General Movie Shooting Cautions
Recording and Image Quality
If you use a card with a slow writing speed, a five-
level indicator may appear on the right of the
screen during movie shooting. It indicates how
much data has not yet been written to the card
(remaining capacity of the internal buffer memory).
The slower the card, the faster the indicator will
climb upward. If the indicator becomes full, movie
shooting will stop automatically.
If the card has a fast writing speed, the indicator will
either not appear or the level (if displayed) will hardly go upward. First,
shoot a few test movies to see if the card can write fast enough.
If the indicator indicates that the card is full and movie shooting stops
automatically, the 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.
Playback and TV Connection
If you connect the camera to a TV set (p.427) and shoot a movie, the TV
set will not output any sound during the shooting. However, the sound
will be properly recorded.
Restrictions on MP4-format Movies
Note that generally, the following restrictions apply to MP4-format movies.
Sound will not be recorded for approx. the last two frames.
When you play back movies on Windows, movie images and sound may
become slightly out of synchronization.
