General Movie Recording 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
recording. 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 recording 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 recording 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.
