Solution

General Movie Recording Precautions

Caution

  • Red Temperature warning red internal temperature warning icon

  • If the camera's internal temperature increases due to prolonged movie recording or under a high ambient temperature, a red Temperature warning red icon will appear.
  • The red Temperature warning red icon indicates that movie recording will soon be terminated automatically. If this happens, you will not be able to shoot again until the camera's internal temperature decreases, so turn off the power and let the camera cool down a while. Note that the time until movie recording stops automatically when the red Temperature warning red icon is displayed varies depending on shooting conditions.
  • Recording a movie at a high temperature for a prolonged period will cause the red Temperature warning red icon to appear earlier. When you are not recording, always turn off the camera.
  • Recording and image quality

  • If the attached lens has an Image Stabilizer and you set the Image Stabilizer switch to ON, the Image Stabilizer will operate at all times even if you do not press the shutter button halfway. The Image Stabilizer consumes battery power and may shorten the total movie recording time depending on the shooting conditions. When the Image Stabilizer is not necessary, such as when using a tripod, it is recommended that you set the Image Stabilizer switch to OFF.
  • If the brightness changes as you record a movie with auto exposure, the movie may appear to stop momentarily. In this case, record movies with manual exposure.
  • 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 quality may be lower when recording movies under a combination of conditions such as high ISO speeds, high temperatures, low shutter speeds, and low light.
  • Recording movies over an extended period may cause the camera's internal temperature to rise and affect image quality. Turn off the camera when possible if you are not recording movies.
  • If you play back a movie with other devices, image or sound quality may decline or playback may not be possible (even if the devices support MP4 format).
  • If you use a card with a slow writing speed, an indicator may appear on the right of the screen during movie recording. The indicator shows how much data has not yet been written to the card (remaining capacity of the internal buffer memory), and it increases more quickly the slower the card is. If the indicator (1) becomes full, movie recording will stop automatically.

  • If the card has a fast writing speed, the indicator will either not appear or the level (if displayed) will hardly go upward. First, record a few test movies to see if the card can write fast enough.
  • If the indicator indicates that the card is full and movie recording stops automatically, the sound near the end of the movie may not be recorded properly.
  • If the card's writing speed is slow (due to fragmentation) and the indicator appears, formatting the card may make the writing speed faster.
  • Audio restrictions

  • Note that the following restrictions apply to audio in movie recording.

    • Sound will not be recorded for approx. the last two frames.
    • When you play back movies in Windows, movie images and sound may become slightly out of synchronization.
