Notes On Continuous Movie Recording - Sony ILCE-9 a9 Help Manual

Note
The recordable time of movies varies because the camera is equipped with VBR (Variable Bit-Rate), which automatically adjusts
image quality depending on the shooting scene. When you record a fast-moving subject, the image is clearer but the recordable
time is shorter because more memory is required for recording. The recordable time also varies depending on the shooting
conditions, the subject or the image quality/size settings.
The times shown are recordable times using a Sony memory card.

Notes on continuous movie recording

High-quality movie recording and high-speed continuous shooting require large amounts of power. Therefore, if you
continue to shoot, the temperature inside the camera will rise, especially that of the image sensor. In such cases, the
camera will turn off automatically because the surface of the camera is heated to a high temperature or the high
temperature affects the quality of the images or the internal mechanism of the camera.
The duration of time available for continuous movie recording when the camera records with the default settings after
the power has been turned off for a while is as follows. The values indicate the continuous time from when the
camera starts recording until the camera stops recording.
Ambient temperature: 20°C (68°F)
Continuous recording time for movies (HD): Approx. 29 minutes
Continuous recording time for movies (4K): Approx. 29 minutes

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 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.
When [ File Format] is set to [AVCHD], the file size of movies is limited to approx. 2 GB. If the movie file size
reaches approx. 2 GB during recording, a new movie file will be created automatically.
When [ File Format] is set to [MP4], the file size of movies is limited to approx. 4 GB. If the movie file size
reaches approx. 4 GB during recording, recording will stop automatically.
