[ ] 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 [

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.
