It's not really worth the time to watch... basically he does a backward chicken dance ending on the ropes like a spider; his opponent is pissed off, he's like "c'mon, cant be real"; you shouldn't even need it, all the protection in 4 years as a professional is more than enough to know wilder's chin.
Khan and Price have 2 of the worst Chins in the sport. Why do people get so upset when people talk about Chins? Glass Jaws exist. Khan and Price have one. Talking about Punch Resistance is no different than talking about a fighters Power, Speed, Stamina, etc. It is an attribute. A Chin is THE most important attribute a fighter can have.
