Well, I'd say the vestibule shot of a Mk3 SLEP is very out of place in Krakow.
I wouldn't be surprised to find that someone spliced this whole video together from other videos (perhaps not even theirs).
There are several sections spliced in which don't fit, at least a couple being from Czechia (ČD and Regiojet trains, which I doubt get to that part of Poland).
I don't recognise the green fields (and what looks like a lineside pipeline) between Berlin Friedrichstrasse and Hbf!
And you cross the "Order" river rather than the Oder/Odra.
