Hi, I found a simple solution to this problem when filming in China was to use incandescent lighting and DC light sources. This seem to eliminate the problem. Due to the unstable AC power supply in China, we only experienced the flicker from time to time when using fluorescent lighting sources. The frequency of the AC power seemed to shift at times and the flicker would appear. When we added incandescent light sources, the flicker went away. For one outdoor night scene, we used gas lanterns. Using a generator would be another solution to this problem, as you can select the output voltage and frequency on some models.
