How do you turn a script into a video with AI?

Q: How do you turn a script into a video with AI?

Break the script into shots, give every character and location a reference image, storyboard each shot, generate one clip per shot and assemble them in order with the dialogue. Tools that paste a script into a single prompt produce one clip, not a scene.

From script to shots

A script is written in scenes; video models work in shots of a few seconds. The key step is the breakdown: each scene becomes a list of shots, each with framing, who is in frame, the action and the line spoken. A two-page scene is typically ten to twenty shots.

One script line, broken down
Shot	Framing	Action	Dialogue
1	Wide, night, market square under two moons	The king's guard enters with torches	—
2	Medium on the herbwoman at her stall	She looks up, stops working	—
3	Close-up on the captain	He points at her	"That one."
4	Over-the-shoulder from the herbwoman	The crowd parts	—

The workflow

Load the script as source text. In Arc, the agent drafts a script plan per episode and you confirm it.
Create references for each character, location and prop the script names.
Generate a storyboard frame for each shot and fix what is wrong there.
Render each approved shot as a clip of 4–15 seconds. Dialogue is generated with the clip on Seedance 2.0 models.
Assemble the clips in order, check the audio and captions, and export.

Writing scripts that generate well

One action per shot, and a concrete light source.
Short lines of dialogue, one speaker per shot where possible.
Describe what the camera sees, not what a character thinks.
Name colours on the environment and wardrobe, never on skin.
Keep recurring places to a handful; each is another reference to maintain.

What it costs

Per shot in Arc: a storyboard frame is 13 credits and a 10-second 720p clip is 94 credits on Seedance 2.0 Mini, 226 on Fast and 751 on Seedance 2.0. A 15-shot scene of 8-second clips on Mini is about 1,335 credits with boards.

Where Katechon Arc fits

Arc is built around this flow: script plan, references, storyboard, then video per shot, with the plan as a review gate before any video is generated. See script to storyboard on our use-case pages.

If you want a quick narrated slideshow with stock footage from a script, faceless-video tools do that faster; Arc generates every shot and has no stock library.
