Fair use on YouTube
Fair use is a legal doctrine that says you can reuse copyright-protected material under certain circumstances without getting permission from the copyright owner.

Fair use guidelines
Different countries have different rules about when it’s OK to use material without the copyright owner’s permission. For example, in the United States, works of commentary, criticism, research, teaching, or news reporting may be considered fair use. Some other countries have a similar concept called fair dealing that may work differently.

Courts look over potential fair use cases according to the facts of each specific case. You’ll probably want to get legal advice from an expert before uploading videos that contain copyright-protected material.
