Transformative Works and Fair Use:
The doctrine of fair use need not be so mysterious or dependent on intuitive judgments. Fair use should be perceived not as a disorderly basket of exceptions to the rules of copyright, nor as a departure from the principles governing that body of law, but rather as a rational, integral part of copyright, whose observance is necessary to achieve the objectives of that law.
I believe the answer to the question of justification turns primarily on whether, and to what extent, the challenged use is transformative. The use must be productive and must employ the quoted matter in a different manner or for a different purpose from the original. A quotation of copyrighted material that merely repackages or republishes the original is unlikely to pass the test; in Justice Story's words, it would merely "supersede the objects" of the original. If, on the other hand, the secondary use adds value to the original—if the quoted matter is used as raw material, transformed in the creation of new information, new aesthetics, new insights and understandings—this is the very type of activity that the fair use doctrine intends to protect for the enrichment of society. Transformative uses may include criticizing the quoted work, exposing the character of the original author, proving a fact, or summarizing an idea argued in the original in order to defend or rebut it. They also may include parody, symbolism, aesthetic declarations, and innumerable other uses.
Under the first of the four §107 factors, “the purpose and character of the use, including whether such use is of a commercial nature…,” the enquiry focuses on whether the new work merely supersedes the objects of the original creation, or whether and to what extent it is “transformative,” altering the original with new expression, meaning, or message. The more transformative the new work, the less will be the significance of other factors, like commercialism, that may weigh against a finding of fair use.
You can make music videos using anything at all as raw material as long as you are not taking from other music videos. That's the law. If you get a copyright claim on your Transformative Work, dispute it and site the law.
