• The recording time may differ depending on shooting conditions and the memory
card used.
• When is indicated, stop recording the movie. The temperature inside the camera
has increased to an unacceptable level.
• For details on movie playback, see page 60.
• It requires a lot of power to perform high quality movie recording or continuous
shooting using the image sensor. Therefore, if you continue to shoot, the temperature
inside the camera will rise, especially that of the image sensor. In such cases, the
camera turns off automatically since higher temperatures affect the quality of the
images or affect the internal mechanism of the camera.
• The duration of time available for movie recording is as follows when the camera
starts recording after the power of the camera has been turned off for a while. (The
following values indicate the continuous time from when the camera starts recording
until the camera stops recording.)
• The duration of time available for movie recording varies with the temperature or
condition of the camera before you start recording. If you frequently recompose or
shoot images after the power is turned on, the temperature inside the camera will rise
and the recording time available will be shorter.
• If the camera stops recording due to the temperature, leave it for several minutes
with the power turned off. Start recording after the temperature inside the camera
drops fully.
• If you observe the following points, the recording time will be longer.
– Keep the camera out of direct sunlight.
– Turn the camera off when it is not being used.
• The maximum size of a movie file is about 2 GB. When the file size is about 2 GB,
recording stops automatically when [ File Format] is set to [MP4], and a new
movie file is created automatically when [ File Format] is set to [AVCHD].
• The maximum continuous recording time is 29 minutes.
