AI Hand-Drawn Animation Key Visual Generator
One sentence becomes the frame that sells the film — painted, on-model, and ready to art-direct from.













A key visual is one frame. The world behind it is the work.
Neta Studio is an AI world builder: a cast, a style and a set of places that stay put while you make things in them. A key visual is the smallest thing a world can produce — and the one that decides whether anyone watches the rest of it.
- One cast, every frame. The world keeps the character designs, so frame twenty still has the face and the coat from frame one.
- The style is a line you can paste. One written brief holds palette, brushwork and grain across scenes — and across different worlds, as the nine frames above show.
- A frame can grow into a world. Every still lands as a work in the world. Storyboard it, roleplay in it, or turn it into the trailer next.
There is no exact key-visual skill in the catalogue yet, so nothing here hides behind a preset — the button sends a written brief: style line, scene, composition and the on-model constraint.
Key visual questions
What counts as a key visual?
The one frame a film is sold with — poster, thumbnail, pitch deck. It has to carry the cast, the palette and the mood at once, which is why it usually takes a senior artist a week.
Can I use my own cast, or only existing shows?
Both. Build or import the characters into a world first, then name them in the prompt; their faces and outfits come back with every frame. The Genshin, Horimiya and Demon Slayer frames above are existing casts, drawn from their own worlds.
How do I keep ten frames in the same style?
Reuse the style line and only change the scene. The one in the box — gouache and ink-wash, canvas grain, visible brush edges, limited palette, matte light — is enough to hold a whole set together.
Is this a still or an animation?
A still. One 3:2 poster frame per ask. Motion is a later step: lock the look first, then animate the shot you actually want.
What size do I get?
1536×1024, 3:2 — enough for a deck, a thumbnail, or a 4K poster after an upscale. Ask for another ratio in the prompt if your film is scope.
Can it put the title on the poster?
Ask for the frame without type. Generated lettering still wobbles, so the frame is built to leave clean negative space and you set the title in your editor.
What if one frame comes out wrong?
Regenerate that frame alone. The style line and the character reference stay the same, so the replacement still matches the eight around it.
What should I type first?
A place, a person, and a moment. "A girl under the school gate in summer rain, wet yard reflecting an orange sky" is already enough.
Paint the frame people remember.
One sentence in, one key visual out. Your cast, your palette, 3:2.
