Picture cache mode and picture cache
time settings
To start recording in picture cache mode, picture
cache mode and the storage time of images in
memory (picture cache time) must be set
beforehand in the Operation menu.
When recording is started, the duration of footage
that can be recorded retroactively is determined
by the picture cache time. The duration that can
be recorded retroactively may be reduced in the
following circumstances.
Notes
• The storage of video in memory starts when picture
cache mode is selected. However, if recording is
started immediately after selecting this mode, a portion
of the images shot immediately prior to selecting
picture cache mode will not be recorded.
• Images are not stored in memory during playback,
recording review, or thumbnail display, so picture
cache recording of images during these periods is not
supported.
To set picture cache mode and the picture cache
time
1
Select Operation >Rec Function
>Picture Cache Rec in the setup menu.
2
Turn the MENU knob to select [On],
then press the knob.
3
Select Operation >Rec Function
>Cache Rec Time in the setup menu.
4
Turn the MENU knob to select the
picture cache time setting, then press
the knob.
0 to 2, 2 to 4, 4 to 6, 6 to 8, 8 to 10, 10 to 12,
12 to 14, or 13 to 15 seconds can be selected.
Once picture cache mode is selected, it is
maintained until the settings are changed.
Alternatively, instead of performing steps
2
, you can also select picture cache mode using an
assignable switch (see page 163) which has been
assigned with the Picture Cache function.
Notes
• Only one special recording function, such as picture
cache recording, can be used at any one time.
If another special recording mode is enabled while
picture cache recording is in use, picture cache
recording is automatically released.
• Changing system settings, such as the video format,
clears all images stored in memory. Consequently,
images shot just before changing settings cannot be
recorded, if recording is started immediately after
changing settings. Picture cache mode is automatically
released.
• The picture cache time cannot be set during recording.
Device operation when recording in picture
cache mode
The recording procedure is essentially the same,
except for the following points where operation
varies from normal.
• If recording is started while accessing media,
the actual start point of recording may be
delayed even longer than the set picture cache
time. The delay increases with the number of
recorded clips, so stopping recording and
quickly restarting recording should be avoided
in picture cache mode.
• Regardless of the setting of the F-RUN/SET/R-
RUN switch, the camcorder operates in F-RUN
mode.
• In picture cache mode, time data cannot be set
by switching the F-RUN/SET/R-RUN switch to
SET.
To set time data, first stop picture cache mode.
• If the remaining recording time of the media in
the currently selected slot is shorter than the
picture cache time, images are recorded to the
media (if there is sufficient remaining recording
time) in the non-selected slot.
However, images are not recorded if there is no
media in the non-selected slot or if the media in
the slot has insufficient remaining recording
time. (A message notifying you that there is
insufficient remaining recording time will
appear on the viewfinder screen.)
• Shot marks are not recorded, even if the shot
marks are set before the recording start
operation.
If the camcorder is turned off during recording
• If the POWER switch on the camcorder is set to
the OFF position, the media is accessed for
1
and
several seconds to record the images stored in
