Ambient light conditions as well as the situation you plan to film are the major considerations. In general, it is better to record at 30 frames per second in the poorest light conditions (cloudy, dark, inside). In this mode, the camera has more time to render individual frames. Whereas in brighter weather, or should you need to record rapid movement, a mode with 60 or more frames per second should be considered. When filming within Europe, it is also necessary to set a frequency of 50 Hz.
