Fair use is part of copyright law, and our main copyright and trademark page explains how it fits with registration and enforcement. The rule itself is short. 17 U.S.C. 107 says the fair use of a copyrighted work "for purposes such as criticism, comment, news reporting, teaching ..., scholarship, or research, is not an infringement of copyright," and lists four factors a court must consider. Commentary is on that list, but that is a starting point, not an answer: the Copyright Office says courts decide fair use case by case, and that only a federal court can determine whether a particular use is fair.
How a Court Analyzes a Reaction Video, Step by Step
- Pin down the specific use. In Warhol, the Supreme Court analyzed the specific use alleged to infringe, a 2016 magazine license, not every use ever made of the work. For a channel, that means this video, as published.
- Factor one: purpose and character. Does the video comment on or criticize the clip, or does it serve the same purpose as the original? Commerciality is weighed here too.
- Factor two: the nature of the work. The Copyright Office says using a creative work, such as a movie or song, is less likely to support fair use than using a factual one, and using an unpublished work is less likely to be fair.
- Factor three: amount and substantiality. How much was shown, and whether it was the heart of the work, measured against what the commentary needed.
- Factor four: market effect. Could someone watch your video instead of the original, or instead of a licensed version of it?
- Weigh them together. The Copyright Office notes that courts may consider other factors too, and the outcome depends on a fact-specific inquiry.
| Factor | What tends to help | What tends to hurt |
|---|---|---|
| 1. Purpose and character | Commentary or criticism that targets the clip and explains why you are showing it | Showing the clip for the same entertainment value it already has, with reactions as filler |
| 2. Nature of the work | Factual or news material; published works | Scripted, fictional or highly creative work; unpublished material |
| 3. Amount and substantiality | Short clips tied to specific comments | Long runs of footage, the whole work, or its most important moment shown without comment |
| 4. Market effect | Viewers still need the original to get what it offers | Your video works as a substitute for the original or for a license the owner sells |
Is It Commentary, or Is It Re-Airing?
This is the question that decides most reaction cases. The Supreme Court in Warhol described the "central" question of the first factor, quoting Campbell v. Acuff-Rose Music, as whether the new work "merely 'supersede[s] the objects' of the original creation," or instead adds something new, with a further purpose or different character. It added that criticism of a work "ordinarily does not supersede the objects of, or supplant, the work," because it uses the work to serve a distinct end.
The Court also explained why commentary gets room to copy. A use may be justified because copying is reasonably necessary to achieve the new purpose: parody "needs to mimic an original to make its point," and other commentary or criticism that targets an original work may have compelling reason to "conjure up" the original by borrowing from it. A reaction video that targets the clip, by questioning, mocking or correcting it, has that justification. A video that uses the clip as the show, with the creator's face in a corner, has much less of one.
The Copyright Office's Fair Use Index summarizes one reaction video case. In Hosseinzadeh v. Klein (S.D.N.Y. 2017), a filmmaker's five-minute skit was shown in portions, about three minutes, inside a fourteen-minute reaction video. According to the summary, the court found the first factor weighed heavily for the reaction creators because their video was "quintessential criticism and comment," and it described the video as turning the skit into "fodder for caustic, moment-by-moment commentary and mockery." The Office's summary reports that fair use was found. One district court decision does not set a rule for every channel, but it shows what the analysis looks at.
YouTube's own guidance points the same way: adding your material to someone else's content may still not be fair use if it adds no new expression, meaning or message. Our page on fair use of clips and photos in documentaries applies these points to longer-form footage.
How Much of the Clip Can You Show?
There is no number. The Copyright Office says there are "no legal rules permitting the use of a specific number of words, a certain number of musical notes, or percentage of a work," and its Fair Use Index adds that there is no formula for a predetermined amount. Courts look at both quantity and quality: using a small piece can still weigh against fair use if it is the heart of the work, and some courts have found use of an entire work fair in particular circumstances.
