What it does
Create cinematic movie poster concepts and final poster images from a user's brief, existing video plan, storyboard, character design, or project context. Use this skill whenever the user asks to generate a film poster, movie poster, key art, campaign poster, teaser poster, title poster, or promotional visual for a video project. This skill proposes several creative directions first when appropriate, defaults to a 3:4 poster ratio when no ratio is specified, and ensures typography, title treatment, imagery, genre, setting, and story tone are coherent and visually inventive.
Video Poster Design
Use this skill to create movie-poster-style key art for a video, short film, vlog, TVC, storyboard, or campaign.
The final output is a poster image. When useful, also create a short poster spec or prompt file so the design can be regenerated consistently.
Default Behavior
If the user does not specify an aspect ratio, use 3:4.
If the user asks for a poster but has not chosen a creative direction, propose 3-5 poster concepts first and ask them to choose one. Keep the options concise and visually distinct.
If the user already gives a clear direction, title, ratio, and story context, proceed directly to image generation.
Output Location
Use a project-local poster directory:
posters/
Recommended file names:
posters/{poster-name}.png
posters/{poster-name}.md
Use lowercase, hyphenated, ASCII-safe names. Examples:
posters/youth-unlimited.pngposters/meaning-of-travel-teaser.pngposters/campus-energy-key-art.md
Do not overwrite existing files unless the user explicitly requests replacement. For variants, use suffixes such as -v2, -teaser, -main, -alt-a.
Inputs to Extract
Before designing, identify:
- Poster title and subtitle.
- Video/story context.
- Genre: drama, travel, romance, documentary, commercial, thriller, coming-of-age, sports, etc.
- Required aspect ratio. Default:
3:4. - Main character(s), product, place, or object.
- Character design images or approved reference assets.
- Storyboard or scene images that define visual continuity.
- Mood and emotional promise.
- Setting, time period, weather, and culture.
- Typography language: English, Chinese, bilingual, no text, etc.
- Required copy: tagline, credits, release date, brand line, campaign line.
- Output path if specified.
If the user does not specify text language, use the user's local language for any prompt/spec, and use poster typography that matches the title/campaign language.
