Introduction
You have a logline — "a bride finds a hotel key card in the groom's jacket an hour before the wedding" — and you want the script. You paste it into a script generator, and twelve pages of dialogue come back. Good dialogue, even. Now you have to decide where the episodes break, which lines survive a 60-second cut, who is in each scene, and how any of it becomes a shot. The generator gave you a document; you needed an episode.
An AI short drama script generator is only useful if what comes out is already shaped like production: a story outline you can edit, a cast that becomes assets, episodes that break into shots. This guide shows how to use ArcLoop that way — from a one-line logline, or from a novel excerpt you want to adapt, to a multi-episode script where every line already belongs to a shot.
What a short drama script has to be
Short-drama scripts are not shorter feature scripts. They have a different shape:
- One conflict per episode, resolved or reversed by the end of it.
- A hook inside three seconds, which means the episode opens on the problem, not on the setting.
- Lines that survive muted playback — short, end-weighted, captionable.
- A cliffhanger every 60–90 seconds that makes the next episode necessary.
- A cast small enough to keep consistent: a lead, an opposition, one or two supporting characters who each have a job.
For how the arc holds across a season, the story arc guide covers the long shape. This article is about getting a shootable script out fast.
Rules for generating a script you can actually shoot
- Give the generator a logline, not a premise. "Bride finds a hotel key card an hour before the wedding" is a logline: character, discovery, clock. "A story about trust" is a premise and produces a premise back.
- Name the format up front. "Vertical short drama, 12 episodes, 60–90 seconds each" changes how the outline is cut.
- Edit the outline before the episodes. Fixing pacing in the outline costs one edit; fixing it after twelve episodes costs twelve.
- Every character in the outline becomes an asset. If a name appears in a scene, it needs a face the shots can reference with
@. - The script lives in the shot cards. The line a character says is on the card for the shot where she says it. There is no separate script document to fall out of sync.
How to generate the script in ArcLoop, step by step
- Start a new project from the logline. Open ArcLoop, paste the logline plus the format line into the input box, and send. The Agent drafts a Story Outline: type, format, visual direction, logline, core characters, synopsis.
- Set Story Settings while it drafts. Ratio 9:16 for a phone-first drama, the video and image models you plan to render with. The outline is written against these.
- Edit the Story Outline to short-drama pacing. Double-click any block to rewrite it, or ask the Agent for one change: "Move the key-card discovery into the first three seconds of episode 1." Cut any character who does not have a job.
- Turn the outline into episodes. Click New episode for each conflict in the synopsis — or ask the Agent to break the synopsis into twelve. Each episode gets its own summary; read them as a row and check that each ends on a pull into the next.
- Confirm the cast in My Assets. Every named character gets a character asset with a Main image and the references it needs. This is what lets the shots say
@Brideinstead of describing her. - Generate Shots on the first episode. ArcLoop breaks it into shot cards with description, video prompt, and the characters referenced. This is the script: one card per shot, the line on the card that speaks it.
- Rewrite the lines on the cards. Shorten to what a caption can hold. Give each line a purpose — accusation, deflection, reveal. Delete any shot that only exists to move someone across a room.
- Generate stills for the episode before video. Read the stills as a comic; if the story reads in stills, the script works. Then video, then Edit.
Adapting a novel instead of a logline
Paste the chapter, not the whole book. The Agent extracts the outline from the excerpt; you then cut it to short-drama shape: one conflict per episode, discovery in the first three seconds, the internal monologue turned into something a character does. Novels have a narrator; short dramas have a face. Every "she realized" becomes a shot where she finds the thing.
Keep the novel's cast list in the outline's character bios so the assets match the book, and expect to drop half the supporting characters. A season needs five faces the audience can track, not fifteen.
Example 1: The logline that goes in
Vertical short drama, 12 episodes, 60–90 seconds each, modern wedding thriller. Logline: An hour before her wedding, a bride finds a hotel key card in the groom's jacket pocket — and the room number is the one her sister checked into last night. Lead: the bride, controlled, refuses to make a scene. Opposition: the groom, warm and evasive. Supporting: the sister; the wedding planner who notices everything. Each episode ends on a new piece of evidence.
