You have a 15-second video idea and a generator window open, and you already suspect the first draft will waste your credits. The difference between an idea and a usable AI video is not a better prompt — it is a script that separates what the generator does from what the editor and the approver do. A vague script asks one tool to solve strategy, cinematography, and editing at once, and it fails at all three.
This guide is based on hands-on testing of Wan-family browser workflows and standard editorial practice. One naming note first: "Wan 3" is the browser-workflow name on this site; the publicly released model family is Wan 2.x as of August 2, 2026, and no official "Wan 3" release is listed. That matters here because this template is provider-agnostic — it works for any short-form AI video pipeline. By the end you will have a copy-paste template, a worked 15-second example, and a review loop that turns rejected clips into better briefs instead of blind retries.
Why a script, not a prompt
A prompt describes a moment; a script describes a sequence of decisions. The generator can only execute what a single shot needs: subject, action, camera, environment. Everything else — the message, the pacing, the claim, the call to action — belongs upstream in the script or downstream in the editor. When you write the script first, every rejected clip tells you something actionable: if shot two fails three times, the brief is unclear, not the tool.
Copy this template
- Audience: one sentence. Who is this for, and what do they already assume?
- One message: the single thing they should remember 24 hours later.
- Hook (0–2s): the first visual or spoken idea — the reason they do not scroll past.
- Shot cards: for each shot, five fields — objective, reference frame, subject/action, camera, transition.
- CTA: one next step. Written into the brief, placed by the editor.
- Approval rule: the measurable condition a clip must meet to ship (for example, "subject matches the reference frame, no warping, no new objects").
Shot cards in practice: a 15-second product story
Plan three to five shots, generate each as its own clip, and assemble in editing:
| Shot | Objective | Shot brief (what the generator sees) |
|---|---|---|
| 1 | Context/problem | Coffee bag on a cluttered counter, morning window light, static wide shot |
| 2 | Product reveal | Matte black canister rotates one quarter turn on a clean white surface; macro push-in |
| 3 | Proof/detail | Lid opens in slow motion; beans pour into a cup; steam rises |
| 4 | Use moment | A hand pours fresh coffee at a home desk; soft light, shallow depth of field |
| 5 | End card | Added in editing — logo, URL, offer — never generated as text |
The end-card rule is non-negotiable: keep claims, pricing, subtitles, and final branding in the editor, where a human reviews them precisely. Generated on-screen text is the most common source of unshippable clips, and it is always avoidable.
The review loop: turn rejection into briefs
When a clip fails, classify the failure before re-generating:
| Symptom | Likely cause | Fix in the brief |
|---|---|---|
| Subject changes between takes | Scene too busy | Fewer objects, or anchor with a reference frame |
| Motion warps | Too much movement requested | Reduce to one action and one camera move |
| Camera ignores the instruction | Camera instruction buried late in the text | Put camera first; remove competing motion |
| Clip feels busy | One shot doing two jobs | Split into two shot cards |
Rule of thumb: two fixes per clip maximum. If a clip needs a third attempt, rewrite the shot brief rather than the prompt — that is where the problem lives. Keep prompt syntax consistent with the Wan 3 prompt guide so your library stays debuggable.
Pain point: most AI video templates are a single prompt box, which collapses the whole production — message, shot plan, editing, branding — into one text string that cannot be reviewed or reused. Our added value: shot cards assign each job to the right stage: strategy to the script, generation to the shot brief, claims and branding to the editor. For multi-shot sequences, pair this template with the storytelling workflow.
Decision framework: single shot or sequence
| You have... | Do this... | Because |
|---|---|---|
| One approved key frame | Single shot: preserve composition, add modest motion | Fidelity beats novelty |
| A story to tell | Multi-shot with transitions | Structure carries the message |
| An idea, no visuals yet | Still-frame exploration first, then script | Cheaper to discard stills |
| Editorial with claims or pricing | Shot brief plus editor layer | Human review of facts |
Validate in one hour, not one day
- Write one shot card for your riskiest moment — the visual your approver will care about most.
- Generate a 5-second test in the Wan 3 AI generator. (5 minutes)
- Compare it against the approval rule; classify the failure if it misses.
- Fix the brief once and re-run. Two passes is enough to learn your acceptance rate.
- If the concept survives, script the remaining shots and estimate credits before the full run.
Responsible Use
A script that uses AI video responsibly is one that never lets generation outrun review. Three rules: do not use generated footage to impersonate real people or recreate real events; keep provenance — model ID, prompts, C2PA-style metadata — attached to every accepted clip so its AI origin is traceable in distribution; and never let pricing, legal claims, or accessibility-sensitive text be generated, because those are written and reviewed in the editor. If you need governance language for a policy, align the approval rule with NIST's AI Risk Management Framework.
FAQ
What is an AI video script template? A production document that separates audience, message, hook, and CTA from the per-shot generation briefs, so each stage — strategy, generation, editing — is reviewable on its own.
How many shots should a 15-second AI video have? Three to five. Fewer shots look static; more than five become too fast to review, and each additional shot multiplies your retry risk.
Should the AI generator create on-screen text? No. Keep claims, pricing, subtitles, and branding in the editor, where a human reviews them before publishing.
Can I reuse this template for longer videos? Yes. Add a beat or section field for anything over a minute, and treat each section as a scripted unit with its own shots — the same review loop applies at section level.
Write the brief before you spend the credit
You now have the template and a worked example. The cheapest next step is one shot card and one 5-second clip. Open the Wan 3 AI generator, run your riskiest visual test, and check Wan 3 pricing once you know your acceptance rate.
