Can You Post Part of Someone Else's Video on YouTube?

No. YouTube does not publish a five-, ten-, or 30-second rule that automatically permits using part of someone else's video. A short clip can still be protected, can still receive a Content ID claim, and can still raise a copyright dispute. The most reliable starting point is whether you have permission or a license for the exact footage and use.

A public video, search result, transcript, title, thumbnail, or social post is not permission to reuse the underlying footage, narration, music, script, or artwork. Record the source and rights basis before you download, edit, or publish material that you did not create.

This is general platform and copyright information, not legal advice. If your plan relies on a copyright exception, a dispute, or a high-value commercial use, get advice from a qualified lawyer in the relevant jurisdiction before publishing.

Permission or a license is the clearest rights basis. Confirm who owns the video and any embedded music, artwork, footage, or performances, then confirm that the agreement covers the edit, platform, territory, duration, and monetization you intend. Keep the written permission, license, invoice, or relevant terms with the project record.

Public-domain material and Creative Commons material can have different conditions. YouTube's copyright guidance explains that public-domain status and copyright exceptions are separate concepts, and that terms can differ by jurisdiction. Check the specific source and license rather than assuming that a label, attribution request, or search filter clears every use.

Use the YouTube Source Review Template to record the owner, source URL, permission or license basis, attribution requirement, and remaining questions. The worksheet documents a review; it does not grant rights or provide legal clearance.

In the United States, fair use can allow some unlicensed uses in particular circumstances, including examples such as commentary, criticism, research, teaching, or news reporting. But it is fact-specific. YouTube says courts decide fair-use cases, and the U.S. Copyright Office explains that the law calls for weighing four factors rather than applying a fixed clip length or formula.

The four U.S. factors include the purpose and character of the new use, the nature of the copyrighted work, the amount and substantiality used, and the effect on the potential market. A smaller amount can still be important if it takes the heart of the work, and adding material of your own does not automatically make the use fair.

Rules outside the United States can differ, including fair-dealing and other local exceptions. Treat a legal exception as a question for qualified local advice, not as a permission substitute generated by a tool or inferred from another creator's workflow.

Giving credit can be required by a license or be good editorial practice, but it does not by itself give you permission. YouTube's current copyright-myth guidance says that phrases such as 'no infringement intended' and statements that you do not own the material do not automatically protect an upload from a copyright claim.

Commentary, criticism, or a reaction can add original value, but it is not an automatic defense. The context, material used, rights basis, and applicable law still matter. Avoid treating a voiceover, crop, speed change, caption, or short excerpt as a universal way to clear someone else's work.

Keep attribution accurate when a license requires it, but make the rights decision before the credit line is written. Attribution is not a substitute for permission, a license, or jurisdiction-specific legal analysis.

YouTube explains that an upload containing copyrighted material without permission can receive a copyright claim, including when only a short amount is used. Content ID does not decide whether a use qualifies for fair use because that analysis is subjective and case-specific.

Do not treat a claim dispute or counter notification as a casual test. Review the claim details, the exact rights basis, and the consequences before responding. When you are uncertain, remove or replace the material and seek qualified advice rather than escalating an unsupported dispute.

If you have confirmed permission to reuse a source, YouTube Downloader & Editor can be the next production handoff. Confirmed permission is still required; finding, importing, or editing a source does not establish rights clearance.

YouTube's channel monetization policies separately review reused and inauthentic content. For monetization, YouTube expects original, authentic work and says it can remove monetization when a channel repurposes material without significant original commentary, substantive modification, or educational or entertainment value.

That review is separate from copyright. YouTube explicitly notes that content can avoid a reused-content problem while still being subject to copyright policies, and it also says a channel can have reused-content monetization issues even when the uploader has permission from the original creator.

Build the video around your own reporting, analysis, story, or instruction. Make the original contribution visible to a viewer and retain the evidence that supports your use of third-party material. Do not scale interchangeable clip compilations or lightly edited reposts as a monetization strategy.

Before export, separate four questions: do you have permission or a license, are you relying on a specific legal exception, could the clip trigger a platform claim, and does the finished video show a meaningful original contribution? One positive answer does not automatically answer the others.

Keep the original source, terms, rights owner, allowed use, attribution text, clip selection, editorial purpose, and reviewer in the project record. If any answer is unclear, pause the use of the clip and obtain the missing permission or advice.

For an edit plan after the rights basis is confirmed, use Satura's Free Video Editor to assemble the authorized footage and review the final timeline. The editor is not a copyright-clearance tool and does not determine whether a use is fair, licensed, monetizable, or publishable.
