Sound is not recorded with movies: Microphone off is selected for Movie
settings > Microphone (0 131).
Live view ends unexpectedly or does not start: Live view may end automatically
to prevent damage to the camera’s internal circuits if:
• The ambient temperature is high
• The camera has been used for extended periods in live view or to
record movies
• The camera has been used in continuous release modes for extended
periods
If live view does not start when you attempt to start live view, wait for the
internal circuits to cool and then try again. Note that the camera may feel
warm to the touch, but this does not indicate a malfunction.
Image artifacts appear during live view: “Noise” (randomly-spaced bright
pixels, fog, or lines) and unexpected colors may appear if you zoom in on
the view through the lens (0 32) during live view; in movies, the amount
and distribution of randomly-spaced bright pixels, fog, and bright spots
are affected by frame size and rate (0 131). Randomly-spaced bright
pixels, fog, or bright spots may also arise as a result of increases in the
temperature of the camera’s internal circuits during live view; exit live
view when the camera is not in use.
Flicker or banding appears during live view or movie recording: Choose an option
for Flicker reduction that matches the frequency of the local AC power
supply (0 215).
Bright bands appear during live view or movie recording: A flashing sign, flash, or
other light source with brief duration was used during live view or movie
recording.
Menu item cannot be selected: Some options are not available in all modes.
