We cannot expressly authorize you to upload video or use Funimation's content. We can tell you, however, that we do not plan to take legal action against creators/distributors of anime-based media that qualifies as a fair use of the underlying animation. Nor do we tend to remove such media intentionally, provided that the video is clearly marked in a way that would identify it as a fair use [in the title] such as a satire, parody, review or critique. For more on fair use, please see this Wikipedia entry: http://en.wikipedia.org/wiki/Fair_use
Also, please bear in mind that video streaming services such as YouTube occasionally employ "video fingerprinting" technology to identify and remove videos containing ANY unauthorized footage, whether it's arguably a fair use or not.
Basically, while we cannot expressly authorize you to upload such media, we will not actively seek to remove any that you do decide to upload, provided that it is [and is readily identifiable as] a fair use of the media, such as a satire, parody, AMV, critique or review. If you believe your content was taken down in error, please file a counter-notification for alleged infringement at http://video.google.com/support/bin/request.py?contact_type=cyc and follow the instructions, or submit a ticket with a member of our Support Team at help.funimation.com/contactsupport.
