There’s no information to go with this video on YouTube, but apparently it is a camera strapped to a model airplane. Pretty cool!
Update: I got an email from Nicholas Lin who created this video. He provided a link to a video shot with a better camera and some info on his process:
The plane is flown birds eye view. I have a camera on the plane that records as well as sends live video to a set of video goggles that I wear to fly. It’s amazing to be able to see Providence from that perspective. I live on the East Side of Providence and love the city!
