How to Plan and Evaluate a Multi-Scene AI Video Workflow
Searches for “Sora 2 storyboard” lead to several different products and techniques: third-party timeline forms, multi-shot prompts, and image-conditioned video workflows. They are related, but they are not interchangeable.
None of the supplied evidence establishes “Sora 2 Storyboard” as the official name of an OpenAI feature. The clearest documented examples are commercial services using that phrase for their own interfaces. These tools may still be useful for short UGC ads, product demonstrations, social videos, and pre-visualization, but their controls, prices, limits, and policies must be assessed provider by provider.
Review methodology: This comparison records controls and claims displayed on vendor pages reviewed on August 19, 2026. It is not based on independent render tests, billing tests, downloaded-file inspection, or official OpenAI documentation. Prices and plan conditions can change, so verify them again before purchasing credits.
The practical lesson is straightforward: plan the sequence before generating it, distinguish interface controls from marketing claims, and confirm material billing, privacy, rights, and failure terms before uploading client assets.
What “Sora 2 Storyboard” means—and what remains unverified
NanoPhoto.AI, SoraVideo, and Veemo use “Sora 2 Storyboard” or similar wording for third-party interfaces built around ordered scenes, separate descriptions, and duration controls. The reviewed pages do not establish that these services are authorized, endorsed, operated by, or technically integrated with OpenAI.
A provider can place “Sora 2” in a page title, show an OpenAI logo, or say that its interface submits to Sora without documenting the underlying commercial or technical relationship. Treat those elements as vendor presentation unless the provider supplies verifiable documentation.
What can be assessed more confidently is what each interface displays:
- NanoPhoto.AI shows scene cards, separate durations, add and remove controls, a total-duration counter, generation controls, and a download option.
- SoraVideo shows a linear shot form, decimal duration fields, total-runtime choices, aspect-ratio controls, an image input, task status, and download handling.
- Veemo displays multiple prompt blocks, scene durations, ratio choices, optional references, and total-runtime options.
These are features of the vendors’ own services. They should not automatically be interpreted as native or universal Sora capabilities.
The same qualification applies to technical limits. A vendor displaying a 25-second option establishes only that its interface advertises or accepts that selection. It does not establish a universal maximum across every model, account, plan, region, or integration.
This guide therefore follows four rules:
- Interface controls are attributed to the service displaying them.
- Quality, generation speed, continuity, and performance statements remain vendor claims unless independently established.
- Provider-specific prices and limits are not presented as OpenAI prices or limits.
- Billing, rights, privacy, failure treatment, and technical relationships remain unresolved where the reviewed material does not answer them.
Three different workflows hiding behind the storyboard label
A storyboard can describe a production method without identifying a specific software feature. At least three workflows sit behind the term in this market.
Timeline-style scene forms
A timeline-style workflow provides an ordered form containing multiple scene cards. Each card commonly includes:
- A scene number
- A text description
- A duration
- Add or remove controls
- A running total
- Submission controls
The interface may also offer a total-runtime selector, aspect ratio, reference upload, progress status, and download function.
The main advantage is visible duration accounting. A creator can see whether the opening consumes too much of a short ad, whether the demonstration has enough time, and whether the closing message has been squeezed into an unreadable final moment.
The limitation is that a neat interface can create a false sense of technical certainty. Scene cards do not prove that a service will produce precise cuts, stable subjects, exact prompt adherence, or independently editable scenes. Unless the provider documents otherwise, treat the cards as instructions for a generation task—not as tracks in a conventional nonlinear editor.
Prompt-only multi-shot planning
A prompt-only workflow places several planned shots inside one text request. Instead of adding cards, the writer labels and separates the instructions:
Shot 1 — Establishing shot:
Subject, action, setting, camera position, movement, lighting, and mood.
Shot 2 — Demonstration:
Subject, action, setting, camera position, movement, lighting, and mood.
Shot 3 — Result:
Subject, action, setting, camera position, movement, lighting, and mood.
Scenario recommends explicit shot blocks containing a subject, action, camera setup, lighting, and mood. Its guide also says short prompts leave more room for variation, while longer prompts express more intended constraints; neither format guarantees compliance with every detail on the Scenario Sora 2 guide.
