How does it work, technically? Is there an API to pull videos with a certain title format within a certain range, and then are the sections of video randomly chosen?
Edit: Found this https://github.com/wonga00/astronaut - answers some questions:
> The server currently pulls in videos daily from youtube. Search criteria is [TAG]XXXX with upload time this week, where TAG is a raw video prefix such as 'dsc' or 'img'. This search turns out to be a good approximation for the data set of home videos created in the last week.
