[ ] icon [ ] may be displayed if repeated movie recording or extended use of Live View display increases the camera's internal temperature. Turn off the camera or take other measures when [ ] is displayed, and wait until the camera cools down. The camera will turn off automatically if you continue recording while [ ] is displayed. The camera may also turn off automatically if you continue using Live View display while [ ] is displayed. Recording and image quality If the attached lens has an Image Stabilizer and you set the Image Stabilizer switch to < >, the Image Stabilizer will operate at all times even if you do not press the shutter button halfway. This will consume battery power, and it may reduce the total movie recording time. When the Image Stabilizer is not necessary, such as when using a tripod, it is recommended that you set the Image Stabilizer switch to < >. 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 noise 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, except in time-lapse movie recording or with Canon Log View Assist. 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. 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 not appear or the level (if displayed) will not increase much. First, record a few test movies to see if the card can write fast enough. If the indicator shows 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. 354
