General Movie Shooting Cautions
Recording and Image Quality
o
If you use a card with a slow writing speed, an
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 (1) becomes full, movie shooting will
stop automatically.
o
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.
o
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.
o
If the card’s writing speed is slow (due to fragmentation) and the indicator
appears, formatting the card may make the writing speed faster.
