3-2-5 Starting a Shoot with a Few
Seconds of Pre-Stored Picture Data
(Picture Cache Function: with the
HKDW-703)
By installing an optional HKDW-703 extension board in
the camcorder, the camcorder is able to constantly store a
few seconds (up to 8 seconds) of the most current picture
and sound data in the board’s memory.
As a result, when you press the VTR START button or the
VTR button on the lens, the recording starts with the data
stored a few seconds before.
Setting the Picture Cache time/Picture
Cache mode
To record in Picture Cache mode, you need to turn on
Picture Cache mode and set the picture data storage time
(Picture Cache time) using the USER menu.
The Picture Cache time and VTR SAVE/STBY switch
settings determine the number of seconds of picture data
that will be stored in memory and recorded when you press
the VTR START button or VTR button on the lens.
The following table shows the approximate number of
seconds worth of picture data (counting back from the time
you begin recording) that will be recorded from memory.
However, when changing from SAVE to STBY, or under
the special situations explained in the notes on this page,
the actual amount of data recorded may be shorter.
Picture Cache time setting and recording start point
1) For 50i/25PsF format, you can record about 5 second of picture data stored
in the memory.
• After selecting the Picture Cache mode, immediately
changing the Picture Cache time, or performing
playback or recording review, the picture data stored in
memory before this operation becomes unstable. This
means that when you press the VTR START button or
the VTR button on the lens, the previously stored picture
data will not be recorded.
• During playback or recording review, the picture data is
not stored in the HKDW-703’s memory. Picture data
corresponding to the duration of playback or recording
review will not be in memory and will not be recorded on
tape.
