I am trying to find video/tv/film footage relating to city travel. The
kind of footage would be about cities around the world, be it city
travel guides, footge of attractions, museums, tours, accommodation, airport
and travel info. Ideally it would be professional footage or if not
some amateur content.

It would need to have no copyright restrictions so I can
publish/stream the footage on my travel websites.

I have heard that some TV Broadcasting companies have released some of
their content/archives with no copyright restritions. Plus any other sources.

Thanks
