Code of Best Practices in Fair Use for Online Video
ONE: COMMENTING ON OR CRITIQUING OF COPYRIGHTED MATERIAL
DESCRIPTION: Video makers often take as their raw material an example of popular culture, which they comment on in some way. They may add unlikely subtitles. They may create a fan tribute (positive commentary) or ridicule a cultural object (negative commentary). They may comment or criticize indirectly (by way of parody, for example), as well as directly. They may solicit critique by others, who provide the commentary or add to it.
PRINCIPLE: Video makers have the right to use as much of the original work as they need to in order to put it under some kind of scrutiny. Comment and critique are at the very core of the fair use doctrine as a safeguard for freedom of expression. So long as the maker analyzes, comments on, or responds to the work itself, the means may vary. Commentary may be explicit (as might be achieved, for example, by the addition of narration) or implicit (accomplished by means of recasting or recontextualizing the original). In the case of negative commentary, the fact that the critique itself may do economic damage to the market for the quoted work (as a negative review or a scathing piece of ridicule might) is irrelevant.
