Synchronization rights refer to the legal permissions required to use music in conjunction with visual media, such as films, television shows, or video games. This means that if a filmmaker wants to include a song in their project, they must obtain synchronization rights from the song's copyright holder, which is often the songwriter or music publisher. These rights ensure that the creators of the music are compensated for their work when it is paired with visual content. Without securing synchronization rights, using a song in a visual medium could lead to copyright infringement and potential legal consequences.
