A plain-English guide to Creative Commons licenses for video
9 min read
Creative Commons licences are how a huge amount of genuinely reusable video gets shared. They are also widely misunderstood — most often by people who assume "Creative Commons" is a single thing meaning "free to use". It is not. It is a family of six licences with materially different conditions, and the differences decide whether what you are planning is permitted.
What a CC licence is
A Creative Commons licence is a standing grant of permission from the copyright holder. The work remains under copyright — the creator keeps it — but they have publicly stated in advance what others may do without asking. That is the whole mechanism: instead of contacting the creator and negotiating, you read the licence and comply with it.
Two consequences follow. First, only the copyright holder can apply one, so someone re-uploading a video they did not make cannot validly mark it CC. Second, the permission is conditional: fail the conditions and you are simply infringing copyright, exactly as if no licence existed.
The four building blocks
Every licence is assembled from up to four conditions.
BY (Attribution) appears in all six current licences. You must credit the creator. In practice that means naming the author, linking to the original where practical, naming the licence, and noting any changes you made.
SA (ShareAlike) means anything you build from the work must carry the same licence. This is the "viral" condition — it propagates.
NC (NonCommercial) forbids use primarily intended for commercial advantage. This is the vaguest term in the system and the most frequently misjudged.
ND (NoDerivatives) means you may share the work but not publish a modified version of it.
The six licences
CC BY — use it for anything, including commercially, modify it freely, just give credit. The most permissive.
CC BY-SA — as above, but anything derived must also be BY-SA. This is the licence Wikipedia uses.
CC BY-ND — you may redistribute it, commercially or not, but only unchanged and in whole.
CC BY-NC — modify and share freely, but not for commercial purposes.
CC BY-NC-SA — non-commercial, and derivatives must carry the same licence.
CC BY-NC-ND — the most restrictive: share it unchanged, non-commercially, with credit. Nothing else.
Separately, CC0 is not really a licence but a waiver: the creator has relinquished their rights as far as the law allows, placing the work effectively in the public domain. No attribution is required — though crediting anyway is good manners.
The mistakes people actually make
Assuming NonCommercial means "not selling it". It is broader than that. A video on a monetised channel, in a paid course, or on a company's marketing page is commercial use even if nobody paid for that specific clip. If the context is a revenue-generating activity, assume NC excludes you.
Treating attribution as optional if it's awkward. It is a condition, not a courtesy. Attribution that is buried, or omitted because the format made it inconvenient, does not satisfy the licence — and the licence is the only thing standing between you and an infringement claim.
Missing that ShareAlike is contagious. Using a BY-SA clip inside a larger video generally means the whole resulting work must be released under BY-SA. For a personal project that may be fine; for commercial work it frequently is not, and people discover this late.
Believing edits escape NoDerivatives. Trimming, adding music, overlaying text and re-cutting are all derivative works. ND permits sharing the original as it stands, and little else.
Trusting a label without checking who applied it. Anyone can type "Creative Commons" into a description. Only the actual rights holder can grant the licence. Re-uploads marked CC are extremely common and legally worthless.
How to attribute properly
The usual shorthand is TASL: Title, Author, Source, Licence. Something like: "Coastal Timelapse" by A. Rivera, source: [link], licensed under CC BY 4.0. Colour graded and trimmed from the original.
Note the last part. If you modified the work, saying so is part of the requirement under 4.0 licences — partly to be honest with viewers, partly so the original creator is not associated with your changes.
Licence versions and irrevocability
Licences carry version numbers, 4.0 being current. Earlier versions differ in detail — 4.0 handles database rights and attribution more clearly, and gives a 30-day window to correct a violation before the licence terminates. Always cite the version you relied on.
One important protection: CC licences are irrevocable. If a creator later changes their mind and removes the CC marking, copies distributed under the original licence remain licensed. What you may not do is rely on a licence that was never validly granted in the first place. If you plan to use something CC-licensed in work that matters, record what the licence said and when you retrieved it — that record is what protects you later.
