My graphics were already on ultra. However, after the cutscene, when the screen turns black, I heard movements and sounds of what could be the three walking against objects. I played the scene again and destroyed the wooden boxes that were weirdly placed right in front of the entrance (inside of the longhouse), watched the cutscene without skipping and it worked (graphics still on ultra). Maybe the boxes prevented the script from running through properly.
