Vox is particularly strong when it comes to creating videos that don’t necessarily rely on footage they have shot themselves. Rather, they look to create a mini-documentary based on archival and found footage. There are many websites and resources that offer footage for copyright free. Moreover, I believe copyright material (film, television, etc.) is allowed to be used as long as you use less than 30 seconds. Regardless, this is a great example of a longer form video to accompany a longer story.
