Where is this in Germany (Austria)?

Hint: This is Deutschland über Alles, not Österreich über Alles.
Yes, the first view is a church, Die Wallfahrtskirche St. Coloman in Schwangau, and that is Neuschwanstein in the background, on the hill.
Next scene is Heidelberg
Rothenburg is easily recognizable at 1:22
At about 2 min, that the same church from the first scene?
Hohenschwangau at 2:17
Is 3:09 Stahleck in Bacharach (no another castle, not Stahleck. Burg Katz, I think)

Thanks everyone for the quick replies.
