Looking at the on-board clip, I have been on worse landing at NCE. It was sea-sky-sea-sky out the window. Pilot claimed it was wind off the Alps. I've never heard so many people vomiting. However at no time did I feel at risk.
From outside it looks worse!

The roll rate appeared to be proportional to the visible control surface deflection. In other words, the roll appeared to be commanded, rather than inflicted upon the aircraft from say rotor, as has been suggested, which would be countered by the opposite movement of the control surface from that seen. It would be interesting to learn whether it was intentionally or unintentionally commanded.
Either case would require some explaining, now that this is published for everyone to see, with both inside and outside views confirming the roll commands and the associated quite obvious effects on the aircraft. It seems highly unlikely that it would be commanded by the autopilot.

Rotors was my initial suggestion based on altitude wind ( not surface wind), temp/lapse rate and pressure. Now I’m not so convinced. The latest video is somewhat alarming but the problem rectified itself as altitude gained and when abeam the rock, so it could still be a factor. Now I’m thinking some form of FCC error. Worrying .

That guy’s uneasy “hehehe” laughter will haunt me tonight.. Pretty sure most people thought it was game over after the first two rolls.

What struck me (from the footage [interior, stbd]) was how quickly the oscillation stopped. Almost as if the guilty logic was taken out of the pipeline and the aircraft returned to doing what it was designed to do with immediate effect.
I'm quite convinced that this had nothing to do with rotor or pilot input. I could be wrong.

Just to add to my post#13 this does show the limited airspace allowed by Spain to aircraft using GIB airport Air restrictions imposed by Spain

Could not the explanation be simply that one of the pilots decided to wag the wings from side to side for the hell of it, possibly thinking that the turbulence from the rock would cover their tracks? It must get rather boring flying to the rules - even pilots want to have a bit of fun once in a while..

Rotor
Looks to be rotor induced, look at the ragged, torn little clouds in the opening shot. The rotor doesn't have to come off the rock, plenty of ridges out there. The go around was a hot mess, was it on auto or PIO? Anyway, I'm sure some PAX became reacquainted with Jesus.

After looking at the longer passenger footage, it looks to me like it’s the old ‘roll inconsistency in config full’ with “wind peturbation” (or whatever similar quaint phrase Airbus used to use) rearing its ugly head again.
I say this because the flaps appear set in the FULL position at the start of the footage. Immediately the roll oscillations stop, you can see that the flaps are in a lower config. Shortly after, the chime of gear retraction can be heard.
So I’m guessing that they got a windshear (coincident with the first jolt in the video), then commenced the windshear escape, all the while maintaining the current config.
Once out of the shear and on the “go around, flaps” actions, the FCCs resumed their normal behavior.
Just my two cents worth.
