7-3 Interval Frame Function
Manu Spd2:
The upper or lower limit of the number
of frames shot (FPS)
(This is the lower limit when the upper limit was
set with Manu Spd1. Otherwise it is the upper
limit.)
2
Press the HOME button to return to the HOME screen.
3
With the FUNC button held down, press the SELECT/
ENTER dial twice.
A screen like the following appears, in which you can
check the settings.
4
With the FUNC button held down, press the SELECT/
ENTER dial.
5
Rotate the ADJUST knob or the SELECT/ENTER dial
to vary the number of frames shot.
To temporarily remove the upper and lower limits
With the FUNC button held down, press the SELECT/
ENTER dial again.
7-3 Interval Frame
Function
Even when you use a camera that does not support the
Select FPS function, you can obtain motion effects without
afterimaging by using the Interval Frame function. This
can be selected when you are using a HDC1500 or another
separate camera (BNC) connection. You can obtain
variable-speed motion effects by changing the frame
frequency during recording (Ramp function).
This function extracts frames from video material at a
frame frequency set on this unit, stores them in memory,
and records the stored frames onto tape.
The frame interval of shot frames is set in units of FRM
(frames).
It can be set in steps of 1FRM within the following ranges.
For 4:2:2 formats:
1 to 64FRM
For 4:4:4 formats:
1 to 32FRM
For details on the Ramp function, see 7-3-3 “Using the
Ramp Function” (page 94).
7-3-1 Relation Between the Number
of Frames Shot and the Frame
interval (Outline of Interval
Frame)
To obtain the desired slow or quick motion effects using
the Interval Frame function, you need to set the appropriate
frame interval according to the number of frames shot.
When the camera has shot the material in 24P format (at 24
FPS, or in other words at a system frequency of 24 frames),
and you set the frame interval to 6FRM, then a frame is
extracted once every 6th frame from the 24 frames of video
signals shot by the camera. In other words, 4 frames of
video signals are extracted every second and recorded onto
tape.
When the signals are played back at 24PsF, a quick motion
effect of 6 times normal playback speed is obtained.
The following figure illustrates the operation described
above.
