Select either “Weave (Interlace)” (for subjects which move a li\
ttle) or “Bob (Non-Interlace)” (for
subjects which move a lot), according to the range of the movement.
You can obtain high-resolution video if you set “Video Capture Size”\
 to “Large Size”. However
if the subjects move quickly and sharply, you may encounter comb-shaped \
blurs in the video.
“Bob” is more effective for quickly moving subjects.

● Note on shooting images continuously
When taking images of location where the light source gradually changes \
like
shooting outdoor images continuously during day and night, and there is \
little
change in the pictures you are taking, the color of pictures shown may b\
e
different from the actual color.
To reflect the actual color, control the camera such as panning, tilting\
 or
zooming*
1 because it causes a change in the captured images.
*1 With VB-C50FSi and VB-C50Fi, change the zoom position or put a hand ove\
r the lens.
●  Under the conditions where a single-colored object is focused on or sod\
ium
lamp, mercury lamp, or a specific type of fluorescent bulb is used, colo\
r
adjustment may not be made automatically.
