AI Story: Writing One a Camera Can Use
Try it: read your story’s dialogue aloud with a stopwatch. If one scene runs past the seconds in the table below, it is two scenes.
Six tests a story has to pass
| Test | A story that passes | A story that fails | The fix |
|---|---|---|---|
| The lead wants something | Mara must get a letter back before midnight. | Mara is sad about her life. | Finish the sentence “she wants… before…” |
| Someone is in the way | The harbour master wants the same letter burned. | A story about a lighthouse. | Give the want an opponent; a story with no opponent drifts |
| It can be seen or heard | He tears the letter in half and drops it. | He remembers his father. | Turn the thought into an action, a spoken line or a voice-over |
| Two to four places | A stairwell and a balcony. | Nine locations in three minutes. | Merge places; each location is a picture that has to stay the same |
| A turn about every 30 seconds | The letter is addressed to someone else. | Twenty seconds of walking, then a speech. | Add new information, a shifted loyalty or rising danger |
| It ends open | Her phone lights up with her sister’s name. | They make up and smile. | Stop one beat before the answer |
The last two tests are the ones short formats live on. Writing hooks and cliffhangers covers the kinds of ending to rotate, and the one-line brief shows how to ask for them up front.
The stopwatch: seconds, words and shots
Video is bought by the second, so a story has to be counted in seconds before it is counted in pages. The numbers to plan with:
| What | Number | Why it matters |
|---|---|---|
| Spoken English | About three words a second | A twelve-word line needs about four seconds of shot, plus any movement |
| A look, a turn, a small gesture | 2–3 seconds | Shorter than that reads as a flicker |
| One line and its reaction | 3–5 seconds | The commonest shot in a drama |
| Crossing a room, an action beat | 6–10 seconds | Give movement the room it needs |
| One line of dialogue | Under about 20 words | Longer lines are cut across several shots |
| A 1–2 minute episode | 180–360 spoken words in 2–4 scenes | Where a vertical drama usually lands |
| Episode ceiling | Short Drama 240 s, TV Series 300 s, Film none | Chosen in Step 1 before the read |
So a 60-second episode is four segments of 15 seconds, and with three to five shots a segment that is twelve to twenty shots. If your scene needs forty, it is a different, longer episode. Shot seconds and timing · Vertical short drama script format · Short Drama, TV Series or Film.
The same scene, rewritten to be filmed
Before (reads well, films badly):
Mara had dreaded this for years. She climbed the stairs feeling that nothing would be the same, thinking about the day her father left, and knocked on the door, hoping he would not be home.
After (everything is something a camera can show or a voice can say):
INT. STAIRWELL, NIGHT. Mara, in a wet jacket, checks a door number against a letter and knocks twice.
Teo (through the door): Who is it?
Mara (steady): Your father’s courier. I have something you were not supposed to get.
The chain slides. A crack of light falls across her shoes.
What changed: the dread became an action (checking the number) and a line (“you were not supposed to get”); the memory of her father became a connection the viewer learns from the dialogue; the ending is a door opening, not a feeling. Lines written as Name (delivery): words are carried into the storyboard word for word, while speech folded into narration is only summarised. Write dialogue so it is picked up.
A three-episode shape to copy
| Episode | Opens on | Turns | Ends on |
|---|---|---|---|
| 1 | A ticket scanner beeps: name already used | The passenger knows a nickname only the deckhand’s late brother used | A reveal: the ticket was bought yesterday |
| 2 | The deckhand follows the passenger onto the car deck | The passenger is not alone; the ferry captain is in on it | An arrival: a phone rings in the brother’s old locker |
| 3 | The locker, open | What the brother hid is not money but a recording | A turn: the voice on the recording is the captain’s |
Notice that each episode opens in the middle of the conflict and ends on a different kind of question, and that the whole story needs one ferry and two or three people. That is a small cast on purpose: every character needs a picture and a voice that stay the same, and every extra place needs its own. The same face in every shot.
What to leave out of an AI story
- Readable text as a plot device. A letter, a sign, a text message, a price: video models do not draw legible words reliably. Let a character say it. Text on screen: fixes.
- Real people and famous characters. The IP check refuses a picture or a clip that resembles a real person, a brand mark or a known character, so invent your own cast.
- Crowds and brawls. AI video does best with a few named people and one clear action a shot; wide shots of many people tend to blur, so cut between close shots. Writing fights, crowds and group scenes.
- Time jumps carried by a caption. A caption line is kept in the storyboard but is not drawn in the clip at the moment, so say the jump in a line (“Three years later, and you still have the key”).
- Thoughts. Use a voice-over line or a look held a beat longer.
Letting AI write it, then checking it against the tests
You can write the story yourself, paste it, or give AI Create one or two sentences and read what comes back. The six tests work the same on a machine draft: read it for the want, the opponent, the places and the ending before you press the button that reads it. If a test fails, the quickest fix is a sharper brief or an edit to the script, both of which cost far less than a video. AI story generator shows what the draft turns into, and AI story writer shows who decides what.
Make it in SceneMixer, start to finish
- Script: paste your own on Upload Script, or write the brief above in AI Create and let it draft the episodes.
- Step 1: Type Short Drama; Scene Style Neon Nights, Urban Opulence; Costume Style Smart Casual, Streetwear; Visual Style Digital HD, Soft Glow; Target Region; dialogue language; 9:16 Portrait. Then read the script.
- Step 2: check that the two or three people you wrote are the whole cast, and that each place is one you meant. The first 15 setup images on an account are free.
- Storyboard: generate episode 1 first (free on your first drama) and read it before you render anything. One place per segment.
- Video: render on the default tier at 10 credits a second, fix single shots instead of whole episodes, then put the episode together and post.
FAQ
What is an AI story?
A story written with the help of an AI model, here meant to be filmed: it becomes a script, a cast and a storyboard, then a video.
What kind of story works best as a video?
One with a lead who wants something, an opponent, events a camera can show, two to four places and a turn before each episode ends.
How long should a scene be?
A vertical drama episode of one to two minutes usually holds two to four scenes and 180–360 spoken words, at about three words a second.
Can I use my own story?
Yes. Paste it or upload a .txt, .docx or .md file. Dialogue written as Name: line is kept word for word; speech inside narration is summarised.
Why does my story need so few characters?
Every character gets a picture and a voice that are used in every shot, and each extra place needs its own picture. Two or three characters carry a short story.
Can a story rely on a letter or a sign?
Not reliably. Video models do not draw legible text, so put the words in a spoken line.
Does the story have to end on a cliffhanger?
In a short drama series every episode except the last should end on an open question. A film can end quietly.
Is it free to try a story?
Writing is priced by length, reading is 4 credits per 1,000 characters, and the first drama gets 15 free setup images and a free episode 1 storyboard.
Test your story before you shoot it
Paste it, read the cast and the first storyboard, and fix the text while it is free.
