These are scenes from Gyimes, a small rural village in Transylvania. What I know about Transylvania comes from old Bela Lagosi Dracula movies. In the video I didn't notice any fellows eating flies or turning into bats, but perhaps that just wasn't filmed.
The village is in a valley in the Carpathians. Some of my ancestors came from around that area, so maybe a distant cousin or two was in the video. It is a pleasant looking place, although rather too rustic looking for my taste.
