General Movie Recording Precautions
Guidance Display Before Movie Recording
Guidance may be displayed when the camera starts up, after settings are adjusted, or in other situations.
The guidance warns that the camera may become hot internally if movies are recorded under the current settings, and that if you continue recording, the camera may turn off automatically.
If you will record over an extended period, consider changing the setting indicated by the guidance, so that you can record without the camera displaying guidance.
If you prefer to record without changing the settings, note any warning indicators displayed as you record.
Warning Indicator Display in Movie Recording
A 10-level indicator (1) is displayed during movie recording in case of excessive internal camera temperature.
As the internal temperature rises, the level on the indicator extends to the right. How fast the level increases will depend on shooting conditions. Levels 1–7 are marked in white, but once the temperature reaches level 8, the color changes.
 flashes in red if you continue recording after the indicator reaches level 9, marked in orange. A flashing icon indicates that the camera will soon turn off automatically.
A message is displayed if you continue to record while the icon is flashing, and the camera automatically turns off.
To keep recording under the same settings, leave the camera off and let it cool down a while. Note that the camera may overheat again after you resume recording.
Warning Icon for Low-Temperature Contact Burns
 is displayed if the camera becomes warm during streaming or during image output to external devices. To avoid low-temperature contact burns at this time, do not touch the camera over an extended period.
- The camera may turn off automatically if communication or an external device connection is lost.
Precautions for movie recording
- Do not point the camera toward an intense light source, such as the sun or an intense artificial light source. Doing so may damage the image sensor or the camera's internal components.
- If you record something that has fine detail, moire or false colors may result.
- If  or  is set and the ISO speed or aperture value changes during movie recording, the white balance may also change.
- If you record a movie under fluorescent or LED lighting, the movie image may flicker.
- Large aperture values may delay or prevent accurate focusing.
- Performing AF during movie recording may cause the following kinds of issues: significant temporary loss of focus, recording of changes in movie brightness, temporary stopping of movie recording, or recording of mechanical lens sounds.
- Avoid covering the built-in microphone with your fingers or other objects.
- Connecting or disconnecting an HDMI cable during movie recording will end recording.
- If necessary, also see General Still Photo Shooting Precautions.
- The camera may become warm during streaming or during image output to external devices. Use the stand or a tripod, or take other measures to avoid handheld recording.
Recording and image quality
- If there is a very bright light source in the image, the bright area may appear black on the screen. Movies are recorded almost exactly as they appear on the screen.
- Image noise (such as dots of light or banding) or irregular colors may occur when shooting at high ISO speeds, high temperatures, slow shutter speeds, or under low light. Movies are recorded almost exactly as they appear on the screen.
- Video and audio quality of recorded movies may be worse on other devices, and playback may not be possible, even if the devices support MP4 formats.
Notes for movie recording
- Each time you record a movie, a new movie file is created on the card.
- With some cards, a new file is created each time the file size exceeds approx. 4 GB.
- Field of view (coverage) is approx. 100%.
- Most external microphones equipped with a 3.5 mm mini-plug can be used.
- Any connected external microphone is used instead of the built-in microphone.