Example 2: One episode's shot cards, as the script
EP1 Shot 1 — Close-up, @Bride's hand slides the key card out of @Groom's jacket pocket, dressing room, an hour before the ceremony. No dialogue. Shot 2 — Medium, she reads the room number; her face does not change. Line (whispered): "Twelve-oh-four." Shot 3 — Over her shoulder, @Sister enters behind her in the mirror, smiling. Line: "You look perfect." Shot 4 — Close-up, Bride closes her hand around the card and smiles back. Cut.
Example 3: A novel paragraph turned into shots
Source: "She realized, standing in the doorway, that he had never once mentioned the trip." Shots — Shot 1: medium, @Mira stops in the doorway of @Kitchen, one hand on the frame, camera static. Shot 2: insert, the boarding pass on the counter, his name, a city she has never heard him say. Shot 3: close-up, Mira; she does not look up. Line: "How was Osaka?" Shot 4: reverse, @Daniel with his back to her, the pause before he turns.
The most common ways generated scripts fail
- Premise in, premise out. "A story about trust" produces themes, not scenes. Give it a logline with a clock.
- Episodes that resolve. Every episode wraps up and nobody needs the next one. End on evidence, not on peace.
- Lines written for the page. Three sentences a caption cannot hold. Cut to the sentence that hurts.
- Cast bloat. Nine named characters by episode 3, none of them assets. Merge or cut.
- Script kept in a separate document. The cards drift from the doc within a day. The card is the script.
A three-episode AI short drama script example
Use this fictional example to check whether each episode changes what the audience knows. It is an editable writing exercise, not a generated or tested finished film. Premise: a station clerk finds a departure order carrying her missing brother's signature, dated today. Recurring assets: @Clerk, @Supervisor, @StationOffice, and @DepartureOrder.
| Episode | Opening evidence | Choice and short dialogue | Consequence leading into the next episode |
|---|---|---|---|
| 1: The signature | The clerk finds today's order with her brother's signature | She keeps the order instead of filing it. Clerk: “He has been missing for a year.” Supervisor: “Then you know that signature cannot be his.” | After the supervisor leaves, she finds the same fresh ink on his cuff |
| 2: The explanation | Begin with the ink on the cuff, not a repeat of the whole discovery | She asks him to sign a routine receipt. Clerk: “Just sign here.” He uses his other hand and refuses to touch the order | She compares the receipt with the order; the signatures differ, but both carry the same unusual routing stamp |
| 3: The destination | Open on the matching stamp, then the station route diagram | She follows the stamped route instead of confronting him again. Clerk: “This line closed last winter.” | At the locked platform, a signal answers from the supposedly closed line; she chooses to wait for the arrival |
For Episode 1, make four shot cards: an insert of the order; the clerk asking the supervisor; his reply with the clerk listening; and an insert of the ink as he leaves. Keep each spoken line with its speaker. Confirm that the signature and ink are readable in the stills before generating motion.
In Story Outline, record the fact carried forward: the order in Episode 1, the stamp in Episode 2, and the destination in Episode 3. Reuse the same assets in the next Episode. If you change the stamp's meaning, revise the later discovery as well. The episode break should create a new question without erasing the previous answer. For the longer arc, use the story arc guide.
FAQ
Can ArcLoop generate the whole 12-episode script at once? It can draft all twelve episode summaries from the outline. Generate shots episode by episode, because each episode's edits inform the next.
Does the script generator write dialogue? Yes — the lines appear on the shot cards, in the character's voice from the bios. You will still cut them; generated dialogue runs long.
Can I paste an existing script instead of a logline? Yes. The script-to-drama guide covers that path; the difference is that your script sets the outline instead of the Agent drafting it.
How do I keep the tone consistent across episodes? Keep it in the outline's visual direction and the character bios, not in each episode. The Agent reads those every time it drafts.
Next step
Write your logline as one sentence with a character, a discovery, and a clock. Open ArcLoop, paste it with the format line, and edit the outline until the first episode opens on the discovery. Generate Shots on episode 1 and read the cards as the script — if they read, you have one.
