How to Make an AI Animated Short Film, Step by Step
Make an animated short film with AI, from logline to final cut: script, look, characters, storyboard, animatic, keyframes, clips, sound and edit, with real examples from a sample production and a token budget.
A short film is the best first AI production: long enough to tell a real story, short enough to finish. This guide walks the whole process from logline to final cut, with real pictures from Kestrel Bay, a sample series we made in Cinemagiq to show the product. The pilot follows a young man who arrives in a foggy harbour town and climbs to its lighthouse.
1. Start with one clear idea
Shorts live or die on focus: one character, one want, one turn. Write a logline before anything else, one sentence with who, what they want and what stands in the way. If the logline needs two sentences, the film is too big for a short.
Resist world-building. A strong short is a single clear moment, not a compressed feature.
2. Write the script
Turn the logline into a few scenes with clear action lines and little dialogue. Every line of dialogue is a shot that has to be voiced and lip-timed, so cut what the pictures can say. AI can help you draft and tighten, but keep the voice yours. Lock the script before you generate anything: every later step is cheaper when the story is settled. More in the AI screenwriting guide.
3. Set the look
Decide the style before the characters: photoreal, painterly 3D, flat 2D, pencil. Write it down in one short style guide with a few reference images, and use it for every generation. A short with three looks feels like three films.
Then make the locations. Kestrel Bay has four: the harbour, the cliff road, the lighthouse and its lamp room. Each one is a reference image that every shot in that place starts from.
4. Design the characters
Make one approved image of each character, then a turnaround sheet from it: front, three-quarter, side and back, in the same outfit and light. The turnaround is what keeps a character the same person in every shot, the hardest problem in AI animation. More in consistent characters.
5. Plan the shots
Break each scene into shots in a shot list: size, angle, movement, a line of action and the length you expect. A two-minute short is usually 20 to 40 shots. Then storyboard them. Rough pencil is enough; the panel only has to show who is in frame, where the camera is and what changes.
6. Time it as an animatic
Put the panels on a timeline with a temp voice, music and a few sound effects, and watch it full screen. This is where the film's pacing is found, and where shots get cut before you pay to make them. The worked example is in how to make an animatic.
7. Make the keyframes
Turn each surviving panel into a keyframe: a finished still of the shot's first frame, made with the location and the character's turnaround as references. Keyframes are where you fix the composition, the light and the faces, while changes are still cheap stills and not clips.
8. Animate the shots
Animate each keyframe into a clip of the length the animatic gave it. Starting from a keyframe instead of a text prompt keeps the look and the character: the first frame is already right, and the model only has to move it. Choose the model per shot:
| Shot | A good fit | Why |
|---|---|---|
| Long walk, slow reveal | Kling 4.0 or Seedance 2.5 | Single clips up to 30 seconds, with sound |
| Must end on a set frame | Kling O3 | First and last frame together |
| Hero shot for a big screen | MiniMax H3 | Up to 4K |
| Quick drafts for timing | PixVerse C1 or Gemini Omni 1.1 Flash | The cheapest per clip |
Review every take against the keyframe and the turnaround. Retake the misses, but don't chase perfection on the first pass: block the whole film roughly, then upgrade the shots that matter.
9. Add voice, music and sound
Generate voiceover for each line, a score and the sound effects that carry the scene. Some video models make sound with the picture; for a short you will usually want your own mix anyway, so the dialogue and the music stay consistent from shot to shot. Sound does half the emotional work of a short. More in AI voiceover and sound design.
10. Cut, watch, fix, export
Put the clips and the audio on a timeline in the order of the animatic. Trim, add transitions where they help, and watch it cold. Fix what drags, swap in the retakes, and export the film as one file.
What a short costs in tokens
A worked example for a 24-shot, two-minute short in Cinemagiq, with two takes of every keyframe and every clip:
| Item | Count | Tokens each | Tokens |
|---|---|---|---|
| Keyframes, Nano Banana Pro at 2K | 48 | 24 | 1,152 |
| Clips, Kling 4.0, 5 seconds at 1080p | 48 | 180 | 8,640 |
| Music, ElevenLabs Music, 36 seconds | 4 | 44 | 176 |
| Total, before voice and effects | about 10,000 |
Storyboard panels, character sheets and locations add a few hundred more. Cheaper models, 720p clips and fewer retakes bring the total down a lot; the Generation Studio shows the price of every generation before you run it.
Mistakes to avoid
- Generating before the animatic. You pay for shots that get cut.
- Text-to-video for characters. Start from keyframes made with the turnaround, or the character changes from shot to shot.
- Several looks. One style guide, used everywhere.
- Files in five places. Keep the script, the references, the shots and their versions in one project, or the wrong version ends up in the cut.
How to do it in Cinemagiq
Cinemagiq keeps the whole short in one project. Write the script in Docs, keep characters and locations versioned in the Asset Hub, plan every shot on the Production Board, time the panels on the Storyboard timeline, generate keyframes, clips, voice and music in the Generation Studio, fix frames in the Editor Studio, and cut and export the film in the Video Editor. Steve, the project's AI agent, can plan the work across all of it, and nothing runs until you approve it.

Frequently asked questions
How long does it take to make an AI short film?
A polished one to three minute short takes a few days to a couple of weeks for one person, depending on the number of shots and how much you iterate. The script, the look and the storyboard take the most thought; generation and assembly go fast once the plan is locked.
Do I need animation experience?
No. You direct rather than animate frame by frame: you write the story, plan the shots, choose the look and approve the takes. Editing and pacing instincts help more than drawing skills.
How many shots does a short film need?
A two-minute short usually has 20 to 40 shots. Plan them as a shot list first, then storyboard the ones that need a picture to be understood.
What does an AI short film cost?
It depends on the number of shots, the models and how many takes you make. In Cinemagiq a 2K keyframe with Nano Banana Pro costs 24 tokens and a 5-second 1080p clip with Kling 4.0 costs 180 tokens, so a 24-shot short with two takes of each keyframe and clip lands around 10,000 tokens, plus a few hundred for voice and music.
Which AI video model is best for an animated short?
Pick per shot. Kling 4.0 and Seedance 2.5 make long takes with sound, Kling O3 hits an exact first and last frame, and MiniMax H3 renders at up to 4K. For stylised 2D or 3D looks, start from keyframes in that style and animate them, so the style is set by the picture, not the prompt.