This method provides storyboard structure without proving that a dedicated storyboard editor exists. It is useful when an interface has only one prompt field or when a creator wants a portable shot plan that can be adapted for different services.
The tradeoff is less visible timing. Durations must be written into the prompt or calculated separately, and diagnosing a failure can be difficult when several shots, movements, transitions, and continuity rules share one text box.
First-frame conditioning
First-frame conditioning begins with an image rather than a timeline. The user supplies a storyboard frame, concept image, product photograph, or other reference to guide the opening composition or general visual direction.
A reference can communicate:
- Character appearance
- Product shape and color
- Composition
- Location design
- Wardrobe
- Palette
- The intended opening shot
It does not, by itself, document a dedicated timeline, multiple editable scene cards, or scene-specific timing controls. An image may guide the beginning of a clip while leaving later motion and scene development less explicitly structured.
Reference behavior is also platform-specific. Do not assume every service supports both global references and different references for individual scenes. That capability should be described only where a provider documents it.
Choose the workflow according to the control you need:
- Use a timeline form when ordered scene entry and duration allocation are priorities.
- Use labeled shot blocks when the interface has one prompt field or portability matters.
- Use a first-frame image when the opening composition or appearance needs visual guidance.
- Combine methods only where the selected service explicitly supports the combination.
Comparison of NanoPhoto.AI, SoraVideo, and Veemo
The following table records vendor-displayed controls and claims as reviewed on August 19, 2026. It is not a comparison of official OpenAI plans, and the displayed commercial terms may change.
| Provider | Total runtime choices | Scene timing controls | Aspect ratio | Reference-image details | Advertised resolution | Displayed price | Render handling | Unresolved issues |
|---|---|---|---|---|---|---|---|---|
| NanoPhoto.AI | Up to 25 seconds total | Separate descriptions and durations; add and remove scene controls | Not established by the reviewed text | Optional references; HEIC and AVIF are among the formats mentioned | Vendor advertises 720p; not independently verified | 50 credits per storyboard video | Vendor estimates 10–20 minutes and displays generation and download controls | No numerical scene maximum; affiliation, delivered specifications, failure treatment, privacy, and reference handling remain unclear |
| SoraVideo | 10, 15, or 25 seconds | Decimal scene durations; the scenes must total the selected runtime | Landscape or portrait | JPG, PNG, or WebP device uploads up to 10 MB; public image URL offered as an alternative | Not established by the reviewed material | Runtime table: 150 credits for 10 seconds and 270 for 15 or 25 seconds; separate notice says every submission deducts 270 credits | Credits reportedly deducted when the task is created; status tracking and download shown | Material pricing contradiction; no numerical scene maximum or documented failure/refund treatment; “API” page lacks developer documentation |
| Veemo | 10, 15, or 25 seconds; 25 seconds described as a Pro option | Multiple ordered prompts with durations; vendor states a 15-second maximum per segment | Landscape or portrait | Optional references; provider describes global and per-scene use | Not established by the reviewed material | Advertised from 14 credits per second | Not sufficiently documented in the reviewed text | No numerical scene maximum; resolution, render time, privacy, failure treatment, and detailed output specifications are not documented |
NanoPhoto.AI’s 720p statement and 10–20-minute estimate are unverified vendor claims, not guaranteed delivery specifications. Its page also does not provide a complete reference-format list or a numerical maximum number of scenes.
SoraVideo presents the clearest timing-validation rule but the most important pricing conflict. Its runtime table and submission notice do not agree on the cost of a 10-second task. A buyer therefore cannot safely infer whether that submission will consume 150 or 270 credits. Resolve the discrepancy in writing before purchasing or submitting.
The SoraVideo page also uses “API” in its title, but the reviewed material presents a visual submission workflow rather than implementation documentation. It supplies no endpoints, authentication instructions, request or response schemas, error codes, rate limits, webhook details, or SDK guidance. The label alone does not establish an integration-ready developer API.
Veemo’s 25-second total and 15-second per-segment statements can coexist if a longer video contains multiple shorter segments. The exact implementation and applicable Pro plan conditions should nevertheless be confirmed with the provider.
Runtime descriptions also vary across platforms. The three storyboard vendors display options reaching 25 seconds, whereas Scenario separately describes 4-, 8-, and 12-second clips in its own workflow. Those are platform-specific descriptions, not evidence of one universal Sora runtime limit.
