Generate a short vertical video concept with MCP

Choose one vertical shot, not a miniature edit

Define one visual change that can read without dialogue: for example, an unopened parcel enters frame, the camera makes a restrained push-in, and the parcel opens to reveal a warm glow. Keep the subject, setting, action, camera move, lighting, and end frame in one prompt. This is a concept shot for a later edit, not a promise that the model will assemble hooks, captions, cuts, music, and a call to action.

Record `9:16` as the placement requirement, not as a verified model setting. The published OfflineCreator MCP `generate` tool accepts a model ID, prompt, shared optional ratio enum, and optional wait; it exposes no duration field. The enum proves request syntax only. This research did not observe an exact Studio ID, per-model ratio compatibility, configured duration, or completed clip for either catalog entry.

Keep duration and ratio unresolved before spending

Call `list_models` immediately before drafting the final prompt, then select a text-to-video entry and call `get_credits`. The current public catalog identifies Kling 2.6 Pro as the social-video text-to-video option at 42 credits and Veo 3.1 Fast as the premium-campaign text-to-video option at 96 credits. Treat those values as a dated preflight snapshot, because catalog capabilities and costs can change.

The disclosed fal endpoint for Kling 2.6 Pro lists `9:16` and five- or ten-second output, while the Veo 3.1 Fast endpoint lists `9:16` and four-, six-, or eight-second output. Those are direct-provider envelopes, not verified Studio configuration. OfflineCreator's published MCP does not let the caller select duration, and no first-party Studio source reviewed here binds either catalog entry to a duration or ratio. Do not add `duration`, submit a ratio, or promise a clip length from this draft.

Use a compact shot specification

Purpose

Stop the scroll with one readable revealName the single idea the shot must communicate before describing style.

Frame

9:16 placement requirementModel-specific Studio support remains unverified; no paid request is authorized by this page.

Motion

One slow camera move plus one subject actionAvoid asking a short clip to perform several cuts, locations, transformations, and camera moves.

Duration

Unresolved in StudioProvider duration options do not establish the duration configured by the Studio route.

Exit frame

A stable final compositionDescribe where the subject settles so an editor has a usable hold, transition point, or end card background.

Example: a silent-first launch reveal

Illustrative brief only: a vertical reusable-bottle reveal on a warm-black tabletop, with an unbranded bottle centered, generous overlay space, one traveling light, one restrained push-in, no captions, no logos, and no cuts. The brief intentionally omits an executable ratio value and exact duration because this research did not establish them for a Studio model. No clip was generated and no geometry, pacing, or final-frame behavior was observed.

Do not submit from this example. A future operator must first confirm the exact returned model ID, current cost, model-specific ratio support, and configured or observed duration. Narration, music, sound effects, exact typography, legal copy, and captions remain editor responsibilities; the absence of an MCP audio field does not predict whether a routed provider returns audio.

Take the next action that matches the review

If the concept needs a more formal shot-purpose and motion decision before generation, use the one-shot planning guide. If the first output is promising but needs comparison against controlled alternatives, move to a small proof set rather than scaling immediately. Return to the workflow directory when the job changes from one vertical concept to another media type.

Keep this guide inside its evidence boundary

This page owns the MCP operator workflow for a requested vertical concept: capture the placement requirement, inspect the connected schema, stop at missing runtime fields, and define the completed-file handoff. `/use-cases/short-form-video-concepting` owns upstream editorial work such as hook selection, narrative load, and campaign review. This page does not promise `9:16` support, five- or eight-second Studio output, exact geometry, final copy, or a successful clip. Because required vertical support and Studio duration remain unverified, consolidate actionable guidance into the parent workflow hub and keep this route draft.
