Notes on Movie Shooting
Camera’s internal temperature increase and image degradation
If the camera’s internal temperature becomes high, the <E> icon may
appear on the screen. When not shooting, turn off the camera.
If you take still photos while the <E> icon is displayed on the screen, the
image quality may be degraded. The image quality of movies is not
affected.
If the <E> icon is displayed and you keep shooting movies until the
camera’s internal temperature rises further, the movie shooting will stop
automatically. If this happens, you will not be able to shoot again until the
camera’s internal temperature decreases. Turn off the power and let the
camera rest for a while.
Playback and TV connection
If the brightness changes during movie shooting, that part might look
momentarily still when you playback the movie.
If you connect the camera to a TV set with an HDMI cable (p.167) and
shoot a movie in [1920x1080] or [1280x720], the movie being shot will
be displayed at a small size on the TV. However, the actual movie will be
properly recorded at the movie recording size that was set.
If you connect the camera to a TV set (p.167, 169) and shoot a movie,
the TV will not output any sound during the shooting. However, the
sound will be properly recorded.
