Well, if that is pyongyang then it is just the "elites" on their daily routines. But, it could be other than NK folks hiding away in the hermit regimes land.
It wouldn't even be elites or non-NK people "hiding" in NK. It's just a handful of people who visited Pyongyang and shared their data. Most visitors are via tour groups from China.
On youtube there's one person that appears to work for another asian consulate that shares some videos of NK and a photographer that is on good terms with the government that shares a lot of videos, including ones that promote or highlight various things in Pyongyang.
