Here's a forensic description of the video: The video shows a group of young people dressed in traditional Bulgarian folk costumes performing on a stage outdoors. They are standing in front of a building, with the Bulgarian flag and the European Union flag hanging above. A banner that reads "ЗАНАЯТ ФЕСТ" (likely a crafts festival) is displayed in front of the stage. Several people are watching the performance, and one woman is taking a picture with her phone. The overall setting appears to be a public square or plaza.
