The duration of time available for movie recording varies with the temperature, file format/record setting for movies,
Wi-Fi network environment, 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 (Overheating warning) icon appears, the temperature of the camera has risen.
If the camera stops movie recording due to a high temperature, leave it for some time with the power turned off. Start
recording after the temperature inside the camera drops fully.
If you observe the following points, you will be able to record movies for longer periods of time.
Keep the camera out of direct sunlight.
Turn the camera off when it is not being used.
