Even the person on the ground taking the video was screaming for a go around. Obviously way too fast over the threshold but if they'd gone for a missed approach at that point it should have worked out okay. The wings were rocking, probably in an attempt to line up with the runway after only getting visual in the last few seconds. There appears to be an increase in thrust as they enter the airport boundary which could have been the autothrust kicking in to maintain speed, or they may have started to go around and had a change of mind at the last second thinking they could make it, either way it further unstabilised the approach.
The current runway length is given as 2175m which is pretty tight, especially if you aren't correctly lined up and on speed. The PF was trying quite hard to put it onto the ground as well which contributed towards the wing strike.
