Changing the Aspect Ratio
When recording in standard definition (SD), you can change the aspect ratio of your recording to 16:9 or
4:3.
Set the MODE SELECT switch to SD 16:9 or SD 4:3.
The camcorder’s viewfinder has a 16:9 aspect ratio. If you select the 4:3 aspect ratio, the picture will appear in
the center of the screen with black side panels.
 If you change the position of the MODE SELECT switch while recording, the aspect ratio will not
change immediately. It changes once you pause recording.
 When recording in 4:3, you can attach the optional RC-72 Ratio Converter (0.8x) to achieve the
same angle of view of the 16:9 aspect ratio.
