Fair use and public domain.
In order to facilitate the progress of society, certain uses of another person or companies copyrighted works may be lawful (and not infringing). A “fair use” of copyright depends on a 4 part analysis that courts go through to consider whether or not the use of a copyrighted work is “fair” (and thus lawful) or not a fair use (which becomes an infringement of copyright). The four part test is simple, yet can be complex, and depends on the 4 factors set forth in section 107 of the federal copyright law in the United States. This section states:

In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include—

1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
2) the nature of the copyrighted work;
3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
4) the effect of the use upon the potential market for or value of the copyrighted work. The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. The Courts can grapple with these four factors, and copyright holders, I guess you could say, are not real happy with the concept that you can just use their work, transform it, or comment on or criticize their works on your youtube channel (which many content creators like to try to monetize for commercial purposes). Nevertheless, the law allows certain fair uses. If you are claiming such a right, using a disclaimer at the beginning or end of your videos might put the copyright holder on notice that you did not seek their permission (or need to seek their permission) to use their works because you consider your use to be a legally protected use, such as for comment or criticize, or discussing the news under the first amendment free speech clause of the US Constitution.
