How to use
Specify the genre, the central subject, the time of day or mood, and leave space for text ("room for title at top" / "negative space bottom-third"). Use 9:16 or 3:4 aspect for traditional poster proportions. Generate Free and pick the stronger result.
What it is good for
Fan posters · Short film and indie pitch decks · YouTube and podcast cover art · Event posters · Book covers · Mood boards for real productions · Concept pitches. Plus and Pro outputs include full commercial usage rights.
Which model to pick
For posters with text-safe negative space and dramatic light, GPT-Image-2 is the strongest baseline. Nano-Banana Pro nails illustrated or painterly poster styles (fantasy, anime tie-in, vintage). Run both, pick the better silhouette.
Frequently asked questions
Can I add my own title text to the poster?
The AI generates the image; add your title and credits in any editor (Figma, Canva, Photoshop). Ask for "room for title at top" in your prompt to leave space.
What aspect ratios work best for posters?
Traditional movie one-sheet is 27×40 inches (≈ 2:3). The 3:4 and 9:16 presets are the closest matches. Square 1:1 works for social cuts.
Can the AI generate readable text inside the image?
Sometimes — GPT-Image-2 handles short text better than Nano-Banana. For real titles you should still add text in a design tool to control font and spacing.
Are the posters royalty-free?
On paid plans (Plus, Pro), yes — commercial rights are granted on everything you generate. Free tier is personal-use only.
How do I avoid the generic "AI poster" look?
Name a director or cinematographer for lighting reference ("lit like a Roger Deakins one-sheet"), specify lens and film stock ("anamorphic, Kodak Vision3"), and pick a genre with strong visual rules.