No reviewed source supplies a numerical maximum number of scenes. “Add scenes” or “as many as needed” should not be converted into a claim of unlimited capacity; interface, plan, complexity, or undocumented backend limits may still apply.
From creative brief to storyboard: a practical production workflow
A useful storyboard begins before the first visual prompt. Decide what the viewer must understand, in what order, and within what runtime.
1. Write a short creative summary
Use three to five lines to define:
- Audience: Who should recognize themselves or their problem?
- Message: What is the single point they should remember?
- Desired action: What should they do after watching?
- Visual tone: UGC, commercial, documentary, playful, premium, or another direction?
- Emotional progression: Curiosity to confidence, frustration to relief, doubt to proof, or another arc?
For example:
Busy home workers who dislike complicated coffee equipment. Show a compact brewer fitting naturally into a morning routine. Keep the style warm, casual, and credible rather than glossy. Move from rushed frustration to a calm result. End with the product and one readable action.
The summary is a filter. Remove scenes that do not support the message, progression, or desired action.
2. Convert the message into story beats
Reduce the concept to functional beats before writing camera prompts.
A short advertisement might use:
- Problem
- Discovery
- Demonstration
- Result
- Closing frame
A testimonial-style UGC video might use:
- Hook
- Personal problem
- Product introduction
- Demonstration
- Reaction or proof
- Call to action
The beat list defines what must happen. The shot list determines how the viewer sees it.
3. Build a production shot list
Use a worksheet with these fields:
| Field | Planning question |
|---|---|
| Scene number | Where does the shot appear in the sequence? |
| Objective | What must the viewer learn or feel? |
| Duration | How much screen time does the beat receive? |
| Subject | Who or what is the visual focus? |
| Action | What is the primary action? |
| Location | Where does it happen? |
| Framing | Wide, medium, close-up, insert, overhead, or POV? |
| Camera movement | Locked, pan, tilt, track, dolly, zoom, or another defined move? |
| Lighting | What direction, softness, temperature, and practical sources are needed? |
| Mood | Calm, urgent, playful, intimate, clinical, or premium? |
| Continuity anchors | Which character, wardrobe, prop, location, and palette details must repeat? |
| Transition | Cut, match action, reveal, connective movement, or another planned change? |
| Audio note | Dialogue, ambience, effect, music intention, or “add in edit”? |
| Reference asset | Which approved character, product, location, or composition image applies? |
One primary action and one camera setup per shot is a sound working default. A short prompt containing a dialogue exchange, crowd reaction, chase, location change, product transformation, and logo reveal creates competing priorities.
4. Choose runtime and orientation
Select the total runtime before allocating scene durations. Then decide where the finished video will appear.
Portrait framing may suit vertical social placement, while landscape may suit a website or conventional video placement. Choosing late can undermine composition: a wide group arrangement may not survive a portrait crop, and a vertical close-up sequence may leave awkward space in landscape.
Do not infer that landscape and portrait are the only ratios available everywhere. They are simply the choices displayed by two of the compared services.
5. Allocate time according to comprehension
Give the central action enough time to be understood. A product demonstration may require more time than the initial problem; a reaction-led clip may need a fast hook followed by a longer explanation or proof section.
Read the storyboard aloud or act it out with a timer. This exposes instructions that are impossible within the allocated time, such as asking someone to enter a room, locate a product, open it, use it, react, and display a readable label in three seconds.
6. Check references before uploading
Prepare reference assets only after selecting a provider. Confirm:
- Accepted formats
- Maximum file size
- Whether a public image URL is permitted or required
- Whether a reference applies globally or to one scene
- Whether the material is permitted under the provider’s current terms
- How uploads are retained, shared, reused, or deleted
As a due-diligence practice, do not upload faces, confidential products, copyrighted campaign materials, or client assets until the relevant permissions and provider terms have been reviewed.
7. Validate and submit
Before submission:
- Enter every scene duration.
- Compare their sum with the selected total.
- Confirm that each scene has one clear objective.
- Check that repeated continuity wording is unchanged.
- Verify orientation and reference settings.
- Record the displayed credit charge.
- Save the prompt and, where practical, a screenshot of the settings.
