This is time-lapse photography, so you're combining individual images to make a video i.e. we're in the world we know of still photography, not video.

Around 2minutes 50 you have a sequence with almost nothing lit, no subject, just some street lights. Of course there's noise. The camera is at maximum sensitivity trying to makes something of a dark subject.

If it really bothers you then the classic solution is to use an available-light lens like a 85mm f1.8 prime at full aperture. You might be able to use a lower ISO. But the real solution is - shoot something else.
