Panasonic NV-DS30A User Manual

ª Focus

The Auto Focus System automatically moves 
forward and backward the focusing lens inside the 
Movie Camera to bring the subject into focus so that 
the subject can be seen clearly.
However, the Auto Focus System does not function 
properly for the following subjects or under the 
following recording conditions.
Please use the Manual Focus Mode instead.
1) Recording a subject whose one end is 

located closer to the Movie Camera and the 
other end farther away from it
≥Because Auto Focus makes adjustments at 

the centre of an image, it may be impossible to 
focus on a subject that is located in both 
foreground and background.

glass
≥Because the focus is on the dirty glass, the 

subject behind the glass will not be focused.

≥Because the light information that comes 

through the lens decreases considerably, the 
Movie Camera cannot focus correctly.

objects with glossy surfaces or by highly 
reflective objects
≥Because the Movie Camera focuses on the 

objects with glossy surfaces or on highly 
reflective objects, the recording subject may 
become blurry.

≥Because the focus lens inside moves 

mechanically, it cannot keep up with the fast-
moving subject.

≥Because the Movie Camera achieves focus 

based upon the vertical lines of an image, a 
subject with little contrast, such as a white 
wall, may become blurry.

ª White Balance Adjustment

Depending on the type of light source, the colours 
recorded by the Movie Camera may be affected. In 
some cases, images may be recorded with bluish or 
reddish hue. To minimize the effect of light on the 
subject’s colour, what is called White Balance 
Adjustment becomes necessary.

White Balance Adjustment recognizes the colour of 
light and makes adjustment so that the white colour 
will become pure white.

This Movie Camera stores settings that are optimal 
for several kinds of general light sources. The Movie 
Camera determines the hue of light that it receives 
through the Lens, thereby judging the recording 
condition, and selects the closest hue setting. This 
function is called Automatic White Balance 
Adjustment.
However, since white balance settings for only 
several kinds of light sources are stored, the Auto 
White Balance Function does not operate properly 
when recording occurs under light that is out of the 
range of the setup values.

ª Time Code

Time Code signals are data that indicate time 
measured in hours, minutes, seconds, and frames 
(25 frames per second). If this data is included in a 
recording, an address is assigned to each image on 
the tape.
≥The Time Code is automatically recorded as a part 

of the sub-code at each recording.

≥When a new (previously unrecorded) Cassette is 

inserted, the Time Code automatically starts from 
zero. If a recorded Cassette is inserted, the Time 
Code picks up from the point where the last scene 
was recorded. (In this case, when the Cassette is 
inserted, the zero display [0h00m00s00f] may 
appear, but the Time Code starts from the 
previous value.)

≥The Time Code cannot be reset to zero.
≥Unless the Time Code is continuously recorded 

from the beginning of a tape, accurate editing may 
not be possible. To ensure that the Time Code will 
be recorded with no breaks, we recommend the 
use of the Blank Search Function (

l 32) before 

recording a new scene.

ª Memory Stop Function

The Memory Stop Function is useful for the 
following operations.
Rewinding or fast-forwarding a tape to a desired 
position
