AI Storyboard Generator: Plan the Sequence Before You Render
Generating shot by shot is how AI video projects run out of credits. A shot list turns it into a plan where each generation has a job.
Without a shot list, AI video becomes a loop: generate something, decide it does not fit, generate again. Each attempt is cheap, which is exactly why the total gets expensive.
OpenFilmo turns a script into a sequence of shots with framing, motion and duration against each, so every generation has a defined job and a place in the cut. It is the cheapest way to reduce the number of renders a project needs.
What it does
Built for this specific job, not a generic generator.
Script to shot list
Beats become shots with framing, motion and length assigned to each.
Fewer wasted renders
Each shot has a job before it is generated, so fewer clips end up unused.
Continuity planning
Subject, wardrobe and lighting can be held consistent across shots on purpose rather than by luck.
Straight into generation
Carry the planned shots into the clip in the same workspace.
How it works
Four steps, no timeline to learn.
Start from the script
Beats first. A storyboard without beats is just a list of images.
Assign framing and motion
Give every shot a shot size and a movement. Wide, medium or close, and what moves.
Lock the constants
Decide what must not change between shots — subject, outfit, lighting — and write it into every prompt.
Generate in order
Render the sequence as planned and check continuity between adjacent shots, not just within each.
What people make with it
The jobs this actually gets used for.
Ad sequences
A short sequence planned per shot so the edit is decided before rendering.
Explainer video
One shot per point, in an order that carries the argument.
Product films
A planned set of angles rather than a pile of similar clips.
Client approval
A shot list that can be agreed before anything is rendered.
Why planning saves more credits than any setting
Cheap renders are exactly why unplanned projects get expensive.
When a generation costs 5 credits, it feels free, so the natural behaviour is to iterate without a plan. Twenty unplanned attempts cost 100 credits and often produce nothing usable, because each one was answering a question that had not been asked yet.
A shot list inverts that. Every render has a defined job and a slot in the sequence, so failures are identifiable and retryable instead of just discarded.
It also fixes continuity, which is the failure people notice most in multi-shot AI video: the subject changes between cuts. Deciding the constants up front and repeating them in every prompt is unglamorous and it is most of the work.
Credits and plans
Generation is metered in credits, shared across every tool.
A five-second video costs 5 credits and one image costs 2. The Free plan gives you 30 credits every month with no credit card, no watermark and commercial use included. Paid plans start at $9 for 400 credits and add faster generation, parallel tasks and higher export resolution.

Frequently asked questions
Do I need a script first?
It helps considerably. Beats give the storyboard a structure; a list of images without beats produces a sequence that does not argue anything.
What does a shot entry contain?
Shot size, what moves, and roughly how long. That is enough to make each generation a defined job.
Does it actually reduce cost?
Yes, indirectly. The saving comes from fewer discarded renders rather than cheaper ones — unplanned iteration is the main way credit goes on multi-shot projects.
How do I keep a subject consistent across shots?
Decide the constants up front — subject, outfit, lighting, camera — and repeat the same description in every prompt. Changing one detail at a time is the only reliable method.
How much does it cost?
Storyboarding draws from the same credit balance as generation. The Free plan gives 30 credits per month with no credit card.
Can I use it for client approval?
Yes. A shot list is a good approval artefact precisely because it can be agreed before any rendering happens.
Does it work with explainer video?
Yes — one shot per point in an order that carries the argument is the clearest use of a storyboard.
Can I generate straight from the board?
Yes. Planned shots carry into generation in the same workspace rather than being retyped elsewhere.
