How to Make an AI Movie: From One Sentence to a Finished Short Film

BudgetPixel Director is an AI film director. You tell it an idea in plain words, as rough as you like, and it makes the film with you one step at a time: the story, the script, the cast, the places, a storyboard, the scenes, the music and the cut. At every step you see the work and can ask for changes.

The film at the top of this page, Tomorrow's Post, was made in Director from one sentence: "A lighthouse keeper finds a letter dated tomorrow." Below is every step it went through, with the real pictures from each one.

An AI movie maker, not a clip generator

A video generator turns one prompt into a few seconds of video. A film needs more: a story that goes somewhere, the same faces and places from shot to shot, lines spoken by the right person, music, and a cut. Director handles all of that. You make the decisions.

Step 1: Start with one sentence

Open Director, press Start, and answer "What's your film about?". One line is enough. Ours was:

A lighthouse keeper finds a letter dated tomorrow.

Step 2: Pick a story

Director comes back with three different films you could make from the idea, says which one it would pick and why, and lets you choose or ask for others. For our sentence:

• Tomorrow's Post (heart): "Every morning a 78-year-old lighthouse keeper finds a letter dated tomorrow telling her exactly what to do, and she follows it like a prophecy, until we see who's writing them."
• The Sketch (thriller): "A keeper finds a pencil drawing in his own hand, dated tomorrow, showing a boat breaking up on the rocks below his tower, and the warning is the only reason he's awake to see it happen."
• Commendation (comedy): "A lighthouse keeper who is terrified of the sea gets a medal letter, dated tomorrow, for bravery in a rescue he hasn't done yet."

It picked the first: "The letter from tomorrow ends up meaning something human instead of a puzzle to solve... It's also the simplest to make well: one woman, one kitchen." We agreed.

Step 3: The script

Every line, every shot and every cut is timed out before anything is generated, and each role is written the way an actor gets it. The script for Tomorrow's Post has six scenes and sixteen shots, and one rule: "Bronagh obeys the letter like scripture, and nobody ever says Emrys is dead." The first scene opens like this:

1.1  Wide, locked off · 3.5 s
     Blue dawn kitchen. Bronagh shuffles in from frame left in dressing gown and socks.
     The cat sits on the chair frame right. Centre: the envelope propped against the
     brown teapot. She stops.
     Sound: the wall clock ticking, loud in the quiet.
     Join: hard cut on a clock tick, straight to the envelope.

1.3  Close-up · 4 s
     Bronagh, frame left, glasses on, the unfolded letter held up. She reads aloud
     to the cat, out of frame right, solemn as church.
     BRONAGH: "Thursday. Wind the clock. Polish the lens."
     Sound: her voice over the clock tick.
     Join: hard cut to the clock, she's already obeying.

This is also where you set the film's length and shape: from 10 seconds to 3 minutes (most films land at 40 to 60), in 16:9, 9:16, 1:1 or 21:9, live action or animated. Ask for changes in plain words and the script is rewritten.

Step 4: Cast the faces

For every role on screen, Director makes three real-looking faces as close-up portraits, so you choose people, not descriptions. Once you pick, that face stays the same in every shot. You can also cast your own characters, an official BudgetPixel character, or your own photo.

Step 5: Build the world

Every place, costume and prop is made once and kept, so the kitchen stays the kitchen and the teapot stays the teapot. A note changes one thing, and your own pictures can stand in for any of them.

Step 6: The storyboard

One picture for every shot, played back as a slideshow at the length of the film, so you see the whole movie before any video is made. A note redraws one frame, for example "put her glasses on".

Step 7: Film a test scene, then the rest

Director films the scene with the most dialogue first, as a 480p draft: the acting, the voices and the cuts in one take. It checks the frames and the words, but it can't hear, so you listen. Here is the opening scene of Tomorrow's Post as a 480p draft:

When the voices are right, they carry over to every other scene, and the rest are filmed on one priced button. Nothing more is spent on video until you press it.

Step 8: Music and sound

Director writes two or three versions of a song or a score, plus the sound effects, and you pick by ear. Or upload your own track. Tomorrow's Post got a piano score:

Step 9: The cut and the finish

Director cuts the takes, the music, the joins between scenes and any title cards into the film. A note changes one thing; re-cutting is free apart from a small sound check (5 credits per started minute of film). You can download the 480p draft right there.

When you like the cut, finish it: 720p, 1080p, or 1080p filmed again, where every scene is rendered again at full 1080p from its draft. Tomorrow's Post was filmed again in 1080p. Then download it, share it by link, or make a free social version with a small watermark and a short end card.

Here is Director's launch film, which replays Tomorrow's Post's steps from the first sentence to the finished film:

What it costs

There is no single price for a film, because films run from 10 seconds to 3 minutes. Instead, each step shows its price on its button before it runs. At standard prices:

• Talking with Director costs nothing up to a daily allowance; after that, each reply shows its price.
• Re-cutting is free apart from a small sound check (5 credits per started minute of film).
• Plans: Director comes with Premium ($22 a month, 25,000 credits), Pro ($55, 60,000) and Ultra ($125, 130,000). Ultra gets 10% off the draft video, filming again in 1080p, and places, props and most storyboard frames. See pricing.

How to get a better film

• Keep the story small. One or two people, one or two places. Director picked Tomorrow's Post partly because it was "one woman, one kitchen".
• Spend your notes on the storyboard. A redrawn frame costs 120 credits (175 for a close-up on a face); a re-filmed scene costs far more. Fix the picture before the video.
• Listen to the test scene with headphones. Director can't hear its own takes; the voices you approve there carry through the whole film.
• Use the length you need. 40 to 60 seconds is where most films land, and every extra second is another second of video.
• Bring your own pieces. Your photo as the lead, your product as a prop, your song as the score: Director builds around them.

Also made on BudgetPixel, the same way

Not on a Sunday was made on BudgetPixel in the same steps Director follows: a woman in her seventies asks the greatest film director alive to make a movie about her neighbor's leaf blower, and he takes it dead seriously.
