Is 30 seconds of a video fair use?

There is no official answer for 30 seconds or any other length. The Copyright Office says fair use is decided case by case on four factors, and that no set amount is guaranteed to be allowed without permission.

How long does a clip have to be to get copyrighted?

There is no minimum length in the pages we read. US copyright exists from the moment an original work is fixed, and YouTube says even a few seconds used without permission may lead to a claim.

How long of a movie clip is fair use?

No official page gives a safe length. Movies count as creative works, which the Copyright Office says are less likely to support fair use, and using the heart of a work can weigh against you even if it is short.

Who decides whether my clip is fair use?

Ultimately only a federal court can. Content ID and other automated systems cannot decide it, and the Copyright Office cannot give legal advice to individuals about whether a particular use is fair.

Does giving credit to the podcast make a clip fair use?

No. YouTube says crediting the owner will not by itself turn a copy into fair use, and phrases like "all rights go to the author" do not mean fair use or permission.

Are the fair use rules the same outside the United States?

No. Fair use is a US doctrine. YouTube says the EU uses specific categories such as quotation, criticism, review and parody, and some countries use fair dealing, so check the rules where you and your audience are.

How long can a clip be without copyright? There is no safe number

By Rakshit · Updated October 11, 2026

No length is safe. The US Copyright Office says fair use has no formula that guarantees a set percentage or number of words, lines or pages, and YouTube says even a few seconds used without permission can lead to a claim. Fair use is weighed on four factors, case by case, and only a federal court can decide it.

Why 10 seconds, 30 seconds or 15% is a myth

The rule people half-remember is that a clip under some number of seconds is fine. No official page we read says that. The Copyright Office's fair use page says fair use is judged case by case and that there is no formula to ensure that a predetermined percentage, or a specific number of words, lines, pages or copies, may be used without permission. Its FAQ repeats the point for quotes: no legal rule permits a specific number of words, notes or percentage. The pages we read from the Office do not mention seconds or minutes at all, because the idea is not a legal test.

YouTube takes the same line from the platform side. Its copyright myths page says any amount of copyright-protected content used without permission, even a few seconds, may lead to copyright issues, and that only a court can decide whether a use is a copyright exception. The other half of the question, how long a clip has to be to get copyrighted, has the same answer in reverse: nothing in those pages sets a minimum. Copyright in the US exists automatically from the moment an original work is fixed, and a recorded episode is fixed.

The four factors, with podcast questions

Section 107 of the Copyright Act lists four factors a court weighs. The list is not closed, and no single factor decides the outcome. In plain English, with the kind of question each raises for a clipper:

Paraphrased from the US Copyright Office Fair Use Index and Section 107, read 2026-10-11.
Factor	What the Copyright Office says	A podcast question it raises
1. Purpose and character	Noncommercial and educational uses are more likely to be fair, but not every commercial use is unfair. Transformative uses, which add something new and do not substitute for the original, are more likely to be fair.	Does your clip add commentary or criticism, or does it just replay the best 40 seconds for views?
2. Nature of the work	A creative work such as a novel, movie or song is less likely to support fair use than a factual work. Unpublished work is less likely to be considered fair.	Is the source a scripted or performed show, or a factual discussion? The Office names a novel, movie or song as creative works and a technical article or news item as factual.
3. Amount used	Courts look at quantity and quality. A small amount is more likely fair, but even a small piece was held not fair where it was the "heart" of the work.	Is your clip the one moment people would listen to the episode for, such as the reveal in an interview?
4. Market effect	Courts ask whether the use hurts the current or future market for the original, for example by displacing sales.	Could someone watch your clip and skip the episode? Or does it point people to the full show?

Length bears on factor 3, and there it comes with quality attached. A 12-second clip that gives away the punchline can weigh worse than a longer, plainer one. That is why seconds cannot be the test.

Why short clips still get claimed

YouTube says automated systems like Content ID cannot decide fair use. A Content ID match is generated automatically when an upload matches a database of files submitted by owners, and a claim keeps you from monetizing the video even if you only use a few seconds. It can also block the video or let the owner run ads on it. YouTube's three-minute Shorts page says an active claim on a Short longer than one minute blocks the video worldwide, though another YouTube article words this differently.

A claim is not a strike. A strike comes from a valid copyright removal request, and three strikes in 90 days put a channel at risk of termination.
If you believe a use is fair, you can dispute a claim. YouTube lists credit to the owner, owning a copy of the video, and choosing not to monetize as reasons that do not count. Disputing without a valid reason can lead the owner to request removal, which can mean a strike.
TikTok's policy says not all unauthorized uses are infringement and names fair use in the US, but it also bans repeat infringers and may remove content once it is reported.

Things that do not make a clip safe

Giving credit. YouTube says crediting the owner will not by itself turn a non-transformative copy into fair use.
A disclaimer. There are no magic words. "No infringement intended" or "I do not own this" does not protect you.
Buying or recording it. Owning a DVD or recording something off the air does not give you the right to upload it.
Other channels doing it. Similar content existing on YouTube does not mean you have the rights.
Changing it a lot. The Copyright Office says you cannot claim copyright in another person's work, however much you change it, without the owner's consent. Adding something may help a fair use argument, but YouTube warns that if you add no new expression, meaning or message it probably is not fair use.

Rules also differ by country. YouTube says in the EU the use must fit specific categories such as quotation, criticism, review, caricature, parody and pastiche, and some countries use fair dealing instead of fair use.

What to do instead of counting seconds

Use your own recordings, or ask. The Copyright Office's general rule is to seek permission from the owner, and it recommends getting permission in cases of doubt. See our guide on posting podcast clips on TikTok and YouTube for what to put in a request.
Keep the permission in writing, covering the episode, the guest and any music in it.
If you rely on fair use, treat it as a defence you may have to argue later. The Office says that only a federal court can determine whether a use is fair, and that a third party need not accept your own assertion.
If you get a notice, know the process. A takedown notice does not mean you are being sued. You can leave the material down or send a counter-notice, and after a compliant counter-notice a provider must restore it after ten to fourteen business days unless the sender says it has filed a court action.

The stakes are real, not a technicality. The Office's FAQ says infringers may face statutory damages of up to $30,000 for each work infringed and up to $150,000 if willful infringement is proven. If you are worried about a particular use, the Office advises consulting an attorney.

Where KeyMo fits

KeyMo's clip length setting is an editing choice, not a legal one. Auto makes clips of 15 to 90 seconds, Short 20 to 40, Medium 40 to 60 and Long 60 to 90, and none of those lengths changes who owns the audio. Before it imports a YouTube link, KeyMo asks you to confirm that you own the video or have permission, and that is the step that matters. KeyMo has no free plan; Starter is $12 a month for 300 source minutes. If the episode is yours, the podcast clip generator turns it into captioned 9:16 clips.
