When your camera's shutter speed and frame rate don't line up perfectly with the frequency of these pulses, you've got some nasty flickering on your hands. You see, though the light emanating from certain lighting units may appear to be continuous, many bulbs are actually giving off pulses of light. If you've ever encountered flickering, or "banding," in your videos and wondered why it's happening, the reason deals with the interaction between light sources and camera settings. However, this method does leave you with an image that isn't perfectly sharp, so the best thing to do, if you can, is to take certain precautions to avoid flicker altogether. The technique used in the video is awesome for those who may have miscalculated their camera settings, didn't realize there was an incandescent or fluorescent bulb on set, or just simply didn't know flicker even existed. ![]()
