Notes on Movie Shooting About the icon and camera's internal temperature increase When you shoot movies continuously for a long period or in high temperatures, the camera's internal temperature may increase and the icon may appear on the screen. Note that if you shoot movies for a long period in high temperatures, the icon will appear earlier. Turn off the camera when not shooting movies. If you shoot movies while the icon is displayed, the image quality of the movies will not be degraded. However, if you shoot still photos while the warning icon is displayed, the image quality of still photos may be degraded. You should stop movie shooting and allow the camera to rest until the camera's internal temperature decreases. If movie shooting continues while the warning icon is displayed, the camera's internal temperature will further increase and movie shooting may stop automatically. Movie shooting will be disabled until the camera's internal temperature decreases. Turn off the camera and allow the camera to rest for a while. Playback and TV connection If the brightness changes during movie shooting, that part might freeze momentarily. If you connect the camera to a TV set with an HDMI cable (p.157) 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.156-157) and shoot a movie, the TV will not output any sound during the shooting. However, the sound will be properly recorded. 128
