Public-domain archive films (Prelinger) and how to use them
Updated · 3 min read
Short answer
The Internet Archive holds hundreds of thousands of films marked public domain or Creative Commons, including the Prelinger Archives: thousands of 20th-century industrial, educational and advertising films whose public-domain status is stated by the collection itself. Most other uploads carry a licence chosen by the uploader, which nobody checks, so verify them before relying on them. Either way, the people and brands in old footage never signed releases: use it for documentary and editorial work, and be careful in ads.
Why so much old film is public domain
In the United States, works published in 1930 or earlier are now in the public domain. Many later films joined them because, under the law before 1978, copyright had to be claimed with a notice and renewed after 28 years; films published without a notice, or never renewed, lost their protection. Industrial, educational and sponsored films were often made for a single client and never renewed, which is why so many of them are free to use today. Works made by the US government, including many wartime and public-information films, were never copyrighted at all.
The Prelinger Archives
The Prelinger Archives are a collection of “ephemeral” films (industrial, educational, advertising and amateur films) assembled by the archivist Rick Prelinger. Around ten thousand of them are on the Internet Archive, covering roughly 1903 to the 1980s: assembly lines and kitchens, cars and highways, schools and civil defence, cities and suburbs. Because the collection itself states that these films are in the public domain, Video Assets Server treats their licence as stated by the source.
Everything else on the Internet Archive
Anyone can upload a film to the Internet Archive and pick its licence, and the Archive doesn’t verify it. Most uploads are honest, but some modern films and TV recordings carry a public-domain mark they shouldn’t. Video Assets Server only searches items whose licence is CC0, public domain or CC BY(-SA), leaves out TV captures, trailers and fan uploads, and caps uploader-chosen licences at Unclear: check the terms. Before you rely on one, check the item’s description for the original producer and year, and whether the film plausibly entered the public domain.
People and brands in old film
Copyright is not the only right in a film. The people in a 1950s newsreel or home movie never signed a model release, and the brands on its shop fronts are still trademarks. That is why archive footage carries the editorial flag: perfect for documentaries, essays and history channels, risky for an ad that uses a stranger’s face to sell something.
Working with archive footage in a modern edit
- Expect standard-definition transfers, 4:3 frames, film grain, flicker and black-and-white. Pillarbox rather than stretch.
- Films start with titles and countdown leaders: skip in, or let the sequence builder set the in-point.
- Frame rates vary (18, 24, 25 or 29.97 fps transfers); conform them to your timeline.
- Download the MP4 derivative for editing; the original files can be large or in older formats.
Questions
- Do I need to credit Prelinger films?
- Public-domain films need no credit by law. Crediting the Prelinger Archives and the Internet Archive is good practice and helps others find the material.
- Why do archive clips start with title cards and countdowns?
- They are whole films, not stock clips. Skip into the film to find the shot you need; the sequence builder starts long archive films part-way in for this reason.
- What resolution are archive films?
- Usually standard definition, often 480p or smaller, in 4:3. Pillarbox them in a 16:9 edit, or crop if the framing allows, and don't expect 4K.
- Can I upload a public-domain film to YouTube?
- You may, but automated systems sometimes match public-domain footage that someone else has claimed. Keep the source page link so you can dispute a claim.
