Hypotheses
Objects in motion, captured on a long exposure
Most often this artifact is called skayfish if the lens gets a passing bird or insect. It is based on the discrepancy between the speed of the video and the frequency of the flapping of insect wings. Essentially, each video drops a few strokes of the wings of an insect, which when viewed looks like "arrow", provided with long protuberances. The motion of the insect by its translucent body seems to "boom" and vibration of the wings give the appearance of bumps.
