What a stock brief is, and how to submit to one

Most stock works one way. You shoot what you like, upload it, add metadata, and wait to see what the market wants. You are guessing, and the market answers slowly.

A brief runs the other direction. The marketplace tells you what it needs, in plain words, and you submit footage that matches. Instead of guessing what sells, you are answering a stated request.

The catch is that answering a brief still takes clean metadata on every clip you attach, and that is the slow part. See how MetaMule turns a folder into a finished submission.

A brief is a buyer telling you what they need

A brief is a short posting from the marketplace describing footage it is short on. It has a title like "Slow-Mo Cinematic Moments," a code that identifies it, and usually a few lines on the look, the subject, and any constraints. Some are wide open ("shot anywhere in the world"). Some are specific about location, season, or the kind of people and releases required.

You gather clips that fit, attach them to the brief as a batch, add your metadata, and submit. From there the marketplace reviews them against the brief.

The reason to care is simple. A brief is demand you can see before you spend the effort. A clip that answers a live brief is being judged against a need someone already has, not dropped into a search result to compete with forty others on luck.

What the review statuses mean

After you submit, a batch moves through a few states, and it helps to know what each one is telling you.

• In review. The marketplace has your clips and has not decided yet. This is the normal resting state right after you submit. Nothing is wrong.
• Accepted. The clip fits the brief and is going into the library. This is the outcome you are working toward.
• Needs revision. Close, but something has to change before they will take it. Often it is metadata, a missing release, or a spec issue, not the footage itself. Fixable.
• Rejected. It did not make it. Sometimes that is the footage, sometimes it is a correctable problem you can carry into your next submission.
• Not submitted. Still sitting in the batch, not yet sent.

A wall of "In review" is not a verdict. It is the clock starting.

How to give a brief its best shot

Match the brief, not your favorites. The temptation is to submit your best clips. Submit the clips that answer the brief. A gorgeous shot that does not fit the request is a rejection waiting to happen, and you can always submit it elsewhere.

Metadata still decides what happens after acceptance. Getting accepted puts the clip in the library. Titles, descriptions, and keywords decide whether a buyer ever finds it there. A brief does not excuse thin or wrong metadata. If anything it raises the bar, because an accepted clip that no one can search for earns nothing. This is exactly the work MetaMule does for you: it writes marketplace-tuned titles, descriptions and keywords for every clip in the batch.

Handle releases before you submit, not after. If a brief allows recognizable people or private property, it will expect the releases to come with the clips. Sorting that out first is the difference between "Accepted" and "Needs revision."

Respect the specs. Format, resolution, and length still apply inside a brief. A clip that fails a technical check never reaches the part where someone judges the content.

Where this fits

A brief changes what you shoot and where you send it. It does not change the work that makes a clip sellable once it is accepted. Clean file names, marketplace-tuned keywords, correct releases, and specs that pass are exactly what a brief submission needs, the same as any other upload. That groundwork is what MetaMule is for, so the footage you submit to a brief clears review on the metadata and lands in the library ready to be found.

Shoot to the request. Submit clips that answer it. Give each one metadata a buyer can actually search, and let the review clock run.
