How to Make an AI Animated Short Film

Quick answer: An AI animated short starts the same way as a live-action one — a script, a cast, a storyboard — with one decision that matters more: the style. In step 1 SceneMixer offers three groups of animation presets (2D Animation, 3D Animation and Stop-motion) and the style you pick is drawn into every character sheet, location and shot, on every video tier. Choose Film as the Type for a short with room to breathe, give each character one unmistakable visual trait so animated faces do not drift between shots, draft cheaply — flat, cel-shaded looks tend to hold up at 480P better than painterly ones — and composite the finished film into one file.

Brief for AI Create: An animated short: a lighthouse robot who has never seen another robot finds a small broken drone washed up on the rocks; he spends the winter fixing it; it flies away on the first day of spring and comes back with others; gentle, wordless, hopeful.

Pick the style first, and carefully

The visual style is fixed once you continue past step 1; to try another, you start a new project with the same script. Look at the sample card for each preset before choosing:

Group	Presets	Good for
2D Animation	2D Cel Shading, Hand-painted Anime Film, Painterly Anime, 2D Chinese Style, Ink Wash Animation, Korean Webcomic, Manhua Full-render, American Graphic Novel, Watercolor Storybook, Oil Painting	Anime shorts, storybook tales, graphic-novel thrillers
3D Animation	Realistic 3D CG, Feature 3D Animation, 3D Toy Cartoon, Cel-shaded 3D, 3D CG Xianxia Fantasy, Game Engine Realism	Family films, toys and creatures, game-style stories
Stop-motion	Claymation	Handmade, tactile, often funny

Every video tier renders the style; there is no separate animation tier. The presets, one by one · Stylised looks across the tiers.

Design characters that hold across shots

Animated faces are simpler than real ones, which makes them easier to confuse: two anime girls with brown hair become one. Give every character one trait nobody else has, and put it first in the description:

A white streak in her black fringe, round glasses, a yellow raincoat she never takes off.
A short, round robot with one large blue eye-lens, a dent on his left side, rust on his feet.
A tall fox in a green scarf, one ear torn at the tip.

Sheets are drawn on a plain background with even light on purpose: they are references, not posters. The mood comes in the shots. Why sheets are plain · Robots, animals and creatures.

Write for animation

Bigger expressions. Animation reads emotion from the whole body. Delivery notes and actions can be broader than in live action: he throws both arms up, her ears flatten.
Wordless is fine. Many animated shorts have no dialogue at all. Mark those shots No dialogue and let the Ambient line carry the sound: wind, a creak, a beep.
Light as storytelling. Animation lives on colour. Write the light into each shot: the lighthouse beam sweeps across the dark sea, spring sunlight turns the rocks gold.
One action per shot. Even in a cartoon, a jump, a landing and a fall are three shots.

Beat	Shot to adapt
The discovery	[Shot 2] 4s: Medium shot, low angle. @Beacon kneels on the wet rocks and lifts the @Drone in both hands; its single light flickers. No dialogue. Ambient: waves, a faint electronic chirp.
The winter	[Shot 5] 5s: Wide shot, fixed camera, the workshop at night. @Beacon at the bench, the @Drone in pieces under a lamp; snow against the window. No dialogue. Ambient: a soldering hiss, the wind.

How to write one shot.

A storyboard segment: location, time and weather fields, then numbered shots with durations, asset chips and spoken lines — A storyboard segment: the header fields, then numbered shots with their seconds, @ chips for who is in frame, the lines and the sound.

Settings to pick in step 1

Type: Film — slower pace, no episode cap, written as one piece. Short Drama, TV Series or Film.
Aspect Ratio: 16:9 Landscape for a film; 9:16 Portrait for an animated series on phones.
Scene Style and Costume Style: they work with any visual style. A storybook village (Pastoral Healing), a sci-fi station (Starship), a magic school (Magic Academy). Set all three together; a period costume in a modern set reads as a mistake.
Region and language: pick where the world is and what the cast speaks; animated characters speak any of the dialogue languages natively.

Draft cheaply, finish the keepers

Generate the whole short on the default tier first — 10 credits a second — and watch it cut together. Flat, cel-shaded styles tend to hold up at 480P; painterly and finely textured ones usually gain more from a higher tier, so regenerate the shots that will be seen most at a higher resolution. Regenerating one segment costs only that segment. Draft at 480P, finish at 1080P.

Make it in SceneMixer, start to finish

Script: your own on Upload Script, or a brief in AI Create with the character, what they want, what is in the way and the ending.
Step 1: Type Film, the aspect ratio, and the animation style you chose from the sample cards; read the script.
Step 2: generate the cast with one distinguishing trait each, the locations and the props that recur. The first 15 setup images on an account are free.
Storyboard: read it like an animator: one action per shot, light in every shot, No dialogue where nobody speaks.
Video and finish: generate, regenerate what misses, composite, download the original. Composite and share.
