Now that is a powerful zoom! Let’s assume the purpose of this video is to advertise the camera’s powerful zoom even though the video didn’t inform us what the camera used is.
In the video, we first see an apartment. The camera zooms into one of the windows and we see a chick wrapped in towel. She removes it and we see her underwear. But that’s not the focus of this video.
The camera further zooms into the sunglasses on top of books lying near the window. Upon further zoom, we see one side of the sunglasses reflecting another building.
The camera zooms some more and we see a man in one of the windows standing behind a camera. And yeah, that is most likely the man recording right from the start.
