I have a problem with printing and I could not find a reason for it. Damaged parts appear at the bottom of the shapes (as in a video)

The second example is pretty clear cut. Spidy's chin is an overhand, and printers haven't learned yet how to lay down layers in thin air, so you need supports. 

The first one is not clear to me from the angle of the camera but most likely also an overhang that requires supports.

It's a combination of cooling and overhang angles. Rotating the part with the steepest overhangs towards the front of the print so that cooling air hits the surface being printed first. If air has to flow around the part to cool the overhang, the print will suffer.
