Prompt: reveal a keyline around one focal object

Use this prompt when a dense composition needs one clear focal region. A keyline can guide attention without turning the rest of the scene into unreadable darkness.

Who this is for: Motion producers writing precise creative and educational briefs.

What to prepare

  • Complete composition and selected region
  • Reading order and essential context
  • Outline clearance and caption-safe areas

Copyable creative brief

An authored planning example. Replace illustrative details with your approved product facts and assets.

Plan a 15-second emphasis study for COMPOSITION. Begin with a readable overview that establishes all necessary context. Identify FOCUS_REGION by its actual boundaries and message role. Reveal one restrained KEYLINE around that region without covering text, touching unrelated objects or implying a data boundary that does not exist.

Keep the rest of the composition visible at supporting contrast. Do not blur, erase or heavily dim information needed to interpret the selected region. Allow the keyline to settle before introducing EXPLANATION. Use one primary emphasis event at a time; stop decorative motion that competes with the outline.

Finish with the selected region, explanation and surrounding relationships visible together. If the focus is a relationship between objects, outline the relevant group or use a clearly labeled connector rather than arbitrarily selecting one object. Inspect the keyline at compact playback size and in its widest motion state. If it collides with content, revise its path or create a separate detail view.

Make it your own

COMPOSITION
Supply the approved complete scene without hidden or invented elements.
FOCUS_REGION
Specify exactly what the viewer should inspect and why.
KEYLINE
Define stroke, clearance, path and resting bounds.
EXPLANATION
Use a short statement supported by the selected content.

Fill the attention problem

In an illustrative four-part diagram, emphasize the chamber while retaining inlet, valve and outlet labels. The keyline sits outside the chamber boundary with enough clearance to avoid looking like an additional wall. A short label explains the chamber's approved role.

Adapt to grouped information

If the point concerns the chamber-to-valve connection, frame both parts and their connector. For a compact composition, remove decorative background detail before dimming essential labels. A static outline may be sufficient when motion itself adds no useful reading cue.

Correct excessive isolation

If viewers cannot tell where the highlighted part belongs, restore the overview. If the outline appears to be a selection control in a fictional interface, clarify that it is an editorial annotation. If the keyline races around the scene, shorten its travel and prioritize the settled reading state.

Review checklist

  • The outline names one meaningful focus region.
  • Necessary context remains readable.
  • The keyline does not invent a structural boundary.
  • The explanation waits for a stable emphasis state.
