It’s a clip taken from a film - Shadow On The Earth. Pretty sure the full film is on YouTube.
Set in a working class community in Scotland at the end of the 1950s it is a beautiful examination of idiotic adult divisions, social, religious, political and sexual, as seen through the eyes of Billy, an incredulous but obviously intelligent small boy. Billy and his somewhat less sensitive chums seem to pick up the multi-faceted bigotry, anger and paranoia of the surrounding grown-ups and distill this cocktail into their fear of a local shy and light-averse albino man, who they gradually convince themselves, is an alien from outer space.