Submit only after the storyboard satisfies the interface’s timing requirements. Monitor progress where supported, download the result, and review it outside the generation interface on the type of screen the audience will use.
8. Treat the first output as a draft
Review the result for:
- Narrative clarity
- Readable shot duration
- Face, wardrobe, product, and background continuity
- Unwanted camera or subject motion
- Intelligible transitions
- Final-message readability
- Correct crop and orientation
- Accurate brand details
For a longer or more complicated narrative, consider generating focused shots separately and assembling them in a conventional editor. That provides direct control over shot order, trims, audio, titles, replacement takes, and precise final typography. Structured pre-production, essential-action framing, and manual continuity review are also recommended in broader AI storyboarding guidance.
Timing worksheets for 10-, 15-, and 25-second storyboards
SoraVideo’s documented rule is that decimal scene durations may be entered and all scenes must add up to the selected runtime, as summarized in the provider comparison above. Whether another service enforces the same validation should be checked in its own form.
Use this formula:
Scene 1 duration + Scene 2 duration + … + final scene duration
= selected total runtime
If the two sides are not equal, revise the allocation before submission.
10-second, three-shot structure
| Scene | Purpose | Duration |
|---|---|---|
| 1 | Opening context or problem | 3 seconds |
| 2 | Central action or demonstration | 4 seconds |
| 3 | Outcome or closing frame | 3 seconds |
| Total | 10 seconds |
This structure suits one simple proposition. The middle shot receives the largest share because it carries the central action.
15-second advertisement structure
| Scene | Purpose | Duration |
|---|---|---|
| 1 | Problem | 4 seconds |
| 2 | Product demonstration | 7 seconds |
| 3 | Result and call to action | 4 seconds |
| Total | 15 seconds |
The longer middle section gives a demonstration room to show a sequence rather than one unexplained product image.
25-second, five-shot brand structure
| Scene | Purpose | Duration |
|---|---|---|
| 1 | Setup | 5 seconds |
| 2 | Discovery | 5 seconds |
| 3 | Action | 5 seconds |
| 4 | Result | 5 seconds |
| 5 | Brand close | 5 seconds |
| Total | 25 seconds |
Equal lengths are easy to validate, but they are not automatically the best creative choice. Reallocate time when one beat requires more explanation.
Alternative 25-second UGC structure
| Scene | Purpose | Duration |
|---|---|---|
| 1 | Hook | 3 seconds |
| 2 | Personal problem | 5 seconds |
| 3 | Demonstration | 8 seconds |
| 4 | Reaction or proof | 5 seconds |
| 5 | Closing action | 4 seconds |
| Total | 25 seconds |
This version prioritizes the demonstration while retaining a fast opening.
Do not maximize scene count merely because an interface has an “add scene” button. No reviewed source establishes a numerical maximum or proves that very short scene cards produce smoother cuts. More scenes mean less time for each action, more continuity boundaries, and more opportunities for unclear transitions.
Likewise, vendor advice about 1–2-second cards or particular card spacing should be treated as workflow guidance, not a performance guarantee. Budget for comprehensible action. If a transition is unclear, simplify the change or add a connective shot.
A reusable Sora 2 storyboard prompt template
Use this structure for each scene:
Scene objective; subject and action; environment; shot size and camera position; lens or visual perspective where useful; camera movement; lighting and palette; mood; continuity anchors; transition; audio note where supported.
Each field has a distinct role:
- Scene objective: Explains why the shot exists.
- Subject and action: Identifies the visual focus and one primary event.
- Environment: Establishes location, time, weather, surfaces, and relevant background details.
- Shot size and camera position: Defines what is visible and from where.
- Lens or perspective: Communicates spatial character, such as wide, intimate, natural, or compressed.
- Camera movement: Distinguishes a locked frame from a deliberate pan, tilt, track, dolly, or zoom.
- Lighting and palette: Sets direction, softness, temperature, contrast, and recurring colors.
- Mood: Connects visual choices to the intended emotion.
- Continuity anchors: Repeats details that should persist across scenes.
- Transition: Describes how the next beat should connect.
- Audio note: Records dialogue, ambience, effects, or post-production needs where supported.
For prompt-only workflows, label sections explicitly as “Shot 1,” “Shot 2,” and “Shot 3.” Clear labels make sequence, timing, and revision easier to inspect.
