Canon EOS Rebel T1i EOS REBEL T1i/EOS 500D Instruction Manual - Page 206

Troubleshooting Guide The camera makes a noise when it is shaken. The built-in flash's pop-up mechanism moves slightly. This is normal. The shutter makes two shooting sounds during Live View shooting. If you use flash or if ISO 3200 or higher is set, the shutter will make two sounds each time you shoot (p.107). The movie shooting terminates by itself. If the card's writing speed is slow, movie shooting may stop automatically. Use an SD Speed Class 6 " " or faster card. To find out the card's read/write speed, see the card manufacturer's Web site. If the movie file size reaches 4 GB or if the movie recording time reaches 29 min. 59 sec., movie shooting will stop automatically. The 1920x1080 movie looks distorted. When shooting movies at 1920x1080 with this camera, only 20 frames are recorded per second (20 fps). Therefore, if there is fast movement in the movie scene, the picture might look distorted. This distortion will be resolved if you shoot at the 1280x720 recording size (p.123). When the movie is played, camera operation noise can be heard. If you operate the camera's dial or lens during movie shooting, the respective operation noise will also be recorded (p.127). 206
