Poster and thumbnail prompts for covers with strong focal points

Use these prompts to test focal subject, title space, contrast, and channel crop before final design.

Poster and thumbnail prompt structure

A cover prompt should make the focal subject unmistakable and reserve space for final typography.

Subject

Name the cover topic, event object, video prop, product, character, or visual metaphor.

Scene

Define the background, surface, title band, supporting props, and channel-specific crop.

Light

Choose cinematic contrast, stage lighting, bright editorial light, neon glow, or soft ambient light.

Output

State poster, video thumbnail, article cover, webinar cover, event visual, or landing page hero.
