Using the Movie mode
In Movie mode, you can customize settings to record HD videos of up to 20 minutes 
in length. The camera saves recorded videos as MP4 (H.264) files. This mode is 
available only when you insert a memory card into the camera.
H.264 (MPEG-4 part10/AVC) is a high-compression video format established by 
the international standards organizations ISO-IEC and ITU-T.
If you use memory cards with slow write speeds, the camera may not save videos 
properly. Video recordings may be corrupted or fail to play back correctly.
Memory cards with slow writing speeds will not support high-resolution videos. 
To record high-resolution videos, use memory cards with faster write speeds.
If you use the zoom function when recording a video, the camera may record 
the noise of the zoom operating. To decrease zoom noise, use the Sound Alive 
function. (p. 81)
