In movie recording, some functions can be changed with the movie menu (p. 66).
Exposure, focus, and camera sensitivity are automatic. Both the wide focus frames and
the spot focus area can be selected. Quick View can be used. The display button
switches between the full display and the live image only. The flash is disabled. When the
red low-battery indicator appears (p. 16), power is insufficient for movie recording.
The optical and digital zoom are active. A4X digital zoom can be used during recording
when the frame rate is set to 15fps.
Depending on the image size and frame rate, the writing speed of the memory card in
use may prematurely end the recording of a movie clip, especially with 320 X 240 size
images at 30 frames per second. Test the card before important events.
NOTES ON MOVIE RECORDING

MOVIE FILE SIZES

If image size or frame rate is changed, the frame counter will display the approximate
number of seconds that can be recorded at that setting on the installed memory card.
One memory card can contain movie clips with differing sizes and frame rates. The total
time that can be stored on a memory card is determined by the size of the card and the
recording rate. The actual file size is determined by the scene; some subjects can be
compressed further than others.
