In this one he says at 4:35 that "the solution to our paradox" is that while the doors are able to close simultaneously in the barn's frame with the pole inside, in the pole's frame the door closings are not simultaneous. After actually calculating the times in the pole frame using the LT, he says at 6:45 "Just think about what this means: the time that the back door closes is significantly before the front door closes. In other words, as the barn is moving towards the pole, the back door closes momentarily and then opens up immediately after. And when the back of the pole enters the barn the front door closes. So the closing of the doors that occurred simultaneously in one frame of reference does not occur simultaneously in the other frame of reference, and our paradox is resolved."
