On that A380 video - To me it looks like a dangerously short under-shoot and they barely made the end of the runway.
It's a bit hard to see in the video but if you look at the PAPI it seems to show on-slope .... the problem being that the camera is on the top of the tail and that means something like twenty metres off the ground as the wheels touch (It's about 25m on the ground when level, I'm allowing for strut extension and pitch angle)
Since the wheels would normally go over the threshold at around 50' then it means that they must have touched down very close to the end of the runway, if not before.
