Maybe this will be helpful to others: I found that when there is a high contrast between the main subject and the background (e.g. dark-clothed people with a white wall in the background), if the exposure is set to the central-point (as I frequently do when I shoot still images) or to the focal point, then the motion of "focus object" can cause rapid changes of the brightness of the video.
So, it is better to have the exposure set to the full-frame,center-weighted mode (green rectangle). In this case, the brightness doesn't fluctuate widely, when the object is moving (e.g. dancing). I don't know how this applies to K3, as I observed it with a K-5 (and probably K-7).
