Recording Video Intermittently
(Interval Rec)
The camcorder’s Interval Rec function allows you
to capture time-lapse video to the camcorder’s
internal memory. This function is an effective way
to shoot slow-moving subjects.
When you start recording, the camcorder
automatically records a specified number of
frames at a specified interval time.
This function is enabled when the camcorder is set
to any of the following video formats (page 69).

ˎ
XAVC-I

When Interval Rec is enabled, the HVL-LBPC
(option) video light automatically turns on before
recording starts, which allows you to record
pictures under stable light and color temperature
conditions (pre-lighting function).
[Notes]

Only one special recording function, such as Interval Rec
recording, can be used at any one time.
ˎ
ˎ
If another special recording mode is enabled while
Interval Rec is in use, Interval Rec is automatically released.

ˎ
Interval Rec mode is automatically released after changing
system settings, such as the video format.

Interval Rec settings cannot be changed during recording
or playback, or when the thumbnail screen is displayed.
To set Interval Rec
Set Interval Rec (page 65) >Setting in the
Recording menu to On, and set Number of Frames
and Interval Time.
If using the HVL-LBPC video light (option), set the
time interval for turning on the video light before
recording starts using Interval Rec >Pre-Lighting in
the Recording menu, as required.

If you want to turn the video light on before the start
of recording, set the video light switch to AUTO. The
video light turns on and off automatically according to
the setting of Video Light Set (page 54) in the Camera
menu.

If the video light is configured so that it will turn off for
a duration of 5 seconds or less, the video light does not
turn off.
The camcorder exits Interval Rec mode when it is
powered off, but the Number of Frames, Interval
Time, and Pre-lighting settings are maintained.
You do not need to set them again the next time
you shoot in Interval Rec mode.

When shooting ends, the video data stored in
memory up to that point is written to the media.

adaptor, then the video and audio data shot
up to that point may be lost (maximum 10
seconds). Care should be exercised when
exchanging the battery.
Recording Cached Pictures (Picture
Cache Rec)
The Picture Cache Rec function allows you
to capture video retroactively when you start
recording and then record it to XQD memory
cards by maintaining an internal cache memory
of a specified duration when shooting. The
picture cache recording time is set using Picture
Cache Rec >Cache Rec Time (page 65) in the
Recording menu.
