Frame Size
The area used for metering exposure, flash level, or auto white balance
when photographs are recorded at a movie frame size of 1920 × 1080
crop (0 67) is not the same as the area in the final photograph, with the
result that optimal results may not be achieved. Take test shots and
check the results in the monitor.
A
Calculating the Length of the Final Movie
The total number of frames in the final movie
can be calculated by dividing the shooting time
by the interval and rounding up. The length of
the final movie can then be calculated by
dividing the number of shots by the frame rate
selected for Frame size/frame rate in movie
shooting menu (0 67). A 48 frame movie
recorded at 1920 × 1080; 24p, for example, will
y
be about two seconds long. The maximum
length for time-lapse movies is 20 minutes.
