If there is no card in the camera, the movie-recording size and movie
shooting remaining time will be displayed in red.
When movie shooting starts, the movie shooting remaining time will
change to the elapsed time.
When < > is displayed in white, it indicates that the Live View image
brightness is close to what the actual movie will look like. If < > is
blinking, it indicates that the Live View image is not being displayed at
the suitable brightness due to low or bright light conditions. However, the
actual movie recorded will reflect the exposure setting.
