It appears the aircraft flared a little too early, which caused it to catch some ground effect.

The flare is the maneuver that a pilot does during landing in order to slow the aircraft and set it gently down onto the runway. By pulling the nose up it increases the drag of the aircraft, which slows it down. As the wing's angle of attack increases it will eventually stall and loose lift. So to land the aircraft the pilot descends until the aircraft is only a short distance above the runway, the flies horizontally above it while pulling nose higher and higher. The aircraft slows, stalls, and settles onto the runway, at which point the pilot deploys lift-killing devices on the wings and engages reverse thrust to assist in braking.
Ground effect occurs when the aircraft is close to the ground. When the air passing underneath the wing is compressed between the wing and the ground it gives more lift to the aircraft, which can delay the stall and cause the aircraft to travel a lot further down the runway before it actually lands. That's what appears to have happened in the video.

Also how long is the runway at VYR? Is it a bit too short for A380?

Well if it was too short then they wouldn't be trying to land there. The north runway is 9940 feet long, so I have to assume that it's long enough for the A380 at whatever landing weight it happened to be. But there's probably not a whole lot of extra distance available, so if those wheels aren't on the ground where they're supposed to be then a go-around is of course the smart thing to do.
