Selection Function
VARIABLE Use for fine adjustment of the video output level.
You can adjust the shutter speed in long exposure
mode or clear scan mode.
In long exposure mode
You can set the shutter speed in units of 1 frame.
For example, if the value is set to 50 frames (about
1.7 seconds in the NTSC format), the total video
signal produced during this set time is output in the
form of one complete frame at intervals of about 1.7
seconds. These pictures, which contain 50 frames of
video information, are much brighter than normal one-
frame images. This mode of setting the shutter speed
is very useful for shooting a poorly illuminated subject
in a dark place.

2
Select the desired shutter speed by pressing the
DATA DOWN button.
Each time you press the DATA DOWN button, the
shutter speed changes in units of 1 frame from 1
FRM through 255 FRM.
