I skimmed through the video and did not pay attention to what they were talking about at all. The thing feels strange to me is that there was almost nobody else appeared in the video. Nobody was doing anything in the garden or just walking in the fields to enjoy the nature. The images taken from the sky also showed no sign of human activity. Again, I just skimmed through the video and I may have missed them.
It's a very common pattern when videotaping communities. Not everyone is happy to have a camera around, and there's usually agreements that the camera will stay in a certain corner and that only people who consent to be filmed will be on tape.
I don't know what time of day it was filmed. Maybe most people were working? There definitely were people around, at various points in the video.
If I look outside my home at any random time of the day, you typically don't see many people either. Perhaps a few children if its the right time of day and weather, but on most days there really aren't that many people around. The video had more people.
