The interesting thing in this video is the apparent lack of knowledge about how to do a crosswind landing at the flare. The crab is good until just before touchdown. Then it should be converted to a slip. See if you notice upwind wing down and rudder to the downwind side. Mostly, no.
On the takeoffs, rudder should be on the downwind side and upwind aileron should be up. See if you notice that. Mostly no.
