If the camera turns off by itself after recording movies or when continuous shooting for a short amount of time, check the following:
- Check whether power-save mode is on.If you do not operate the product for a certain period of time, the camera enters power-save mode. Power-save is released by performing operations such as pressing the shutter button halfway. You can change the length of time before the camera enters power-save mode. For details, refer to the manual.
- Check whether same thing happens with another battery pack.If you have several battery packs, try another battery pack. If the same thing does not happen with another battery pack, there may be a malfunction in the battery pack.
If the camera turns off by itself after recording movies or when continuous shooting, please check the following.
When using the camera to record long movie clips or shooting many continuous bursts of still pictures, the temperature inside the camera increases. If the temperature becomes too high, a warning icon may appear and the camera shuts down to protect the circuitry. This is not a failure; the camera simply needs to be turned off for several minutes so it can cool down.
The length of time you allow the camera to cool affects the amount of time you can use it after being turned back on. The longer you allow it to cool, the longer it will take before the internal temperature builds up again. If the camera does not have enough time to cool, the camera will turn off again after a very short period. The cool down time can take up to 10 minutes or longer depending on the camera and environment.
NOTE: If after checking on the suggestions above and the camera still turns off or a temperature warning indicator is showing up, update the firmware of your camera, if possible.
To maximize the available continuous recording time for movies, you can do the following:
- Format the memory card in the camera.
WARNING: There is a risk of data loss. Formatting erases all the data from the memory card. Make sure any pictures or movies you want to keep have been saved to a computer before formatting.
- Avoid exposing the camera to direct sunlight as much as possible.
- Turn off the power when the camera is not in use.
- For DSLR and SLT models, set SteadyShot to Off.
- When you have SteadyShot turned off, using a tripod will help reduce the shakiness of your video.
- For some SLT models the image stabilization is automatically cancelled when recording movies. For this reason it may not always be necessary to turn off SteadyShot during movie recording.
IMPORTANT: The duration of time available for movie recording varies with the temperature or condition of the camera before you start recording. Any time the camera is on, the internal temperature will increase. This includes when you're actually shooting video or still images, and when not actively using the camera, such as when you're recomposing a shot.
NOTE: Capturing video with DSLR and compact cameras is growing in popularity. These cameras are great for recording short movie clips, but are not designed to replace the non-stop video recording capability of camcorders. All manufacturers in the DSLR and compact digital camera industry have defined a limit of up to 29 minutes, 50 seconds for continuous video recording with these cameras. This limit, however, can often be much shorter depending on the camera. In fact, one brand is limited to 12 minutes and another brand DSLR is limited to 20 minutes. Sony interchangeable lens cameras have an upward limit of 29 minutes, 50 seconds for non-stop video recording. This time will be affected by a number of factors, including ambient temperature, the number of clips being recorded at once, and the amount of time the camera is allowed to cool between clips.
