AI storyboard generator: how we go from one script to six rendered scenes

Every "AI storyboard generator" ranking on page one of Google is a list of ten tools that will turn a script into a set of frames and leave you there. Which is useful for a pre-production pitch deck, and useless for the thing most creators actually want: six rendered scenes they can post, with a locked character, this week.

Here's the workflow we actually run. Script to storyboard to rendered video, inside one studio, with every step priced in credits. If you've never shipped an AI video from a script, this is the fastest path through it; if you have, the numbers will tell you where your current chain is leaking money.

What a storyboard is, in our workflow

A storyboard, for our purposes, is not a sketched page of panels. It is a scene list — six to twelve rows, each row with a one-line description, a camera note, a character tag, and a target length. The storyboard tools in the SERP generate the sketch, which is useful for showing a client. The scene list is what the engine actually reads.

The writer in our studio drops that scene list from a script, a bullet list, or a loose idea. It costs five credits per action — a draft, a tighten, a shift, a next part. One generation is five credits; a stuck-and-restart on the same scene is another five. On the cheapest plan that's five cents per iteration. Writing is deliberately cheap on this shelf because the rest of the chain isn't.

The reason the writer isn't the storyboard tool: the useful output is text the engine can read, not frames the client can approve. Those are two different artifacts and we price them separately. If you want frames, the first scene from the draft pass below is what prints them.

The three-pass chain, with credit math

I budget per finished clip, in three passes. Draft, hero, signature. Each pass is a specific engine, a specific resolution, a specific tolerance for retakes. The number at each row is what the engine picker prints before you press render.

Draft pass. Seedance 2.0 Fast at 480p, 25 credits a second. A fifteen-second shot is 375 credits. If the storyboard works, you keep going; if the shot is wrong, you've spent about four dollars finding out instead of fifty. The point of the draft pass is to learn whether the storyboard is right, not whether the engine is good.

Hero pass. Kling O3 Pro or Veo 3.1 Fast at 720p, voiced. 450 credits per fifteen seconds on Kling, 240 per eight seconds on Veo. One retake per three scenes is realistic; count on a 1.3x multiplier on the hero-pass credits across a whole episode.

Signature shot. Seedance 2.5 at 720p for the one shot the whole clip hangs on. 1,050 credits per fifteen seconds. One per 90 seconds, not every scene. The premium is per-shot, not per-episode.

A 90-second finished video on this chain lands around 5,000 to 7,000 credits, most of it in the hero pass. The draft pass is what keeps the number down: you find out the storyboard is wrong for 375 credits instead of 1,050.

The full chain priced on a six-scene episode

Six scenes, 15 seconds each, one locked character, voiced, 9:16 vertical, 720p. The numbers are from the engine picker on our shelf, printed before you press render.

step	what you buy	credits	about USD on Lite
writer: scene list from a script	one convert action	0 (convert is free)	$0
writer: three tightens	3 × 5	15	$0.15
character sheet	one locked identity	20	$0.20
draft pass, six shots, Seedance 2.0 Fast 480p 15s	6 × 375	2,250	$22.50
hero pass, five shots, Kling O3 Pro 720p 15s voiced	5 × 450	2,250	$22.50
hero retakes, 1.3x on hero	0.3 × 2,250	about 675	$6.75
signature shot, one Seedance 2.5 720p 15s	1 × 1,050	1,050	$10.50
export	one 9:16 MP4	20	$0.20
finished 90-second episode		about 6,280	about $62.80

On the Creator plan at 0.75c per credit the same episode is about $49. On Studio annual, under $37. The spread across plans is the thing nobody in the storyboard-tool SERP will show you, because they don't own the engine chain — they stop at frames and leave the rest to a video tool you'll have to figure out separately.

What the storyboard tools actually do, and where the gap is

The leading storyboard tools in the SERP — Storyflow, Shootsta, M Studio, ZSky, Adobe Firefly's storyboard mode, Storyboarder.ai, Boords — all do the same thing well. Parse a script, generate panels, print a shot list, let a team collaborate. Every one of them stops at the panel.

What they don't do is price the render that comes after. A storyboard with six panels is six video renders waiting to happen; the finished-clip credit math is where the storyboard decision actually becomes a cost. A shot that works at Veo 3.1 Fast's 8-second cap costs a quarter of the same beat on Seedance 2.5 at 720p. A scene with two characters in frame is a Kling scene; a scene with one locked character and a 30-second monologue is a Seedance 2.5 scene. The storyboard tool can't price any of that, because it doesn't know what engine you'll render on.

Our writer drops the scene list straight onto the engine shelf. The picker quotes each scene on each engine before you press render. The storyboard decision stops being "which panel is right" and starts being "which panel on which engine at which length". That is the step the SERP tools don't do.

A worked example: one 90-second product video for a software app

A real brief, lightly disguised. A SaaS app wants a 90-second product video with one on-screen presenter, 9:16, voiced, no face capture (presenter is the brand's mascot — an animated character). Six scenes, 15 seconds each.

• Scene 1: establishing beat. The mascot pushes a laptop lid closed, says one line into camera. Veo 3.1 Fast, 8 seconds trimmed to 15 is the wrong shape; this is a Kling shot. 450 credits voiced at 720p.
• Scene 2: feature demonstration. The mascot's hand holds a phone, screen inside the phone shows the app. Long camera dolly across the shot. Kling. 450.
• Scene 3: reaction. The mascot's expression changes from frustrated to relieved. Veo 3.1 Fast, 8 seconds, native audio catches the sigh. 240.
• Scene 4: the signature shot. The mascot opens a door into an animated office, continuous 15-second take, 1080p. Seedance 2.5. 1,350 at 720p, 3,225 at 1080p. We pick 720p (phone screen) — 1,350.
• Scene 5: two-shot with a colleague. Second named character. Kling's element tagging binds two identities to two bodies. 450.
• Scene 6: closing beat. Mascot walks into frame, says the tagline, 8 seconds, locked camera. Veo 3.1 Fast at 240 credits.

Plus the draft pass across all six (6 × 375 = 2,250), character sheets for both characters (40), writer at 15 credits, export at 20, and about 650 in hero retakes. Finished at around 5,815 credits — about $58 on Lite, $44 on Creator.

The number is specific because the engine chain is specific. On any single-engine shelf you'd pay somewhere between double and triple that for the same 90 seconds.

The two mistakes new creators make

They render the storyboard before they test the storyboard. The draft pass is the whole point of a cheap engine. 25 credits a second at 480p — a fifteen-second shot in draft is 375 credits. Skip that step and you pay 1,050 per shot in the signature engine for a storyboard you'd have torn up for 375.

They skip the writer. The writer is free on convert (because converting a long brief into a scene list is the only path out of a brief the engine can't read) and five credits elsewhere. People who hand-write their scene lists spend ten times longer and ship clips with the same mistakes the writer would have fixed. Not a tool for people who can't write — a tool for people who want to ship this week.

The honest part

A storyboard is a prediction about what will render well. The prediction is cheap on this chain and expensive everywhere else. Our 9.7 million views across 30 days on @cevrico came from running this three-pass chain on every clip we posted: draft pass to kill bad storyboards, hero pass on the format that works, signature shot on the one scene a week we really wanted people to clip. Own results, not a projection; your numbers will depend on what you make.

A free account comes with 300 credits — enough for one draft pass on a four-second shot, a character sheet, and the writer running three times before you spend a dollar. Pick a script and run it through the chain.
