Recording and image quality
If the attached lens has an Image Stabilizer and you set the Image Stabilizer switch
to <
>, the Image Stabilizer will operate at all times even if you do not press the
shutter button halfway. This will consume battery power, and it may reduce the total
movie recording time under some shooting conditions. When the Image Stabilizer
is not necessary, such as when using a tripod, it is recommended that you set the
Image Stabilizer switch to <
>.
If the brightness changes as you record a movie with auto exposure, the movie
may appear to stop momentarily. In this case, record movies with manual
exposure.
If there is a very bright light source in the image, the bright area may appear black
on the screen. Movies are recorded almost exactly as they appear on the screen.
Image quality may be lower when recording movies under a combination of
conditions such as high ISO speeds, high temperatures, low shutter speeds, and
low light.
Recording movies over an extended period may cause the camera’s internal
temperature to rise and affect image quality. Turn off the camera when possible if
you are not recording movies.
Video and audio quality of recorded movies may be worse on other devices, and
playback may not be possible, even if the devices support MP4 formats.
If you use a card with a slow writing speed, an indicator may appear on the right
of the screen during movie recording. The indicator shows how much data has
not yet been written to the card (remaining capacity of the internal buffer
memory), and with slower cards, it increases more quickly. If the indicator (1)
becomes full, movie recording will stop automatically.
With cards that have fast writing speeds, the indicator will not appear, or the level
(if displayed) will not increase much. First, record a few test movies to see if the
card can write fast enough.
If the indicator shows that the card is full, and movie recording stops automatically,
sound near the end of the movie may not be recorded properly.
If the card’s writing speed is slow (due to fragmentation) and the indicator appears,
formatting the card may make the writing speed faster.
Audio restrictions
Note that the following restrictions apply to audio in movie recording.
• Sound will not be recorded for approx. the last two frames.
• When you play back movies in Windows, movie images and sound may
become slightly out of synchronization.
