Videos of just walking the streets of various cities. It's nice to have pictures and descriptions of the usual go-to places, but show me what the place is actually like.
How long do you think the video should be? and from what vantage point? maybe filmed by a drone? or on a bike?
Also do you want videos from the insides as well?
I am currently watching a series on Netflix called "The Layover" by Anthony Bourdain. It's a great travel show, but I wish it would show more of the street life of the places he visits.
