Advanced Operations

Recording Shot Marks
On this camcorder, two types of shot marks
are available. You can record them at user-
specified positions to make it easier for editors
to cue up those positions.
The maximum number of shot marks per clip
is 999.
You can also use the Thumbnail menu to add and delete
shot marks in clips. For details, see "Adding/Deleting
Essence Marks in Clips" (page 83).
To record shot marks, turn on an assignable
switch assigned with the Shot Mark 1 or Shot
Mark 2 function.
When a shot mark is recorded, a "Shot Mark
1" or "Shot Mark 2" indication appears in the
viewfinder for about three seconds near the
timecode indicator.
[Note]
An SD card inserted in an SxS card slot using the
MEAD-SD02 Media Adaptor (option) cannot be used for
recording.
Setting Clip Flags
To make it easier for editors to select good
clips, you can set clip flags in recorded clips.
Clip flags are set in the Thumbnail menu.
For details, see "Adding Clip Flags to Clips"
(page 83) and "Deleting a Clip Flag"
(page 83).
[Note]
An SD card inserted in an SxS card slot using the
MEAD-SD02 Media Adaptor (option) cannot be used for
recording.
Recording Retroactive Images
(Picture Cache Rec Function)
The camcorder always maintains a cache
of video and audio data for a set interval
(maximum of 15 seconds) in internal storage
memory when shooting, allowing you to
record several seconds of footage before the
start of recording.
For details about the video formats supported
for this function, see "Special Recording
Support by Recording Format" (page 161).
To start recording in Picture Cache Rec mode,
Picture Cache Rec mode and the storage time
of images in memory (Picture Cache Rec time)
must be set beforehand in the Operation
menu.
When recording is started, the duration of
footage that can be recorded retroactively is
determined by the Picture Cache Rec time. The
duration that can be recorded retroactively
may be reduced in some circumstances, as
described in
[Notes]
below.
[Notes]
ˎ The storage of video in memory starts when Picture
ˎ
Cache Rec mode is selected. However, if recording
is started immediately after selecting this mode,
a portion of the images shot immediately prior
to selecting Picture Cache Rec mode will not be
recorded.
ˎ Images are not stored in memory during playback,
ˎ
recording review, or thumbnail display, so recording of
images during these periods is not supported.
Setting the Picture Cache Rec time
1
Select Operation >Rec Function >Picture
Cache Rec in the setup menu.
2
Turn the MENU knob to select [On], then
press the knob.
3
Select Operation >Rec Function > Cache
Rec Time in the setup menu.
4
Turn the MENU knob to select the Picture
Cache Rec time setting, then press the
knob.
The options will vary depending on the
recording format and system frequency
settings. See "Picture Cache Rec Mode
Settings" (page 162) in the Appendix.
Once Picture Cache Rec mode is selected, it is
maintained until the settings are changed.
Alternatively, instead of performing steps
2
and
, you can also select Picture Cache Rec
mode using an assignable switch (page 120)
which has been assigned with the Picture
Cache Rec function.
[Notes]
ˎ With the exception of some functions
ˎ
a)
, only one
special recording function, such as Picture Cache Rec,
can be used at any one time.
ˎ With the exception of some functions
, if another
ˎ
a)
special recording mode is enabled while Picture
Cache Rec is in use, Picture Cache Rec is automatically
released.
ˎ Changing system settings, such as the video format,
ˎ
clears all images stored in memory. Consequently,
images shot just before changing settings cannot
be recorded, if recording is started immediately
after changing settings. Picture Cache Rec mode is
automatically released.
ˎ The Picture Cache Rec time cannot be set during
ˎ
recording.
a) Picture Cache Rec is also supported in 1-slot Simul
Rec mode.
Starting Picture Cache Rec recording
Shoot as described in "Basic Operations"
(page 44).
When recording starts, the "Cache"
indication in the viewfinder changes to the
"Rec" indication. The TALLY indicators and
the tally indicator on the front panel of the
viewfinder light as they do during normal
recording.
To exit, stop the recording.
Canceling Picture Cache Rec mode
In recording standby mode, set Operation
>Rec Function >Picture Cache Rec in the setup
menu to Off.
Device operation when recording in
Picture Cache Rec mode
1
The recording procedure is essentially the
same, except for the following points where
operation varies from normal.
ˎ If recording is started while accessing media,
ˎ
the actual start point of recording may be
delayed even longer than the set Picture
Cache Rec time. The delay increases with
the number of recorded clips, so stopping
recording and quickly restarting recording
should be avoided in Picture Cache Rec
mode.
ˎ Regardless of the setting of the F-RUN/
ˎ
SET/R-RUN switch, the camcorder operates
in F-RUN mode.
ˎ In Picture Cache Rec mode, time data
ˎ
cannot be set by switching the F-RUN/
SET/R-RUN switch to SET.
To set time data, first stop Picture Cache Rec
mode.
ˎ If the remaining recording time of the media
ˎ
in the currently selected slot is shorter than
the Picture Cache Rec time, images are
recorded to the media (if there is sufficient
remaining recording time) in the non-
selected slot.
However, images are not recorded if there is
no media in the non-selected slot or if the
media in the slot has insufficient remaining
recording time. (A message notifying you
