  The video's author might be overstating it by calling it a "disaster" as there is no clear knockout blow.
  Nevertheless, white is clearly better, and the attack will continue with best play, but it requires accuracy or the extra piece may tell the final tale. White will remain down a piece for two pawns, and will probably win a third in the near future due to the indefensible black king. Here is a couple of sample lines, but since neither side is forced, there are many other possibilities.