Three-shot product example
Shot 1 — 3 seconds — Problem
Objective: Establish a rushed morning.
Subject and action: Same creator searches a cluttered counter for coffee supplies.
Environment: Small apartment kitchen at sunrise.
Framing: Medium-wide shot from counter height.
Camera movement: Slow lateral track.
Lighting and palette: Warm window light from camera left; cream, muted teal,
and walnut palette.
Mood: Busy but believable.
Continuity: Apply the master continuity block.
Transition: Cut on the creator turning toward the product.
Audio note: Kitchen ambience; add voice-over in edit.
Shot 2 — 4 seconds — Demonstration
Objective: Show the product’s central use clearly.
Subject and action: Same creator places the compact brewer over a ceramic mug
and presses one button.
Environment: Same kitchen and counter.
Framing: Close product insert from a three-quarter angle.
Camera movement: Locked camera.
Lighting and palette: Same warm light direction and palette.
Mood: Simple and controlled.
Continuity: Apply the master continuity block.
Transition: Match cut from the illuminated button to the filled mug.
Audio note: Button click and subtle brewing sound if supported.
Shot 3 — 3 seconds — Result
Objective: Communicate relief and present the product.
Subject and action: Same creator takes one sip, smiles naturally, and places
the brewer beside the mug.
Environment: Same kitchen.
Framing: Medium close-up with product visible in the foreground.
Camera movement: Gentle push-in.
Lighting and palette: Same warm light and palette.
Mood: Calm and satisfied.
Continuity: Apply the master continuity block.
Transition: Hold on a clean closing composition.
Audio note: Add final voice-over and on-screen call to action in edit.
Master continuity block
Copy the same block without alteration into every relevant scene:
CONTINUITY: Same adult creator with oval face, shoulder-length dark brown hair,
navy overshirt, white T-shirt, and silver watch. Same matte cream compact brewer
with a teal circular button and label centered on the front. Same small kitchen
with walnut counter, cream tile, and one plant beside the window. Muted teal,
cream, and warm brown palette. Soft morning light always enters from camera left.
Adapt the details to the project, but retain the method: define character appearance, wardrobe, signature accessory, product appearance, location, palette, and lighting direction.
Repeated wording reduces accidental contradictions in the written plan. It does not guarantee that generated subjects or objects will remain identical.
Rewrite an overloaded prompt
Overloaded version:
A creator talks to a crowd in a city square, gets chased through traffic while explaining the product, enters a luxury apartment, opens the package, demonstrates it, and reveals the logo as fireworks appear, with dialogue and several camera moves.
This combines a crowd, dialogue, a chase, a location change, a demonstration, a product reveal, effects, and several implied camera setups.
Focused rewrite:
Shot 1 — Hook
Medium shot of the creator addressing the camera at the quiet edge of a city
square. One sentence of direct-to-camera dialogue. Locked camera. Bright
overcast light.
Shot 2 — Urgency
Side tracking shot of the same creator walking quickly along the pavement while
holding the unopened product package. No crowd interaction and no dialogue.
Shot 3 — Product reveal
Close overhead shot in the apartment. The same hands open the package and place
the product in the center of the table. Locked camera and soft window light.
Shot 4 — Demonstration
Three-quarter close-up of one product function. One action only. Slow push-in.
Shot 5 — Brand close
Clean product composition with the creator in the background. Hold the final
frame for the call to action; add typography and fireworks-style graphics in edit.
Short prompts leave more choices unspecified. Longer prompts can express more intended constraints, but excessive detail can become internally contradictory. Neither approach guarantees exact adherence.
Treat audio as a planning field, not an assumed scene-level control. The compared storyboard interfaces do not provide enough evidence to promise reliable per-scene dialogue, effects, music, or synchronization. Record what each shot needs, then confirm whether the selected workflow supports it or finish audio in editing.
