Creative Commons is a nonprofit organization that enables creators to share their copyrighted work with the public while keeping certain rights. The licenses provided by Creative Commons allow creators to permit others to reuse, modify, and distribute their creations under specific conditions, which are often more flexible than traditional licenses.
Vimeo gives all creators the discretion to apply Creative Commons licenses to their videos at no extra charge.
