By shooting with a frame rate that differs from
the playback frame rate, you can obtain slow and
quick motion effects that are smoother than low-
speed or high-speed playback of content recorded
at the normal frame rate.
Setting Slow & Quick Motion
1
Select Operation >Rec Function >Slow & Quick
Motion in the setup menu.
2
Turn the MENU knob to select [On], then press
the knob.
Slow & Quick Motion starts, and "S&Q
appears in the recording status indicator area
in the viewfinder.
Next, set the frame rate.
3
Select Operation >Rec Function >Slow & Quick
Motion >Frame Rate in the setup menu.
4
Turn the MENU knob to select the frame rate,
then press the knob.
When you finish making these settings, the system
frequency and the frame rate appear at the top of
the viewfinder screen. You can change the frame
rate while viewing the display in the viewfinder by
turning the MENU knob.
The Slow & Quick Motion mode setting and the
frame rate are retained even after the camcorder is
powered off.
[Notes]
ˎ Only one special recording function, such as Slow & Quick ˎ
Motion, can be used at any one time.
ˎ If another special recording function is enabled while
ˎ
using Slow & Quick Motion, Slow & Quick Motion is
automatically canceled.
ˎ Slow & Quick Motion cannot be set during recording, ˎ
playback, or while the thumbnail screen is displayed.
ˎ Slow & Quick Motion cannot be set if the slow shutter ˎ
function is set.
Starting Slow & Quick Motion recording
Shoot as described in "Basic Operations"
(page 45).
When recording starts, the "S&Q
in the viewfinder changes to the "S&Q 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.
[Note]
It takes longer than normal for recording to stop when the
frame rate is set to a low value (for a slow frame rate).
Stby"
Canceling Slow & Quick Motion mode
With the camcorder in recording standby mode,
set Operation >Rec Function >Slow & Quick in the
setup menu to Off.
Limitations during recording
ˎ Regardless of the setting of the F-RUN/SET/R- ˎ
RUN switch, the advance mode of the internal
timecode generator is always R-RUN.
ˎ Audio cannot be recorded when the recording ˎ
and playback frame rates differ.
ˎ Reviewing the recording (Rec Review) is not ˎ
possible.
ˎ If you change the recording frame rate to a ˎ
value faster than the current shutter speed, the
shutter speed is changed to the slowest value
for which shooting is possible.
Example: If the frame rate is 32 and the shutter
speed is 1/40, and you change the frame rate to
55, then the shutter speed is changed to 1/60.
It is not possible to select a shutter speed that is
slower than the recording frame rate.
ˎ Genlock is not possible. ˎ
Recording with the Clip Continuous
Rec Function
Normally, a clip is created as an independent file
each time that you start and stop recording. But
Stby" indication
this function allows you to start and stop recording
while continuously recording to the same clip, for
as long as the function remains enabled. This is
convenient when you do not want to generate a
large number of short clips, and when you want
to record without worrying about exceeding the
clip limit.
It is still easy to find recording start points, because
a Rec Start essence mark is recorded at the
recording start point each time you start recording.
This function is enabled when the camcorder is set
to any of the following video formats (page 31).
XAVC-I (excluding XAVC-I 3840×2160P)
XAVC-L (excluding XAVC-L 3840×2160P)
MPEG HD 422

function is enabled.
[Notes]
ˎ Only one special recording function, such as Clip ˎ
Continuous Rec, can be used at any one time.
ˎ If another special recording mode is enabled while Clip ˎ
Continuous Rec is in use, for example, the currently
selected mode is automatically released.
You can assign the Clip Continuous Rec on/off
function to one of the ASSIGN. 1/2/3 switches,
ASSIGNABLE 4/5 switches, or the ONLINE button.
For details, see "Assigning Functions to Assignable Switches"
(page 112).
Starting Clip Continuous Rec recording

When recording starts, the "Cont Stby" indication
in the viewfinder changes to "Cont Rec"
indication.
The TALLY indicators and the tally indicator on
the front panel of the viewfinder light as they do
during normal recording.
[Note]
During recording or in recording standby mode (when
"Cont Stby" indication is displayed), if you remove the media,
the battery, or the power source, the media needs to be
restored. It is not possible to restore media on a device other
than this camcorder.

the media.
When "Cont Stby" indication is flashing (once per second),
you can remove the media.
