How do I get rid of flicker or banding in movies recorded with the Nikon D800/D800E?
A number of solutions are available. Before you change anything, make sure the flicker and banding is actually present in the recorded movie and not only during live view. The image shown during live view is not processed by the flicker reduction settings.
First, close the viewfinder eyepiece shutter while using live view and recording video. This one is easy to forget but important.
Second, enable flicker reduction in the menu (wrench, flicker reduction) and try out the different settings.
Third, try to avoid fluorescent, mercury-vapor,
sodium-vapor, or similar lighting. If you can't, adapt the shutter speed and/or fps to the frequency of the local power supply. In most parts of the world this is 50Hz, although in the Americas it is typically 60 Hz. Choose an fps of 30 and a shutter speed of 1/125 s, 1/60 s, or 1/30 s in 60 Hz areas; choose and fps of 25 and a shutter speed of 1/100 s, 1/50 s, or 1/25 s in 50 areas.
Fourth, change the position of the lights or try to stop down the aperture a bit. Flicker or banding is most prominent in overexposed parts of the image.
