Starting to Record from Pre-
stored Video (Picture Cache
Function) (2D mode only)
The camcorder is equipped with enough internal
memory to pre-store up to 15 seconds of video
and audio data in a picture cache. This allows you
to begin recording a specified number of seconds
in advance of the time when you press a recording
start button.
Note
In 3D mode, the picture cache record function cannot be
used.
Selecting picture cache mode and setting
the picture cache time
Before recording in picture cache mode, you must
select picture cache mode and set the picture
cache time (the number of seconds of video and
audio data stored to memory) in the
OPERATION menu.
The picture cache time determines how far in
advance you can start recording, counting back in
seconds from the operation that starts recording.
Note that it may not be possible to start this far in
advance in the special cases explained in the
following notes.
Notes
• Storage of picture data to memory begins when you
select picture cache mode. Therefore, if you start
recording immediately after selecting picture cache
mode, the picture data from before the selection is not
recorded.
• No data is recorded to picture cache memory during
playback or recording review and display of
thumbnails. It is not possible to record picture data
from the time you were conducting playback or a
recording review.
To select picture cache mode and set the picture
cache time
Notes
• Picture cache recording is not possible in Frame Rec,
Interval Rec, and Slow & Quick Motion mode. The
camcorder exits Frame Rec, Interval Rec, or Slow &
Quick Motion mode whenever you select picture cache
mode. The camcorder exits picture cache mode
automatically whenever you select Frame Rec,
Interval Rec, or Slow & Quick Motion mode.
• The data stored in picture cache memory is cleared
when you change the system settings, for example by
selecting a different video format. Picture data from
before the change is not recorded even if you start
recording immediately after the change. The
camcorder exits picture cache mode automatically.
• It is not possible to set the picture cache time during
recording.

Camcorder data handling while recording in
picture cache mode
Recording procedures in picture cache mode are
basically the same as normal recording
procedures. However, note the following
differences with respect to how the camcorder
handles video, time, and output data.
• If you start recording while the media is being
accessed, the start point of the video that is
actually recorded may be later than the
currently specified picture cache time. Because
the delay increases as the number of recorded
clips increases, you should avoid rapid start-
and-stop recording operations in picture cache
mode.
