Setting the Movie Recording Quality
Cards that Can Record Movies
For details on cards that can record at each level of movie recording
quality, see page 611.
When shooting movies, use a high-capacity card with a writing/reading
speed (as specified in card performance requirements) shown in the
table on page 611 or higher than the standard specification. Test the
card by taking a few movies in the desired quality (p.192 ) and make
sure the card can properly record the movie.
o
Format cards before shooting 4K movies (p.373).
o
If you use a slow-writing card when shooting movies, the movie may not
be recorded properly. Also, if you play back a movie on a card with a
slow reading speed, the movie may not be played back properly.
o
When shooting movies, use high-performance cards with a writing speed
sufficiently higher than the bit rate.
o
When movies cannot be recorded normally, format the card and try
again. If formatting the card does not resolve the problem, refer to the
card manufacturer’s Web site, etc.
o
To obtain better performance with the card, formatting the card with the
camera before shooting movies is recommended (p.373).
o
To check the card’s writing/reading speed, refer to the card
manufacturer’s Web site, etc.