For a reaction video, the measure is what the commentary needs. In the Hosseinzadeh summary, the third factor came out neutral: showing clips was "plainly necessary" and "reasonable to accomplish the transformative purpose of critical commentary," but "a great deal of plaintiff's work was copied." Warhol supports looking clip by clip. Using a critical book review as an example, the Court said each quoted passage likely serves a different purpose than it does in the book, but that a court must consider each use within the whole. The same reasoning applies to text quoted on screen; see our page on quoting other works in a book.
Does Your Video Replace the Original?
The fourth factor asks about "the effect of the use upon the potential market for or value of the copyrighted work" (107(4)). The Copyright Office describes it as asking whether the use harms the existing or future market for the original, for example by displacing sales, and whether it could cause substantial harm if it became widespread. In the Hosseinzadeh summary, this factor favored the reaction creators because their video did "not serve as a market substitute" for the skit.
Warhol ties this factor to the first. The Court said a secondary use that is more different in purpose and character is less likely to usurp demand for the original work or its derivatives. So a reaction video that a viewer could watch instead of the original, or instead of a clip license the owner sells, has a weak fourth factor, and a weak first factor too.
Does Monetizing Your Channel Defeat Fair Use?
No, not by itself. In Campbell, the Copyright Office's summary says, the Supreme Court held that the lower court erred in giving dispositive weight to the commercial nature of 2 Live Crew's parody and in presuming it unfair; the commercial or nonprofit purpose is only one element of purpose and character. Warhol repeated that the commercial nature of a use "is not dispositive," but "it is relevant," and must be weighed against the degree to which the use has a further purpose or different character.
Warhol's change is in how much new expression buys you. The Court said new expression, meaning or message "may be relevant" but is not, without more, dispositive of the first factor, and warned that otherwise "transformative use" would swallow the owner's right to prepare derivative works. Where the original and the copying use share the same or highly similar purposes and the use is commercial, the Court said the first factor is likely to weigh against fair use "absent some other justification for copying." For a monetized channel, that justification is the commentary itself. Calling a video "for entertainment purposes only" is unlikely to tip the scales, YouTube notes, and a nonprofit purpose helps but is not an automatic defense.
Fair Use in Court Versus Surviving a Platform Claim
These are different tests. YouTube says automated systems like Content ID cannot decide fair use, which is a case-by-case decision only courts can make, so a strong fair use video can still get a claim. You defend it through the dispute, appeal and counter-notice steps described on our page about Content ID claims and copyright strikes, and YouTube says you may sometimes need to carry the dispute all the way to a counter-notice.
A counter-notice is a sworn statement, and it gives the owner your contact details and your consent to a federal court (17 U.S.C. 512(g)(3)). In Hosseinzadeh, the summary says, the counter-notice was followed by an infringement suit and a claim under 512(f) for misrepresentation in it; the court dismissed the 512(f) claim because the use was fair and because the creators needed only a subjective good faith belief that it was. Our page on what happens after a counter-notice covers the owner's side of that clock. For your side, see our page on what to do about a false DMCA takedown.

How Do Creators Build a Stronger Record?
- Script the commentary first. Decide what you are saying about the work, then choose only the clips that the point requires.
- Interrupt the clip. Pausing to comment, rewinding to make a point, and cutting away keep the original from playing as its own show.
- Treat every use separately. Warhol's book-review example says each use is considered within the whole, so a thumbnail, an intro montage or background music needs its own justification.
- Watch the music inside the clip. A song playing in someone's video has its own owner, and YouTube says a claim can follow even a few seconds of a popular song.
- Keep your notes. An outline showing why each clip was used is the record you want if you ever have to defend the video.
- Know the fallback. When commentary is thin, a license is the cleaner route; our post on legal ways to use copyrighted works covers licensing, the public domain and Creative Commons.
What Changes the Answer
- Parody versus satire. Warhol, following Campbell, distinguishes parody, which targets an author or work, from satire, which ridicules society without necessarily targeting the work. As Warhol quotes Campbell, parody "has some claim to use the creation of its victim's" imagination, while satire "requires justification for the very act of borrowing."
