Looks to me like a nervous stude with the control column in a rigid death-grip cocking up a moderate crosswind landing. There is a noticeable snatch upwards or check of the nose while the wheels are still visible followed by it being lowered again (incorrectly, imho) which leads into the excursion that looks rather wheel-barrow-ish to me. There seems to be much flailing of the rudder and late deployment of the ground spoilers as there is no weight on the main gear for a while after 'landing' so the wings retain unwanted lift longer than usual. At that point, nosewheel on, crossed controls to decrab but stil 'flying' the PF prematurely releases pressure on the (right) rudder or overdoes the wing down and an excursion and wing-drop to the left immediately occurs. The use of rudder looks panicky rather than positive and measured.
Easily done.
