for a duration of 5 seconds or less, the video light
does not turn off.
The camcorder exits Interval Rec mode when

again the next time you shoot in Interval Rec
mode.

cache memory of a specified duration when
shooting. The picture cache recording time is
set using Picture Cache Rec >Cache Rec Time
(page 82) in the Project menu.
