Bit rate setting and recording time
a) In HQ mode or LP mode, as a result of MPEG2 compression, the recording
time varies depending on the volume of the generated compressed image
data, with the above figures as a minimum. For example, in material with
little movement, the recording time may be significantly longer than
shown above.

Adjusting the Black Balance/White
Balance
To ensure excellent image quality when using this
camcorder, conditions may require that both the black
balance and the white balance be adjusted.
If the black balance or white balance adjustment is started,
messages that report on the progress and results are
displayed on the viewfinder screen.
Black balance and white balance adjustment values that
are automatically set by the camcorder and the various
settings are stored in the camcorder memory and retained
even when the power is turned off.
To adjust the black balance
The black balance will require adjustment in the following
cases.
• When the camcorder is used for the first time
• When the camcorder has not been used for a long time
• When the camcorder is used under conditions in which
the surrounding temperature has changed greatly
• When the GAIN switch (L/M/H) values have been
changed on the GAIN SW page of the OPERATION
menu
It is not usually necessary to adjust the black balance when
using the camcorder after it has been off.
In automatic black balance mode, adjustments are
performed in the following order: clamp level, black set,
and black balance.
1
Power the camcorder on, and set the OUTPUT/DCC
switch to CAM.
2
Push the AUTO W/B BAL switch to BLK and release
the switch.
The switch returns to the center position, and the
adjustment is executed.
During adjustment, the following message is displayed
on the viewfinder screen.
The black balance adjustment ends in a few seconds
with the message “ABB: OK” and the adjustment
value is automatically stored in memory.
• During the black balance adjustment, the iris is
automatically closed.
• During the black balance adjustment, the gain selection
circuit is automatically activated so you may see
flickering on the viewfinder screen, but this is not a
malfunction.
