Greetings from Maplevision (2016)

In the post-apocalypse, a Canadian documentary crew sent by their Government traverses the remnants of the United States, looking for any sign of life. Meanwhile, their anthropological assignment has been turned into a meandering reality show by their host and director, trying to be contained by their disgruntled producer. Slowly but surely, they run into life, though in a condition they could have never expected. (This is a teaser short for a potential series)

Unfortunately the movie Greetings from Maplevision is not yet available on HBO Max.