- An unpublished work. The statute says unpublished status does not by itself bar fair use (107), but the Copyright Office says use of an unpublished work is less likely to be considered fair.
- A factual source. Commenting on a news item or a technical explainer helps the second factor more than commenting on a scripted skit.
- The whole work. Showing all of a short video with little interruption makes the third and fourth factors hard to win.
- A viewer outside the United States. Fair use is U.S. law; YouTube notes the EU requires uses to fit categories such as quotation, criticism, review, caricature, parody and pastiche.
A Worked Example
For example, suppose a Macon film critic runs a monetized channel and reviews a popular 10-minute short film. Her 18-minute video shows about 90 seconds of the film in a dozen short clips, each followed by her analysis of the editing, the acting and the twist ending. She does not show the ending itself; she describes it.
On the factors: her purpose is criticism that targets the film, which gives her a reason to conjure it up. The film is creative, which weighs the other way. Ninety seconds tied to specific comments, without the ending, is a modest and purposeful taking. And a viewer who wants the film still has to watch the film. The video is monetized, but under Campbell and Warhol that is one consideration, weighed against a clearly different purpose.
Now change the facts: a watch-along stream plays the entire film with occasional jokes. The purpose is close to the film's own, the whole work is shown, and the stream can substitute for the original. That version is much harder to defend.
Common Mistakes
- Relying on a disclaimer. YouTube says phrases like "no infringement intended" or "I do not own" do not create fair use.
- Believing in a safe number of seconds. The Copyright Office says no such rule exists.
- Reacting without commenting. Facial expressions alone may add little of the further purpose the first factor looks for.
- Showing the payoff. The ending, the punchline or the hook can be the heart of the work.
- Assuming a platform decision settles the law. A released claim does not make a video fair use, and a claim does not make it infringing.
- Filing a counter-notice on autopilot. It is sworn, and it opens the door to a lawsuit in your home federal court.
What to Do This Week
- Pick one recent video and list every clip, thumbnail and song you used from someone else.
- Next to each, write the comment it supports; cut any clip that has none.
- Check whether any clip shows the original's ending, punchline or most important moment.
- Ask whether a viewer could skip the original after watching your video.
- Save your outline and edit files for the videos you publish.
- If a video draws a claim, decide whether to dispute it based on this analysis, not on the claim alone.
Frequently Asked Questions
Does Giving Credit Make a Reaction Video Fair Use?
No. YouTube says giving credit will not by itself turn a non-transformative copy into fair use, and crediting the owner is not permission.
Is a Reaction to a Music Video Treated Differently?
The same four factors apply, but music videos are creative works, and the song inside can be the heart of the video. YouTube also says a claim can follow even short uses of popular songs, so a Content ID claim may follow.
Is a Nonprofit or Educational Video Automatically Fair Use?
No. The Copyright Office says courts are more likely to find nonprofit educational uses fair, but that does not mean every one is. They still have to work through all four factors.
Can You Get Permission Instead of Relying on Fair Use?
Yes, and in cases of doubt the Copyright Office recommends getting it. A written license removes the question, though some creators will set terms or say no.
Does YouTube Ever Back Creators on Fair Use?
In rare cases. YouTube describes an initiative in which it has asked some U.S. creators to join, indemnifying up to $1 million in legal costs if a removal leads to an infringement lawsuit, for videos kept available only in the United States.
Who Ultimately Decides Whether Your Video Is Fair Use?
A federal court. The Copyright Office says that only a federal court can determine whether a particular use is fair, and it cannot give individual fair use advice.
Zala IP Law advises creators, channels and media businesses on copyright and fair use, from reviewing a video before it goes up to answering claims, takedowns and demand letters, and Shreepal J. Zala practices federal intellectual property law nationally. If a reaction or commentary video is under a claim or a threat, request a consultation or call 404-313-1701, and have the video link and the original you used ready.
