Must have been some sort of technical issue that needed fixing because it's evident they go to "commercial break" right around the 8m mark there's a blip and Professor Marks, who started with a light gray type sweater, is now wearing a dark blue sweatshirt, and the crinkling sound has disappeared.
What is the background noise? It's very distracting.

Someone else said that the zipper on his sweater was rubbing up against the microphone. I guess that explains why he changed his sweater.
