Sync Prompt Generator

How Sync Briefs Work: A Practical Guide to Writing Music Supervisor Prompts

A single national TV commercial placement can pay $20,000 to $550,000 upfront, according to 2026 sync fee data aggregated by Chartlex from disclosed deals, library rate cards, and supervisor interviews. To put that against streaming economics, you need roughly 250,000 streams to clear $1,000 at independent payout rates. One cue placed against the right scene can out-earn a year of streaming for an independent artist. The gate to that income is the brief, the short document a music supervisor sends when they need music for a scene, spot, or campaign.

This generator assembles brief-shaped paragraphs from curated variable lists so you can practice the format, run songwriting camp exercises, or hand a collaborator a stack of prompts to work through. It is not a real request from a working supervisor. It is a training tool that mirrors how real briefs are written, so you can train your ear for the form and generate creative constraints on demand.

What a Sync Brief Actually Contains

A brief is a structured request, not a freeform wish. The variables below are the ones that show up in almost every brief a supervisor sends, and they are the same variables this tool mixes and matches.

Use case. The medium the music is for: trailer, TV drama, TV comedy, video game, commercial, documentary, corporate video, feature film, or podcast intro. The use case sets the budget ceiling, the clearance speed the supervisor needs, and the kind of emotional register that reads on that medium. A trailer brief and a corporate video brief are not written the same way.

Genre and mood. Supervisors rarely ask for a genre in isolation. They ask for a mood inside a genre, like “brooding indie folk” or “euphoric synthwave.” The mood is what the scene is built around. The genre is the sonic lane that delivers it. This tool pairs a mood from a list of 30 with a genre from a sync-relevant list of 40 so the combinations stay plausible.

Energy and tempo. A brief usually specifies an energy arc or a tempo range, sometimes both. “Builds steadily from a sparse intro into a driving second half” is an energy arc. “110 to 130 BPM” is a tempo range. The energy phrase tells the composer or curator where the cue should sit dynamically against the picture.

Vocal policy. Score, trailer, and background cue work often specify instrumental only, with no vocals. A featured vocal placement asks for lyrics that align with the scene. The instrumental toggle in this tool mirrors that distinction. When instrumental only is selected, the generator drops the lyrical theme line, since there are no lyrics to align with the picture.

Reference style. Many briefs include a reference artist or era to communicate a sonic neighborhood, phrased as “in the style of” or “in the vein of.” This describes a direction, not a reproduction. It is normal industry language and is not a copyright concern on its own. The reference field in this tool lets you add that direction in the same phrasing a supervisor would use.

How the Generator Assembles a Brief

The tool holds separate arrays for use cases, genres, moods, energy phrases, and lyrical themes. On generate, it picks one value from each array, either at random or from the values you locked in the advanced options. It then picks one of six sentence-structure templates and feeds the selected values into that template as a paragraph.

Six templates exist so the output does not read as visibly repetitive. One template opens with the mood and genre, another frames the ask as a scene that needs music under dialogue, another reads as a one-line brief header followed by detail, and so on. Each template handles the optional pieces conditionally: the lyrical theme line only appears when the brief allows vocals, and the reference clause only appears when you supplied a reference style. That conditional logic is what keeps the output coherent whether you run it fully randomized or with every variable locked.

Batch generation runs the same process 5 or 10 times with a fresh template and a fresh variable draw each time, with light deduplication so a batch does not contain near-identical prompts. The result is a stack of distinct briefs you can work through in a single session, which is the use case for songwriting camps and practice drills.

Real Fee Ranges by Medium (2026 Data)

The fee a placement pays depends on the medium, the placement type, the term, the territory, and whether the deal is exclusive. There is no statutory minimum for sync in the US or Canada, so every fee is negotiated. The ranges below are market-observed bands for 2026, drawn from the Chartlex rate card and corroborated by SyncPlacement and Velveteen FM industry guides. Treat them as where deals tend to land, not as guarantees.

