Recording Shot Marks

On this camcorder, two types of shot marks are
available in HD mode. You can record them at
user-specified positions to make it easier for
editors to cue up those positions.
You can record up to 127 shot marks per clip.
Note
Shot marks cannot be recorded in SD mode.
You can also use the THUMBNAIL menu to add and
delete shot marks in clips. For details, see "Adding
and Deleting Shot Marks (UDF and FAT-HD Mode
Only)" (page 102).
To record shot marks
Do one of the following.
• Turn on an assignable switch to which Shot
Mark 1 or Shot Mark 2 has been assigned (see
page 148).
• If Lens RET has been assigned to the RET
button on the lens, operate as follows.
To record shot mark 1: Press the RET button
once.
To record shot mark 2: Press the RET button
twice in quick succession.
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 indication.

Setting OK Marks

To make it easier for editors to select good clips,
you can set OK marks in clips recorded in HD
mode.
Notes
• OK marks cannot be set in SD mode.
• OK marks cannot be set or deleted during recording or
playback.
To add/delete OK marks
You can also use the THUMBNAIL menu to add
and delete OK marks in previously recorded clips.
For details, see "Adding/Deleting the OK Mark
(FAT-HD Mode Only)" (page 99).
Starting to Record from Pre-
stored Video (Picture Cache
Function)
The camcorder is equipped with enough internal
memory to pre-store up to 15 seconds of video
and audio data in a picture cache. This allows you
to begin recording a specified number of seconds
in advance of the time when you press a recording
start button.
Selecting picture cache mode and setting
the picture cache time
Before recording in picture cache mode, you need
to perform the "Picture Cache Rec" and "P.
Cache Rec Time" settings in the "OPERATION"
menu (see page 111).
You can also select picture cache mode by using
an assignable switch to which the Picture Cache
function has been assigned (see page 148).
The picture cache time determines how far in
advance you can start recording, counting back in
seconds from the operation that starts recording.
Note that it may not be possible to start this far in
advance in the special cases explained in the
following notes.
Notes
• Storage of picture data to memory begins when you
select picture cache mode. Therefore, if you start
recording immediately after selecting picture cache
mode, the picture data from before the selection is not
recorded.
• No data is recorded to picture cache memory during
playback or recording review and display of
thumbnails. It is not possible to record picture data
from the time you were conducting playback or a
recording review.
• Picture cache recording is not possible in Frame Rec,
Interval Rec, and Slow & Quick Motion mode. The
camcorder exits Frame Rec, Interval Rec, or Slow &
Quick Motion mode whenever you select picture cache
mode. The camcorder exits picture cache mode
automatically whenever you select Frame Rec,
Interval Rec, or Slow & Quick Motion mode.
• The data stored in picture cache memory is cleared
when you change the system settings, for example by
