Fair use and reposting X videos: a plain-language guide

We run a tool that saves videos from X, so we think about copyright more than most people. The same questions keep coming up: "Can I repost this clip if I give credit?" "Is it fair use if I add commentary?" "Is it legal to download a public video?" The honest answer to most of these is "it depends", but it depends on things you can understand and reason about.

This guide explains the ideas in plain language. It is not legal advice. We're not lawyers, laws differ between countries, and courts decide fair use case by case. If money, a client or your channel is at stake, talk to a lawyer where you live. What we can do is help you ask the right questions before you hit "post".

Start with the default: someone owns that video

Almost every video on X is protected by copyright the moment it's recorded. The person who shot it (or their employer, or a broadcaster who licensed it) owns it. Posting it publicly on X doesn't give up those rights. It only means people can watch it on X, under X's terms.

When you upload to X, you give X a licence to show your content on its service. That licence is between you and X. It doesn't give other users a right to download your video and upload it somewhere else.

So reposting someone else's video is, by default, something that needs permission, unless an exception applies. Fair use is the best-known exception.

What fair use is (and where it applies)

"Fair use" is a doctrine of United States law (Section 107 of the US Copyright Act). It lets people use copyrighted material without permission in some circumstances, typically for criticism, comment, news reporting, teaching, scholarship and research. It isn't a list of allowed activities. It's a balancing test, and courts weigh four factors.

Factor 1: The purpose and character of your use

Are you doing something new with the clip, such as commenting on it, criticising it, analysing it or reporting on it? Or are you just showing it again for the same reason the original was made? Courts call the first kind "transformative", and it weighs strongly toward fair use. Commercial use (ads, sponsored posts, monetised compilations) weighs against it, though it doesn't automatically rule it out.

• Stronger case: a 10-second excerpt in a video essay that explains why the clip went viral and what it gets wrong.
• Weaker case: a "best clips of the week" compilation that strings together other people's videos with a music bed and a logo.

Factor 2: The nature of the original work

Using factual material (a news clip, a recording of a public event) is more likely to be fair than using highly creative work (a short film, an animation, a music video). Whether the original was published also matters; unpublished work gets more protection.

Factor 3: How much you used

Using only what you need for your point helps. Taking the entire clip is harder to justify, though not impossible: commenting on a 6-second video may require showing all 6 seconds. Taking the "heart" of a work, its most valuable moment, can weigh against you even if the excerpt is short.

Factor 4: The effect on the market for the original

Does your use replace the original? If people can watch your repost instead of the creator's post, or instead of licensing the clip, that harms the market and weighs heavily against fair use. Viral-video creators often license their clips to news outlets and brands. Reposting that same clip in full competes directly with that.

Myths we hear all the time

"I gave credit, so it's fine." Credit is polite and often required by licences, but it isn't permission. "No copyright infringement intended" disclaimers don't change anything either.

"It was public, so anyone can use it." Public means viewable, not free to reuse.

"I only used less than 30 seconds." There's no safe number of seconds in fair use law. Short uses are often fair; they aren't automatically fair.

"I'm not making money from it." Non-commercial use helps under Factor 1, but non-commercial copying of an entire work can still infringe.

"Everyone else reposts it." Other people's risk doesn't reduce yours, and platforms' automated systems do catch reposts.

Outside the US: different rules

Most countries don't have "fair use". They have specific exceptions, often called "fair dealing" (the UK, Canada, Australia and others) or lists of permitted uses such as quotation, news reporting, parody, teaching and research (common in the EU and many civil-law countries, including Morocco). These exceptions tend to be narrower than US fair use and depend on the exact purpose: quotation for criticism or review, for example, usually requires that the work was already lawfully published, that the source and author are named, and that you only use what's justified.

Because X is used everywhere, a repost can be seen by people in many countries. Platforms usually handle disputes through their own copyright processes (for example DMCA-style takedowns), regardless of where you live.

How this plays out on X and other platforms

In practice, most reposting disputes never reach a court. They're handled by platform systems:

• The owner files a copyright report, and the platform removes the post or disables the media. On X, you'll sometimes see a notice that media was disabled in response to a report by the copyright owner.
• Repeated reports can lead to account restrictions or suspension.
• On video platforms with content-matching systems, a reused clip can be claimed (ad revenue goes to the owner) or blocked.
• You can usually submit a counter-notice if you believe your use was fair. Do it honestly; false counter-notices can carry legal consequences.

Safer ways to share a clip

When you want people to see a great video someone else posted, these options carry far less risk than re-uploading:

1. Repost or quote it on X. The native repost and quote features keep the creator's post, credit and view count intact. That's what they're for.
2. Embed it. On a website or blog, use X's official embed (from the post's Share menu or the post's … menu, depending on the version). The video stays hosted by X under the creator's control, and if they delete it, it disappears from your page too, which is how it should be.
3. Link to it. A link with a short description of what's interesting is always fine.
4. Ask for permission. It costs nothing to try. Our guide on asking a creator for permission has message templates you can copy.
5. License it. Many viral clips are managed by licensing agencies. If you're a brand or a publisher, this is the professional route.

A quick self-check before you repost

Ask yourself:

• Am I adding something meaningful such as commentary, analysis or reporting, or just re-showing it?
• Am I using only the part I need?
• Could my post replace the original for viewers?
• Is this commercial: a client, an ad, a monetised channel?
• Have I credited the creator clearly and linked to the original?
• Would I be comfortable explaining this use to the creator directly?

If several answers point the wrong way, use the native repost, embed it, or ask.

Where downloading fits

Downloading and reposting are separate questions. Saving a clip for personal use (watching offline, keeping a reference, preparing commentary you'll publish with a short excerpt) is very different from re-uploading the full video to your own account. Our responsible use page sets out what we think is fine and what isn't. In short: download what you own, what you have permission to use, or what you'll use within a genuine exception such as short, attributed excerpts for commentary or news.

Troubleshooting common situations

My repost was removed for copyright. What now? Read the notice carefully. If you didn't have permission and don't have a strong fair-use argument, accept it, remove similar posts, and ask the creator directly next time. If you believe it was fair use (for example, a short excerpt in genuine criticism), you can file a counter-notice through the platform's process.

Someone reposted MY video without asking. Start with a friendly message; many reposters will credit you or take it down. If not, use X's copyright report form. Our DMCA page explains how to ask us to block a specific post from our tool.

The creator is impossible to contact. That doesn't make the clip free to use. Use the native repost or embed, or find a licensed alternative.

I'm a teacher and want to show a clip in class. In-class display for teaching is one of the uses many countries' laws allow, but rules differ for showing a clip in person versus uploading it to a public course page. Check your institution's guidance.
