A sync license (short for synchronization license) is a type of music license that allows music to be used in synchrony with visual media such as film, television, video games, and advertisements. Here's how sync licensing works:

• Identifying the right music: Sync licensing starts with identifying the right piece of music to accompany the visual content. This could be an existing song, an original composition, or a piece of music specifically written for the project.
• Negotiating the license: Once the right music has been identified, the music's rights-holders (usually the songwriter, publisher, or music publisher) must be contacted to negotiate the terms of the license. This will typically involve discussions around the usage, the length of the license, and the fee to be paid.
• Payment of fees: If an agreement is reached, the next step is to pay the agreed fee for the sync license. This fee is usually a one-time payment for the specific usage agreed upon.
• Use of the music: Once the sync license has been granted, the music can be used in the visual content. This may involve recording the music, editing it to fit the visual content, or using an existing recording of the song.
• Royalties: After the music has been used, the songwriter and/or music publisher will typically receive ongoing royalty payments for the use of the music. These royalties are collected by performing rights organizations such as ASCAP and BMI.
• Sync licensing is a valuable source of revenue for musicians and songwriters, and it allows their music to reach new audiences through its use in visual media. It's an important part of the music industry, and it's a key factor in the success of many artists and musicians.