Continuity and pacing problems: a troubleshooting matrix
Storyboard planning cannot guarantee continuity, but it can make errors easier to diagnose.
| Symptom | Likely planning causes | Bounded corrective action |
|---|---|---|
| Character appearance drifts | Identity wording changes; wardrobe omitted; conflicting references; too many subjects | Repeat identical identity, hairstyle, wardrobe, and accessory wording. Use an approved reference where supported. Compare alternative takes manually. |
| Product or prop changes | Color, material, shape, label, or placement is underspecified | Repeat product color, shape, material, label position, relevant dimensions, and placement. Check every shot against an approved product image. |
| Environment changes | Location wording varies; persistent details are omitted; location changes abruptly | Reuse the same location description. Name persistent surfaces, furniture, weather, and background objects. Give genuine location changes dedicated shots. |
| Lighting becomes inconsistent | Time of day, direction, softness, temperature, or palette changes | Repeat time of day, light direction, softness, color temperature, contrast, and palette. Remove conflicting style language. |
| Cut feels abrupt | Too much changes at once; there is no connective action; transition is underspecified | Add a connective beat, use match action, or simplify the change. Do not assume a particular card length will fix it. |
| Scene feels crowded | Several actions, subjects, locations, effects, or camera moves compete | Split the scene into focused shots. Generate separately and assemble in editing if necessary. |
| Pacing feels weak | The scene lacks a clear purpose; setup runs long; the central action is rushed | Restate each scene’s objective and reallocate time. Remove redundant beats instead of adding more descriptive language. |
| Framing is wrong | Shot size, viewpoint, camera height, or movement is omitted | Specify shot size, point of view, camera position, and either a locked camera or one defined movement. |
| Closing message is unreadable | Final composition is busy or receives too little time | Simplify the background, reserve a stable hold, and add final typography in editing where precise text matters. |
| Continuity fails across the sequence | Too much complexity is requested in one generation | Generate shorter, focused takes and rebuild the sequence in an editor with direct control over order and trims. |
Third-party troubleshooting guidance similarly recommends standardized descriptions, deliberate lighting and camera instructions, simpler shots, multiple takes, and editing complex sequences from separate clips. These are practical recommendations rather than measured guarantees in the Studio Prompt troubleshooting guide.
After generation, inspect:
- Faces, hair, bodies, and hands
- Wardrobe and accessories
- Product shape, labels, and colors
- Prop locations
- Background architecture and furniture
- Palette and exposure
- Light direction and softness
- Logos and other brand details
- Orientation and crop
- Final-frame readability
Generate multiple takes when the budget permits, but define acceptance criteria first. Additional takes are not useful if the reviewer has not decided which product details, performances, and continuity elements are essential.
These practices may improve production discipline and make revisions easier to communicate. They do not establish guaranteed continuity, seamless transitions, exact prompt adherence, synchronized audio, or error-free branded output.
What to verify before spending credits or uploading a reference
A polished interface is not a substitute for clear commercial, privacy, and technical terms. Use this checklist before testing a third-party storyboard service with client work.
Provider identity and claimed relationship
Ask:
- Who operates the service?
- Does it claim a relationship with OpenAI?
- Where is that relationship documented?
- Can the statement be verified outside promotional copy?
- Which company handles billing, support, moderation, and data processing?
Do not infer authorization from branding, logos, or model names.
Credits, charges, and failures
Confirm in writing:
- The current credit charge for each runtime
- Whether the price is promotional or plan-dependent
- Whether a subscription is also required
- When credits are deducted
- What happens after failure, timeout, rejection, or moderation
- Whether retries consume additional credits
- Whether unused credits expire
- Whether partial or unusable results qualify for any remedy
Also ask whether one scene can be regenerated independently. Editing one card before another submission does not necessarily mean the provider can rerender only that segment. If the complete storyboard must be regenerated, a small revision may incur the full charge.
Delivered video specifications
Verify the actual delivered file rather than relying only on promotional wording:
- Pixel dimensions
- Frame rate
- Codec and container
- Bit rate where relevant
- Landscape or portrait dimensions
- Audio tracks
- Watermark policy
- Download availability and expiry
- Expected render range
- Whether queue delays affect that estimate
If possible, run a non-sensitive test and inspect the downloaded file metadata.
Ownership and permitted use
Review the provider’s current terms for:
- Ownership of prompts, uploads, and outputs
- Commercial use of generated footage
- Restrictions on advertising or client work
- Treatment of copyrighted reference assets
- Brand and product materials
- Likeness and identity permissions
- Voice or dialogue permissions
- Provider licenses over uploaded and generated material
- Watermarks or attribution requirements
A generation button does not by itself establish unrestricted commercial rights. Treat permissions for faces, products, trademarks, campaign materials, and other supplied assets as a due-diligence issue to resolve before submission.
