Cache Rec - Sony SRPC-1 Operation Manual

6-3 Cache Rec

The Cache Rec function captures about 100 frames of the
video and audio that the camera is currently shooting (or
about 200 frames in 50P or 59P mode) to the memory of
the HKSR-102 option board. Thus, when you press the
recording start button, the recording starts with the data
stored several seconds before (if the unit is in standby on
mode and SR Motion is not being used).
Notes
• To maximize the Cache Rec effect, it is recommend that
the Cache Rec function be used in standby on mode and
with SR Motion disabled. Though the Cache Rec
function can be used in standby off mode or together
with SR Motion, the unit may be unable to record video
and audio from immediately before you press the
recording start button.
• Cache Rec cannot be used at the same time as Timer
Rec.
The Cache Rec function is disabled by some combinations
of signal formats and target frame frequencies (see the
following table).

Use the procedure in "To start sequential recording
after pausing" (page 69).
• Record after pausing.
Record four seconds or more, and then press the
PAUSE button to pause. The unit starts to save video
