Image Artifacts
Flicker, banding, or distortion may be visible in the moni-
tor and in the final movie under fluorescent, mercury va-
por, or sodium lamps, when power aperture is in use, or if
the camera is panned horizontally or an object moves at
high speed through frame. Jagged edges, color fringing,
moiré, and bright spots may also appear. Bright areas or
bands may appear with flashing signs and other intermit-
tent light sources or if the subject is briefly illuminated by
a strobe or other bright, momentary light source. Noise
(randomly-spaced bright pixels, fog, or lines) and unex-
pected colors may be more noticeable if you zoom in on
the view through the lens during live view.
The Flicker reduction option in the movie shooting menu
can be used to reduce flicker under fluorescent, mercury
vapor, or sodium lamps. The desired results may not be
obtained if the subject is very bright, in which case you
should try a smaller aperture (higher f-number).
Ending Recording
If the maximum length is reached, the memory card fills,
the battery runs low, the live view selector is rotated to C,
the lens is removed, or the camera overheats, filming will
end automatically and all footage shot to that point will be
saved. No movie will be recorded if the battery is removed
during filming.
