MiniMax H3, Seedance and Wan are Chinese video-model routes to investigate when replacing a Sora workflow. Choose between them by the production brief and available access path: references, clip duration, audio, editing and delivery all affect the integration. A model showcase is not a complete replacement workflow.
OpenAI's Sora discontinuation notice gives April 26, 2026 for the web and app shutdown and September 24, 2026 for the planned API shutdown. Those are official dates, not the result of a request probe in this article. This documentation review is dated October 2, 2026; no paired video-generation comparison was run.
List the inputs attached to one completed project: prompt, source image, reference clips, sound, aspect ratio and editing instructions. Then list the outputs your application used: rendered video, audio track, preview image, duration and project metadata. Separate model output from features supplied by the original app.
A website that displays a finished MP4 needs less integration work than a studio that stores reusable characters and edit history. Provider-specific project objects rarely transfer through a prompt. Export the source materials and record the intended result in an application-owned brief before choosing a new endpoint.
For a first pilot, use a short product clip with an owned reference image. Specify one camera movement, a fixed aspect ratio, an intended duration and whether sound is required. That creates a manageable comparison and exposes reference handling without requiring an entire campaign to be rebuilt.
Start from the MiniMax H3 model page, Seedance 2.5 page and video capability directory. Follow the official access links for the exact model and your region. Keep direct provider access distinct from a third-party marketplace serving a similarly named model.
The Seedance product page describes the model's creative capabilities. That alone does not establish that your account can submit the corresponding API job. Check current API documentation and console availability before building against it. Apply the same check to an exact Wan version and its hosting provider.
| Migration requirement | Evidence to collect |
|---|---|
| Image or video reference input | Accepted format, size, count and request fields |
| Generated or attached audio | Documented audio behavior for the selected model |
| Finished video delivery | Output URL lifetime and download behavior |
| Production availability | Model ID, region and account access |
Avoid selecting a route only because its brand appears in an alternatives list. A direct API and an app subscription may expose different model versions, limits and editing features.
Treat video generation as a job with its own stored state. Save the application job ID before submission, then attach the provider job ID once received. Track submitted, running, completed and failed states, together with any provider-specific status needed for diagnosis.
If the connection drops after submission, investigate the existing job before sending another request. A blind retry can create a second billable generation. Distinguish a submission failure from a polling failure and from a generation failure; they need different recovery behavior.
On completion, download the usable artifact into the project's intended storage before an output URL expires. Record duration, dimensions and whether the file actually contains audio. A successful job status cannot prove the delivered clip has every property your editor expects.
Use polling intervals and a total timeout that fit the documented provider contract. If webhooks are available, retain a reconciliation path for missed deliveries. The application should be able to recover the job state without asking a user to regenerate a completed clip.
Store original reference assets rather than treating a provider-uploaded reference ID as the only copy. Preserve a mapping to each provider's upload resource. Before sending a reference, validate orientation and crop so the model receives the intended composition.
Review a completed clip against the brief: object identity, continuity, requested movement, aspect ratio and sound. A visually attractive scene can still fail a product brief if a logo changes or a bottle becomes a different shape. Record those defects separately from whether the API delivered a valid file.
For repeatable evaluation, use identical source materials and clearly equivalent task instructions. Save every submitted prompt and returned clip. If you change the prompt after seeing one model's result, label that as another attempt rather than a controlled first-run comparison.
MiniMax's published video pricing distinguishes model, resolution, generation duration and reference-material charges. H3 rates include $0.08 per generated second at 768P and $0.13 at 2K. These numbers do not establish a universal total price for every referenced-video request.
Build a cost record containing generated seconds, input-material charges, any enhancement and each attempt. Divide the total job cost by the number of clips that pass the brief. A lower generation rate can still produce a higher cost per usable clip if it needs more regeneration.
Compare audio and delivery work too. If the selected route does not supply the required soundtrack, include the separate speech, music or editing step in the workflow estimate. This guide offers a migration plan, not a claim that every listed model reproduces Sora's features. Use the H3 prompt guide when refining that specific route.
MiniMax H3, Seedance and Wan are candidates, but the answer depends on the exact workflow and current access. Verify references, output audio, duration and account availability for the intended version.
Original assets can be reused where the new provider accepts them. Provider-specific project and character IDs require a new mapping or reconstruction; do not assume they are portable.
No shared audio contract is established by the category name. Check the selected model and request mode, then inspect the delivered file before treating audio as complete.
