After you submit a video for monetization, YouTube may ask you for additional documentation demonstrating how you own commercial use rights to all elements in your video. This includes (but is not limited to) music, photographs, movie and video game footage plus more.
The written permission should either be a contract between you and the rights owner, or a letter from the rights owner stating that you are permitted to use their content commercially. Elements you may want to include in this documentation include:
- Explicit permission to use the rights holder’s content commercially.
- Limitations/conditions concerning your use of content specified by rights holder, if applicable.
- The URL of your video or, if you use the content in multiple videos, your channel name.
- Electronic signature with date (this can be as simple as the rights holder writing out his full name at the bottom of the document).
