OUT connector.  Further,
the active frame information is stored in the least
significant digit of the user’s bit while the frame rate
information is stored in its lower third and fourth digits.
Setting the frame rate
There are two ways in which the frame rate can be
set.
Using menu operations
1Perform the menu operations (pages 84 to 86),
and display the “FRAME MODE” screen of FILM
(CAM) MAIN MENU 2.
2Turn the JOG dial button to move the arrow
(cursor) to the “FRAME RATE” item.
3Press the JOG dial button, and set the desired
frame rate.
Turn the JOG dial button to select the frame rate,
and press the JOG dial button to enter the
selection.
4Press the MENU button to exit the menu
operations.

Variable frame rate

In this unit, the frame rate is set by changing the
storage time of the optical signals sensed by the CCD.
Depending on the frame rate setting, the following
problems may arise.
1White streaks
The dark current of the photodiode that configures
the CCD’s pixels causes defective pixels to arise,
and this results in the appearance of white streaks
on the screen.  This current increases in direct
proportion to the rise in the CCD’s temperature and
storage time in the photodiode.
In short, the white streaks increase in inverse
proportion to the frame rate setting.
When a lower frame rate setting is desired, reduce
the master gain setting and, where possible, avoid
direct sunlight and use the unit in a cool
environment.
2Delayed response time in automatic processing
When the frame rate setting has been lowered, it
takes longer for the unit to perform the automatic
processing (such as auto white balance, flare
compensation, auto knee and auto iris), possibly
giving the user the impression that something is
odd or wrong.
The response time for automatic processes is
particularly slow at a frame rate of 20 fps and
below.  
When the frame rate has been set to 20 fps or
below, it is recommended that the unit be operated
with the automatic processing released.
3Disturbed images
The images may be disturbed for a moment if
scene-to-scene continuity is performed while the
time code is allowed to advance in the rec run
mode when the frame rate is set to 24 fps or 30 fps.
This occurs in order to reset the video signals from
the camera so as to maintain the continuity of the
time code recorded on the tape.
The disturbed images are not recorded on the tape
but they will affect the signals which are output from
the HD SDI OUT connector.
Furthermore, if the time code is allowed to advance
in the free run mode when the frame rate is set to
24 fps or 30 fps, at that instant when the time code
is preset or the time code is locked to the external
signal, the images may be disturbed for a moment.
