Yes, from that video there is a good likelihood that the puck crossed the line. But, from where the ref is standing, it's virtually impossible for him to actually see the puck in the net. Even less possible for the goal judge to see it. Seriously, you can say all you want that it's obvious that the puck was in the net. That's not the issue. The ref and the goal judge could not see it, and the video evidence, while interesting, is not conclusive, certainly not enough to overturn the original call. You can speculate all you want, but you can not clearly see the puck fully over the goal line at any time prior to the stoppage in play.
