Recording Time-Lapse Video (Interval Rec Function) - Sony PMW-400K Operating Instructions Manual

If power is lost during recording
• If you set the camcorder's POWER switch to
OFF, the camcorder is powered off
automatically after a few seconds, during which
the media is accessed to record the video and
audio data stored in the camcorder's memory up
to that point.
• If power is lost because the battery was
removed, the DC cable was disconnected, or the
power was turned off on the AC adaptor side,
then the video and audio data stored in memory
is lost. The data stored in memory is not
recorded. Be careful to avoid this when
exchanging the battery.
Recording Time-lapse Video
(Interval Rec Function)
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.
Interval time
Number of frames in one take
A pre-lighting function is available when Interval
Rec is enabled. This function automatically turns
on a video light before recording starts, which
allows you to record pictures under stable light
and color temperature conditions.
Interval Rec settings and shooting
Before recording in Interval Rec mode, you need
to perform the "Interval Rec," "Number of
Frames," "Interval Time," and "Pre-Lighting"
settings in the "OPERATION" menu (see
page 118).
88 Advanced Operations
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.
Notes
• The Interval Rec, Picture Cache Rec, Frame Rec, and
Slow & Quick Motion function cannot be used at the
same time. When you select one of those modes, the
previously selected function is disabled automatically.
• 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.
• Interval Rec settings cannot be changed during
recording.
• Interval Rec is disabled when the following formats
are selected.
- SP 1440/59.94i or SP 1440/50i, when the output
setting is HD and "OPERATION" > "Input/Output"
> "i.LINK I/O" in the setup menu is set to "Enable"
- SP 1440/23.98P (pull-down recording)
- Other than HQ 1920/23.98P or HQ 1280/23.98P,
when the output setting is SD and "OPERATION" >
"Input/Output" > "i.LINK I/O" in the setup menu is
set to "Enable"
• If you want to turn the video light on before the start of
recording, set the camcorder's LIGHT switch to
AUTO. The video light's switch must also be turned
on. When this is done, the video light turns on and off
automatically. However, the video light remains lit
when the time that it is off is five seconds or less.
• If you set the LIGHT switch to MANUAL and turn the
video light's switch on, the video light is always lit. (It
does not go on and off automatically.)
To shoot in Interval Rec mode
Make the settings and preparations described in
"Basic Operations" (page 84), secure the
camcorder so that it does not move, and begin
shooting.
When recording starts, the "Interval" indication
in the viewfinder changes from flashing to lit, and
"INT REC" and "INT STBY" appear
alternatively at the position of the REC
indication. The TALLY indicators and the tally
indicator on the front panel of the viewfinder light
as they do during normal recording.
If you are using the pre-lighting function, the
video light comes on before recording starts.
