yep, super 8 film. the perforations are on one side. my guess is the perforations show up because of the change of aspect ratio from super 8 to HD then encompasses all of the film that is otherwise cropped when viewing in another aspect ratio. the square is in the same place because the frames don't contain information at the empty spot
i remember fake film burns circa 2011 on HD footage lol what a painful time
In related bitching, it's annoying when skate videos splice b horror film clips every couple of tricks. like the skating already kind of sucks if its some local or shop vid, and u aren't alien workshop so chill lol
