If Auto fails to produce the desired results and you are unsure as to the frequency of the local power supply, test both options and choose the one that produces the best results. Flicker reduction may not produce the desired results if the subject is very bright, in which case you should select mode A or M and choose a smaller aperture (higher f-number) before starting live view. Note that flicker reduction is not available when On is selected for Movie settings
