This seems to be the original video: https://vimeo.com/485177664 coming from:
https://handmadecities.com/media/ where at the bottom it notes:
each video is downloadable and released under CC BY-NC-ND 4.0.
Lucy does correctly mention the license in the description, although I am not sure if there should be some other attribution or not, the website does not mention who the copyright holder is. But I think it's okay, Lucy is not stealing videos.
