Video flicker in less than optimum illumination

[DonSchaeffer]

I'm big on pushing the limits on illumination in the microscope. Sometimes when I use side illumination, darkening the field, minimizing illumination from below the stage and compensating with my software controls for brightness and contrast, I can still get reasonable still images. in many cases the videos tend to blink and stall. Why do the cameras do that?
