I still don't think we can conclude that the others landed before the threshold or dangerously close to it.
Most of the A380 drivers on Qrewroom reckon that they've banged it on well short. The spoiler deployment by the 1000' markers was one of the give aways apparently. They take a while to come up on the A380- as the latter video of the A380 landing in Dubai tend to show.

If you can work out at what airport and runway these landings happened at, next time someone flies in you'd probably be able to spot some big, fat, black A380 "elevenses" on the undershoot if they plonked it in short.

Both of them are on 16R at Sydney. And both, as we can compare the daylight video, are very, very short.

A380-800 driver - as you say
there may be more to the story
BUT there are no excuses short of 3 engines out, for an A380 to land before the runway threshold.

Isn't the Dubai landing long?

I know the camera is in the tail giving a false impression of the landing but the touchdown lights appear to have almost passed beneath the leading edge of the wing. This must make it well beyond the usual touch-down point.

Yeah it looks long to me as well. If they're anything like a 747 you plan to touchdown on the 1500' markers.
I was always nervous about landing short in the big jet ....

It's inevitable that there'll be *some* delay before video frames make it to the seat-back displays, probably much greater than the delay pilots see on their MFDs. I don't know much about the A380 entertainment system but the feed may well go via a hard drive on the central server, and the in-seat part of the entertainment system probably buffers some frames ahead of time as well. Even a barely perceptible half-second delay is 120 feet at 140 knots. I don't think it's fair to critique these landings as "short" without having more information about the display lag or having other evidence as to the touchdown point.
I was tending to critique the landings by the very loud crash sound and the cameras going out of control. A380 apologists.....sheesh

I16- Yes, I get a window at the 'blunt' end, which in the A380, is at the front of the aircraft. Some people might call it an ugly looking aircraft, and they wouldn't be wrong, but it is magnificent to fly.

Thanks jaba for the F/E's lament.

Ref the 2nd A380 video.
Allowing for 'lowish' landing weight of 340 tonnes Vref+5 = 134 knots (226ft/sec.)
4 -5 seconds for spoiler deployment.
Autobrake deceleration rates of 'LO' @ 4knots/sec or 'MED' @ 5knots/sec. Therefore average speed in that 4 second period is 125 knots (211ft/sec) (any HW would decrease the G/S)
The video shows the spoilers extended before the aircraft reaches the 1000ft touchdown zone marking.
You do the maths.

The closure rate of the wing shadow and the touchdown noise shows how the fin camera view is live.
