Delay as an explanation for this video? I call bull. Videos of the view from the tail camera of a landing A380 are available all over the internet.
No there is a delay in the video. There was one doing the rounds years ago when they were a novelty, showing in daylight what appeared to be a A380 touching down on the piano keys. However if you watched spoilers there was no movement until several seconds later demostrating where the touchdown was on the video. Add to that if all these aircraft were really landing that short they would be wiping out fences, LLZ Antennas and approach lights.