Privacy, retention, and training
Before uploading a face, unreleased product, campaign brief, or client image, determine:
- Where files are processed and stored
- How long prompts, references, and outputs are retained
- Whether deletion can be requested
- Whether material may be used for training
- Whether files are shared with subprocessors
- Whether public URLs expose reference images
- How accounts and generated files are secured
- What happens to stored data after account closure
Do not assume uploads are private, deleted after processing, or excluded from training unless the current terms say so.
Moderation and prohibited content
Check rules that may affect:
- Real-person likenesses
- Minors
- Political content
- Health or financial claims
- Regulated products
- Violence or sexual content
- Copyrighted characters
- Celebrity impersonation
- Deceptive advertising
Reviewing these rules before submission reduces the risk of discovering only after a charge that the request cannot be processed.
API verification
If a service is marketed as an API, require documentation covering:
- Base URL and endpoints
- Authentication
- Request and response schemas
- Upload handling
- Status polling or webhooks
- Errors
- Rate limits
- Retry and idempotency behavior
- Billing events
- Moderation responses
- Retention and deletion
- Versioning and support
Until those materials are available, treat an interface like SoraVideo’s as a web submission tool rather than an integration-ready developer product.
The decision rule is simple: choose a provider only after it answers the material billing, rights, privacy, moderation, delivered-format, and failure-handling questions in writing.
Frequently asked questions
Is Sora 2 Storyboard an official OpenAI feature?
The reviewed evidence does not establish “Sora 2 Storyboard” as the official name of an OpenAI feature. The clearest documented examples are third-party commercial interfaces from NanoPhoto.AI, SoraVideo, and Veemo.
Their product pages also do not establish that the providers are authorized, endorsed, or operated by OpenAI. Treat the phrase as a market label unless a provider supplies verifiable documentation confirming otherwise.
How many scenes can a Sora 2 storyboard contain?
No reviewed source provides a numerical maximum. The interfaces show multiple scenes and add-scene controls, but that does not prove unlimited capacity.
Ask the provider about interface limits, plan limits, minimum scene duration, and practical generation constraints. Regardless of the technical maximum, use only as many scenes as the viewer can understand within the selected runtime.
What happens if the scene durations do not equal the selected runtime?
SoraVideo says its scene durations must total the selected runtime and that decimal durations may be entered. The reviewed material does not document the exact error message or submission behavior when they do not match.
Calculate the total before submitting:
Sum of all scene durations = selected runtime
If the values differ, reallocate time rather than assuming the service will correct them automatically.
Does the SoraVideo Storyboard page document a usable developer API?
No. Although the page uses API language, the reviewed material does not include endpoints, authentication instructions, schemas, rate limits, error handling, or the other details needed to implement an integration.
It documents a visual workflow for creating, tracking, and downloading storyboard tasks. Request full developer documentation before treating it as a usable API.
Which reference-image formats do the compared storyboard tools accept?
NanoPhoto.AI mentions HEIC and AVIF among its supported formats but does not provide a complete list in the reviewed text.
SoraVideo specifies JPG, PNG, and WebP device uploads up to 10 MB and offers a publicly reachable image URL as an alternative.
Veemo describes optional global and per-scene references, but the reviewed material does not establish its accepted file formats or file-size limit.
Check the current upload form and privacy terms before preparing a reference. Format support, size limits, retention, and reference behavior are provider-specific and may change.
Conclusion
A useful Sora 2 storyboard begins with disciplined shot planning, explicit timing, repeatable continuity details, and manual review—not confidence in a vendor label.
Third-party tools can provide convenient scene cards, reference uploads, runtime controls, render tracking, and downloads. Their specifications and prices are nevertheless provider-specific, and the reviewed pages leave important questions unanswered or, in SoraVideo’s case, present contradictory pricing information.
Before committing real client work, confirm the provider’s current charges, failed-render treatment, privacy and retention rules, commercial-use terms, moderation policies, delivered file specifications, and any claimed OpenAI relationship. Start with a low-risk test rather than a confidential campaign, an unreleased product, or an irreplaceable reference asset.
