Wind Noise Reduction G button ➜ 1 movie shooting menu Select On to enable the low-cut filter for the built-in microphone (optional stereo microphones are unaffected), reducing noise produced by wind blowing over the microphone (note that other sounds may also be affected). Wind-noise reduction for optional stereo microphones that support this feature can be enabled or disabled using microphone controls. High ISO NR G button ➜ 1 movie shooting menu Reduce "noise" (randomly-spaced bright pixels) in movies recorded at high ISO sensitivities (0 316). Flicker Reduction G button ➜ 1 movie shooting menu Reduce flicker and banding when shooting under fluorescent or mercury-vapor lighting during live view or movie recording. Choose Auto to allow the camera to automatically choose the correct frequency, or manually match the frequency to that of the local AC power supply. D Flicker Reduction in the Movie Shooting Menu If Auto fails to produce the desired results and you are unsure as to the frequency of the local power supply, test both the 50 and 60 Hz 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 try choosing a smaller aperture (higher f-number). To prevent flicker, select mode M and choose a shutter speed adapted to the frequency of the local power supply: 1/125 s, 1/60 s, or 1/30 s for 60 Hz; 1/100 s, 1/50 s, or 1/25 s for 50 Hz. Electronic VR G button ➜ 1 movie shooting menu U Choose whether to enable electronic vibration reduction in movie mode. 322
