In terms of filming, what does 'synchronization rights' allow you to do?

Synchronization rights grant the holder permission to use a piece of music in conjunction with a video. This is particularly important in the film, television, and advertising industries, where integrating music with moving images is common. By obtaining synchronization rights, filmmakers can align the audio of a song with the visuals on screen, enhancing the emotional impact of their work while ensuring that they are legally compliant with copyright laws.

The other options do not accurately reflect the role of synchronization rights. Recording voices refers to custom voice recordings, altering existing recordings pertains to modifying pre-existing content, and selling broadcasting rights involves granting the ability to air a production, which are different rights concerned with various aspects of content distribution and usage.
