Even if the copyrighted material you use in your YouTube videos falls under Fair Use, you can still get into a lot of copyright issues and difficulties. The only entity that can determine if your use of copyrighted material falls under “Fair Use” or not is a court of law. YouTube doesn’t make any judgement calls on fair use. They only give copyright holders the ability to find their material on YouTube through Content ID and determine what they want to do with the video that’s using their material. Here’s a few rules to help you avoid violating fair use and running into copyright problems on YouTube.
