Input: one idea and four intended beats
Output: four connected shots with a consistent style
Aspect: 9:16 or 16:9 across the board
Build log
1. Write four beats
Setup, action, reaction, result. If a beat has no visible change, it is not a shot.
2. Build Canvas nodes
Each node gets reference, prompt, duration, and purpose. Reviewers can see the chain before generation.
3. Generate cheap probes
I use 5-second Agnes shots at 10 credits each. This tests continuity without spending 360 credits on a paid set.
4. Fix continuity first
Style, light, and camera distance are checked before render upgrades. A good paid render cannot fix a broken chain.
Complete execution record
Task boundary and source gate
Treat AI storyboard video generator as a deliverable, not a definition. The job receives one idea and four intended beats and owes four connected shots with a consistent style in 9:16 or 16:9 across the board. Write the rejection reason first, then turn it into the first hard constraint.
Require a character sheet, prop state, location notes, color grade, time of day, sound intention, and shot order. Do not let a strong style erase story time, character state, or the audience's understanding of who did what.
The imgmov route
Treat Canvas as the continuity ledger. Each node stores reference, prompt, camera, duration, and dependency. Generate the missing bridge only after stills and story beats are approved.
Keep platform requirements outside the model prompt. The prompt can describe a scene; a named checklist records the crop, claim, consent, and console check that make it deliverable.
Lock the variables that cannot drift
Lock face, costume, props, grade, lens height, location, story time, and dialogue line. Continuity beats novelty.
Put the locked fields at the top of the prompt, not at the end: Set setup, action, reaction, and result as four nodes. Each 5-second Agnes shot is 10 credits; four shots cost 40 credits. Upgrade the approved sequence to Seedance 480p for 360 credits or 720p for 780 credits. Save that prompt with the reference, ratio, and model so the next run starts from a decision instead of a guess.
Step-by-step build path
1) Write four beats: Setup, action, reaction, result. If a beat has no visible change, it is not a shot. Leave one checkable artifact from this step; do not start the next until it exists. 2) Build Canvas nodes: Each node gets reference, prompt, duration, and purpose. Reviewers can see the chain before generation. Leave one checkable artifact from this step; do not start the next until it exists. 3) Generate cheap probes: I use 5-second Agnes shots at 10 credits each. This tests continuity without spending 360 credits on a paid set. Leave one checkable artifact from this step; do not start the next until it exists. 4) Fix continuity first: Style, light, and camera distance are checked before render upgrades. A good paid render cannot fix a broken chain. Leave one checkable artifact from this step; do not start the next until it exists.
Change one named variable per rerun: prompt, reference, camera, duration, model, ratio, or export crop. If two variables change together, a better output cannot be reused because nobody knows which fix worked.
Review gates and evidence
A viewer should order the shots without help, recognize the same character, and see no prop teleport between frames.
Keep source, approved wording, rejected version, correction, credit cost, and final crop next to the asset. The record exists so the next reviewer can reproduce the decision without a chat thread.
Failure diagnosis and retry ladder
Repair the reference before rewriting the prompt. If a transition fails, insert a short still instead of paying for a longer guessing shot.
Do not upgrade on hope. A 5-second Agnes Video probe is 10 credits. If the concept passes, Seedance 2.5 costs 90 credits at 480p or 195 at 720p for 5 seconds; Kling is 195 without audio or 245 with audio. Veo enters only when a 4/6/8-second cinematic bucket is genuinely worth 80/125/165 credits. Prove hook, subject, and rhythm first, then pay to clean up motion that already worked.
Versioning and handoff
Hand off Canvas, reference IDs, prompt history, first/last frames, caption track, and the approved cut.
The folder is boring on purpose: source, approved reference, generation settings, caption file, platform cuts, QA screenshots, and one correction line. A reusable asset is boring in the right way.
Why this is not a generic answer
The imgmov advantage is the chain: Asset Library preserves the subject reference, Canvas fixes shot order and first/last frames, the workspace routes Agnes to Seedance, Kling, or Veo only after proof, and your external editor adds captions and CTA without regenerating the media.
Do not let a strong style erase story time, character state, or the audience's understanding of who did what. If the request only asks what ai storyboard video generator means, a search page is faster. This page is useful when someone must deliver four connected shots with a consistent style under real constraints.
Frequently asked questions
How many shots should a storyboard have?
Four is enough for a short idea. Add more only after continuity passes.
The workflow is specific about its stopping point: it starts with one idea and four intended beats and stops at four connected shots with a consistent style. In imgmov, upload the source, lock it as a reference, set 9:16 or 16:9 across the board, run one proof, and save the passing settings. If a reviewer cannot tell which version is approved, the workflow has failed even when the media looks good.
How much does a 4-shot test cost?
40 credits on Agnes Video. Four Seedance 480p shots are 360 credits; 720p is 780 credits.
Do not upgrade on hope. A 5-second Agnes Video probe is 10 credits. If the concept passes, Seedance 2.5 costs 90 credits at 480p or 195 at 720p for 5 seconds; Kling is 195 without audio or 245 with audio. Veo enters only when a 4/6/8-second cinematic bucket is genuinely worth 80/125/165 credits. Prove hook, subject, and rhythm first, then pay to clean up motion that already worked.
Should shots be long?
No. Short 5-second shots make continuity easier to control.
The check is not “does it look AI-nice?” It is: A viewer should order the shots without help, recognize the same character, and see no prop teleport between frames. Then the source, approved copy, rejected version, correction, and final crop stay in the same handoff folder.
Where do I keep references?
In Canvas nodes and the asset library, so every shot uses the same style sheet.
Repair the reference before rewriting the prompt. If a transition fails, insert a short still instead of paying for a longer guessing shot. Change one named variable, keep the old version, and record the credit cost. If the same failure repeats, fix the reference or scope rather than asking the prompt for forgiveness.
When do I switch to paid models?
Only after the four-beat chain passes.
The imgmov advantage is the chain: Asset Library preserves the subject reference, Canvas fixes shot order and first/last frames, the workspace routes Agnes to Seedance, Kling, or Veo only after proof, and your external editor adds captions and CTA without regenerating the media. The handoff is reusable only when the source, reference ID, prompt, model, cost, rejection reason, and approved cut are linked. That chain is what makes the next ai storyboard video generator task faster.
