Claim:
1. A method for making a digital video, the method comprising: synchronizing one or more light emitting diode (LED) light fixtures to the shutters of one or more digital cameras, wherein the one or more LED light fixtures are dimmable; changing an intensity of the one or more lights while the shutter on each of the one or more cameras is closed; turning on one or more of the lighting fixtures at a predetermined intensity while the camera shutters are closed so that personnel on set perceive light that is constantly on and flicker free; reducing the time in each camera cycle when the shutter is open so there is sufficient time when the shutter is closed to accommodate a lighting transition from the intensity of the lighting while the shutter is open, an anti-flicker lighting pulse, and a lighting transition to the intensity of the lighting when the shutter is next open; defining a plurality of n lighting schemes, each scheme comprising desired intensities of the one or more light fixtures; switching the lighting fixtures sequentially between the lighting schemes in synchronization with the camera shutters at a rate equal to the frame capture rate of the cameras divided by n; and the cameras capturing the plurality of lighting schemes on interleaved video frames during a single video take, wherein every n
