IIRC he said before that he was going to shift focus towards shorter videos with a more frequent upload schedule, but then dropped the biggest video he's ever done.
I reckon what might have happened is that this video ended up being a lot more time consuming and bloated than they initially expected it to be, and that shows in the finished product.
It's was a thoroughly cromulent video, not bad at all, but it was a bit indulgent. They could have cut it down and probably got it under an hour if stayed focused on the story instead of adding more material to be funny with.
I feel like the Concordia video, by comparison, covered more of the event in less runtime and did a better job integrating the humor into that coverage.
