If you plan to include copyright-protected material in your video, you will need to seek permission to do so first. YouTube cannot grant you these rights and we are unable to assist you in finding and contacting the parties who may be able to grant them to you. This is something you’ll have to research and handle on your own or with the assistance of a lawyer.
YouTube cannot grant you the rights to use content that has already been uploaded to the site. If you wish to use someone else’s YouTube video, you may want to reach out to them via our messaging feature.
