Public domain, footage that holds no copyright and is free to use by the public, is music to the ears of a documentary filmmaker. But determining what footage is in the public domain, and how to get it for free, can be quite a chore. 

Here are The 3 Best Completely Free Stock Footage Sites

Footage generally falls into public domain because it was created by an entity not subject to copyright (like most of the US Government), or the copyright has expired. You can check the 2015 US Public Domain and Copyright Term for current laws governing when copyright expires. If you’re new to public domain film.

However, once you find footage that is in public domain, it can still be hard to get a copy of it for free. (And the same can be said for footage that you plan to us under "Fair Use" but that's another story.) There are usually two reasons you have to pay for something: your public domain footage is sitting in a vault somewhere and you need to pay someone to find it, or transfer it to the format you need, then ship it to you. Or a third party already has a useable copy of the footage and is selling it to you for that convenience. 

As we’ve discussed, the search for archives is often the scriptwriting process on a documentary, and can be crucial to your film's success.

If you've stumbled onto footage on your subject that has yet to have been digitized, by all means pay to get your hands on it. But since no one wants to pay for something they don’t have to, especially documentary filmmakers on a shoestring budget, here are some great free sources:

Prelinger Archives housed at

Prelinger Archives was founded in 1983 by Rick Prelinger in New York City. Over the next twenty years, it grew into a collection of over 60,000 "ephemeral" (advertising, educational, industrial, and amateur) films...Prelinger Archives remains in existence, holding approximately 11,000 digitized and videotape titles (all originally derived from film) and a large collection of home movies, amateur and industrial films acquired since 2002. Its primary collection emphasis has turned toward home movies and amateur films, with approximately 12,000 items held as of Spring 2015. Its goal remains to collect, preserve, and facilitate access to films of historic significance that haven't been collected elsewhere. 

Strings attached: If you need written permission to clear your footage, you might need to pay Getty for it. From Prelinger

“The Internet Archive does not provide written permission to use any material, and the user therefore assumes all risk when repurposing Prelinger footage. By way of contrast, when you license Prelinger clips from Getty Images, Getty Images will indemnify you against claims for copyright infringement relating to copyright in the footage clip.”

The Internet Archive Moving Image Archive

Strings attached: Anyone can upload to the Internet Archive, so there is a lot to sort through with all kinds of copyright status. Even when listed as public domain by the uploader, be discerning.
