What Is a Sync License? A Guide for Filmmakers, Creators, and Brands
Updated: 1 day ago
You've found the perfect song for your film's closing scene, your brand's new commercial, or your YouTube series. Before you drop it into the timeline, there's a question you need to answer: what is a sync license, and do you have one?
A synchronization (or "sync") license is the permission you need to pair a piece of music with moving images. Without it, the project you've worked so hard on can be pulled from platforms, blocked from distribution, or become the subject of an infringement claim.
Over my 20+ years representing filmmakers, musicians, and brands, I've seen music clearance derail more productions than almost any other legal issue. The good news is that it's entirely avoidable once you understand how sync licensing works.
What Is a Sync License?
A sync license is a license from the owner of a musical composition that allows you to "synchronize" that composition with visual media — a film, TV episode, commercial, video game, social media video, or trailer.
The key word is composition. Every recorded song actually contains two separate copyrights:
The composition — the underlying melody and lyrics, usually owned or administered by the songwriter's music publisher.
The master recording — the specific recorded performance of that song, usually owned by the record label or the recording artist.
A sync license covers only the first. To use a specific recording, you also need a master use license from whoever owns that recording. This is where many first-time producers get tripped up: they clear the song with the publisher and assume they're done, or they get the label's permission and forget about the publisher.
Sync License vs. Master Use License
Sync License | Master Use License | |
What it covers | The composition (melody and lyrics) | The specific sound recording |
Who grants it | Music publisher(s) / songwriter(s) | Record label / owner of the master |
When you need it | Any time the song is used with visuals | Any time you use an existing recording |
If you hire musicians to re-record a cover version of a song, you still need the sync license for the composition — but you may avoid the master use license because you own your new recording.
When Do You Need Sync Licensing?
Sync licensing applies whenever music is fixed in timed relation to visual content. Common examples include:
Feature films, documentaries, and short films
Television shows and streaming series
Commercials and branded content
Video games and apps
Movie trailers and promotional clips
Corporate videos, webinars, and event recordings
Social media content for businesses and influencers
A common misconception is that a song is "fair game" if it plays for only a few seconds, or if you credit the artist. Neither is true. There's no universal "safe" number of seconds, and giving credit is not a substitute for permission. Likewise, a platform's in-app music library may cover personal posts but often does not extend to commercial or branded use — read the platform's terms carefully.
What Goes Into a Sync License?
A well-drafted sync license defines exactly how, where, and for how long you can use the music. Here are the key terms I review for clients in every music licensing for film or media deal:
Media and Distribution
Is the license limited to festival exhibition, or does it cover theatrical release, streaming, broadcast, home video, and online platforms? A festival-only license is cheaper, but if your film gets picked up for distribution, you'll need to renegotiate — often from a weaker bargaining position.
Territory and Term
Is the license worldwide or limited to certain countries? Is it perpetual, or does it expire after a set number of years? For films, I generally advise clients to seek worldwide, perpetual rights whenever the budget allows.
Type and Length of Use
Fees and terms often depend on how the music is used: background versus featured (on-screen performance), opening or closing credits, or use as a theme song. The exact timing of the cue also matters.
Fees and Most Favored Nations (MFN) Clauses
Sync fees are negotiated and vary enormously based on the song's popularity, the nature of the project, and the scope of rights requested. Watch for "most favored nations" clauses: if the publisher insists on MFN treatment, you may have to match the best fee you pay to the master owner (and vice versa), which can quickly double your budget.
Edits and Alterations
Can you edit the song, loop it, or change the lyrics? Most licenses restrict changes without separate approval, so negotiate these rights up front.
How to Obtain a Sync License in 5 Steps
Identify the rights holders. Search the databases of performing rights organizations such as ASCAP, BMI, and SESAC to find the publishers. A song may have multiple co-writers and multiple publishers — you need permission from all of them.
Identify the master owner. Check the recording's liner notes, digital credits, or label information.
Send a detailed request. Describe the project, the scene, the length of the cue, the media, the territory, and the term you need.
Negotiate the terms and fee. Rights holders may counter, limit the scope, or decline entirely.
Get it in writing. A verbal "sure, go ahead" or a casual email is not enough. You need a signed license agreement before release.
Keep in mind that sync licensing is separate from public performance rights. When your film or show airs, the broadcaster or venue typically handles performance royalties through the PROs, which is why accurate cue sheets matter.
Common Sync Licensing Mistakes to Avoid
Clearing only one side — getting the publisher's sync license without the master use license, or vice versa.
Waiting until post-production. If a key song can't be cleared, you'll have to re-edit scenes. Start clearance early.
Licensing too narrowly. Festival-only rights can become a roadblock when a distributor wants to acquire your film.
Relying on "royalty-free" labels without reading the terms. Stock music licenses often carry restrictions on commercial use, broadcast, or redistribution.
Missing a co-writer. A single uncleared co-publisher can expose you to an infringement claim.
Distributors, streamers, and errors and omissions (E&O) insurers will almost always require proof that your music is properly cleared. Getting it right from the start protects both your project and your ability to sell it.
Understanding what a sync license is only gets you halfway there.
