Only when [NTSC/PAL Selector] is set to NTSC.
When using the camera's default settings, continuous shooting is possible for approximately
29 minutes (max.) for each shooting at a temperature of approximately 25°C (77°F).
However, the recording time is approximately 5 minutes when shooting movies in XAVC S
4K or XAVC S HD 120p/100p format.
If the file format is set to MP4 (28M), continuous shooting is possible for approximately 20
minutes for each shooting (limited by file size of 4 GB).
Note
The recordable time of movies varies because the product 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.
Notes on continuous movie recording
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.)
Ambient temperature: 25°C (77°F)
Continuous recording time for movies: About 29 minutes (However, the recording time is about 5
minutes when recording in XAVC S 4K or XAVC S HD 120p/100p format.)
The duration of time available for movie recording varies with the temperature, the
recording format/setting, 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.
When is indicated, stop recording the movie.
If the camera stops recording due to the temperature, leave it for several minutes with the
