This information does not guarantee all memory card operations.
When shooting movies, use a large-capacity card with a fast writing/reading speed.

ALL-I (I-only): 30MB/sec. or faster

If you use a slow card when shooting movies, the movie might not be recorded properly. Also, if you playback movies on a card having a slow read/write speed, movie might not playback properly.
If you want to shoot still photos while shooting a movie, you will need an even faster card.
