Criteria for a film, not a clip
| Criterion | Why it matters for a film |
|---|---|
| Project structure | A 45-minute film is several hundred shots; chapters or episodes keep them manageable. |
| Reference handling | Faces and sets must match from the first scene to the last. |
| Script and storyboard | Fixing a shot on a frame is far cheaper than fixing a clip. |
| Clip length | Longer clips mean fewer cuts per scene, but most films are cut from short shots anyway. |
| Assembly and export | You will finish in an editor; the tool should hand over clips or a draft cleanly. |
| Cost per finished minute | Video dominates the budget; see the cost answers below. |

Pick by film
- A pitch or a brand film: LTX Studio, if PDF pitch decks and animated storyboards help you sell it.
- Shot-by-shot directing with many models: Higgsfield or Runway.
- Talking-character pieces: Hedra.
- A long, story-driven film with a recurring cast: Arc. We released 8 films made with it, 234 minutes in total, including The Wolf Mother (431 clips) and The Fall of Kalak (427 shots).
Where Katechon Arc fits
Arc holds a feature as chapters that share references, storyboards every shot and assembles a cut you can download or export as a Jianying draft; our own features run 40 to 56 minutes.
Arc has fewer models than most of these tools and no free plan; for finishing (grade, score, final mix) you still need an editor.
People also ask
Can an AI movie maker turn a script into a film?
Yes, with review in between: the script becomes a shot list, each shot gets references and a storyboard frame, and then video. Expect to edit and regenerate shots.
Is there a free AI movie maker?
Free plans exist as one-time credits or trials, enough for a few clips. A feature needs hundreds of clips, which no free plan covers.
