Any movement recorded in HD mode is not clear.
HD mode images may appear to move somewhat stiffly compared with SD mode or DV mode images. This is because they are shot at a rate of 30 frames per second compared with the 60 frames per second for the SD or DV mode images. The movie is shot at 24 frames per second, and looks good. So HD mode can have the same feel as a movie material. For smooth movement during video clips, we recommend you minimize rapid-panning or avoid shooting fast-moving subjects. Should you wish to record more natural motion in the picture, we recommend setting a slower shutter speed, or changing the recording mode to SD or DV.