• Indie short film: $0 to $1,500 combined sync and master. Often festival-use-only or deferred, traded for a credit and festival rights rather than upfront money.
• Network TV episode: $3,000 to $45,000 all-in. A featured vocal moment sits at the top of that band, a background cue at the bottom.
• Streaming original (Netflix, Apple TV+, HBO): $10,000 to $75,000 or more. Worldwide, all-media, in-perpetuity terms push these toward the top.
• National TV commercial: $50,000 to $500,000 or more for a recognizable song. A major brand running a global campaign can clear seven figures.
• Studio film trailer: $100,000 to $1.5 million for a hit-driving needle drop. Indie trailers run far lower, often $1,000 to $5,000 as a flat fee with no backend.
• AAA video game: $15,000 to $150,000. Indie titles run $500 to $5,000, with buyout structures common.

The upfront fee is only half the equation. When the show airs, your performing rights organization collects performance royalties on the composition. A modest TV cue with strong reruns can quietly out-earn a one-time big check over time. Before you accept any offer, run the deal terms through the Sync Licensing Fee Calculator to benchmark the number against the medium and placement type.

Reference Style Phrasing and Copyright

The reference artist field exists because real briefs use reference language constantly. A supervisor might write “in the style of Fred Again..” for a club scene cue, or “reminiscent of early 2000s indie rock” for a coming-of-age montage. The Guild of Music Supervisors and the libraries that feed briefs treat this as standard practice. The phrasing describes a sonic neighborhood. It does not copy a composition or a master recording.

The line to hold is between direction and reproduction. “In the style of early Cage the Elephant” is direction. “Sounds exactly like” a specific track is a reproduction ask, and that is where copyright and likeness issues start. This tool uses the direction phrasing by default. If you are responding to a real brief that includes a reference, match the energy, tempo range, and instrumentation the reference points at, not the reference itself.

From Generated Brief to a Real Pitch

A generated brief is a starting point. The practical workflow is to generate a batch, pick the one or two prompts that spark something, and turn them into a writing constraint. Pin the brief to the top of your session notes before you open a session. The brief shapes what the track is allowed to be, the same way a title does. If you need a title that fits the brief first, run the central image or mood through the Song Title Generator to get candidates that signal the right emotional register before a single note plays.

Once you have a finished track that matches a brief, the next step is a clean pitch. Supervisors reject submissions that are missing metadata, have no instrumental version, or have unclear splits before they ever listen. Prepare stems, an instrumental, and clean metadata (title, BPM, key, mood, composer credits, ISRC if released) before you pitch. Use the Playlist Pitch Email Generator for the structure of a short, specific pitch email, and document your splits with the Royalty Split Sheet Generator so the clearance chain is fast. If you want to model what the placement is worth before you negotiate, pair the brief with the Publishing Royalty Split Calculator to see how the composition side of the income separates from the master side.

The discipline that protects your access to future briefs is responding only with tracks that genuinely match the ask. A supervisor who sent the brief to a handful of trusted sources is testing whether you read it carefully. Send three perfect-fit tracks and you build trust. Send fifteen “close enough” tracks and you stop getting briefs. This generator exists to train that judgment, so when a real brief lands, you already know how to read it.

Frequently Asked Questions

Can I use these generated briefs in a real pitch?
Use them as writing prompts and practice material, not as a real supervisor request. The output reads like a brief, but it did not come from a working supervisor. If you are pitching a real track to a real supervisor, write or adapt the pitch to their actual project, reference their actual show or spot, and send only tracks that fit.

Why do some briefs drop the lyrical theme line?
When the vocal policy is set to instrumental only, there are no lyrics to align with the picture, so the lyrical theme clause is removed. This mirrors how real instrumental briefs are written. They specify mood, tempo, and instrumentation, and they leave lyrical content out.

How is this different from a random word generator?
A random word generator pulls from a vocabulary list with no regard for how briefs are actually structured. This tool uses six sentence-structure templates drawn from real brief patterns and constrains the variables to values that show up in sync work. The output stays coherent and usable rather than arbitrary.

Does the tool store my favorites or reference text anywhere?
Favorites are stored only in your browser's localStorage. Nothing is sent to a server. The reference style text you type is used only to assemble the current brief and is not persisted unless you save the resulting brief to favorites.
