Synchronization licensing, also known as sync licensing, is the process of obtaining the right to use a specific piece of music in synchrony with visual media such as a film, television show, advertisement, video game, or other form of media. The license is granted by the owner of the music or the representative, such as a music publisher, and it allows the licensee to use the music as a soundtrack to their media. The terms and fees for sync licenses are negotiated between the licensee and the music owner and can vary greatly depending on various factors such as the type of media, the length of usage, and the popularity of the music.
