MiniMax H3 Video Generation
Generate 4–15 second videos from text, up to 9 reference images, or up to 3 reference audio clips with a single REST API. Unified asynchronous tasks, callbacks, billing, and CDN delivery integrate directly into your content product.
One API, Three Creative Starting Points
No action or multiple paths required; the API automatically determines the generation mode based on the content assets.
Text-to-Video
Generate short videos directly from descriptions of scenes, actions, camera shots, and styles.
First-and-Last-Frame Image-to-Video
Control the opening and ending visuals with first_frame and last_frame.
Multimodal References
Combine reference images, videos, and audio to guide subjects, actions, sound, and rhythm.
Asynchronous Delivery
Receive a task ID immediately, then get the final CDN video through polling or callback_url.
curl -X POST 'https://api.acedata.cloud/minimax/videos' \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{

Parameters directly express creative intent, while the platform handles long-running task execution, result storage, and precise billing.
Build content
All modes must provide text; images, videos, and audio indicate their purpose through their corresponding types and roles.
Submit an Asynchronous Task
The creation API is always asynchronous and returns a task_id immediately upon success.
Get Permanent Results
Retrieve the Ace Data Cloud CDN video from task.content.url via /minimax/tasks or a callback.
Typical scenarios from source material to finished video
Three real API samples cover product activation, character storytelling, and audio-visual reference workflows.
Brand and e-commerce shorts
Create commercial shorts from product visuals and shot descriptions, ideal for product showcases, launch assets, and social media ads.
Consistent character storytelling
Use multiple proprietary reference images to improve consistency in characters, clothing, props, and scene styles, ideal for continuous shots and serialized content.
Audio-visual rhythm shorts
Combine proprietary motion video and audio references to guide dance movements, camera motion, and visual rhythm, ideal for vertical content creation.
Go live in three steps
Reuse Ace Data Cloud's unified authentication and task system without building a separate media pipeline.
Get a Token
Create an application in the console and obtain a unified Bearer Token.
Submit generation
Choose the duration and aspect ratio, then add text, image, or audio assets.
Deliver video
Poll the task or receive a callback, then integrate the CDN video into your product workflow.
Unified Video API for Production
Consolidate task execution, error semantics, usage records, and file delivery into a stable contract.
| Capability | Ace Data Cloud MiniMax H3 | Some Others |
|---|---|---|
| Multimodal input | Unified entry point for text, images, video, and audio | Multiple APIs to assemble yourself |
| Long-running tasks | Polling and Webhook | Need to build your own task queue |
| Result files | Automatically stored on the platform CDN | Inconsistent link lifecycles |
| Failure billing | No charge for failures | Need to reconcile bills yourself |
Select a workflow by content
The model is fixed as MiniMax-H3, and the mode is automatically inferred from the official V2 multimodal content array.
text
Pass text content only to generate visuals directly from ideas, scripts, and shot descriptions.
first_frame / last_frame
Use the first frame or the first and last frames to control the video's opening and ending visuals.
reference media
Combine reference images, video, and audio to control the subject, motion, sound, and rhythm.
task_id / callback
Create asynchronous tasks and retrieve results through task queries or callbacks.
Transparent resolution pricing
Billed by video seconds, with charges only for successful tasks.
768P
- As low as $0.228572 for 4 seconds
- Ideal for rapid creative validation
- Three input modes
2K
- As low as $0.365716 for 4 seconds
- Default output resolution
- Asynchronous task queries
Frequently Asked Questions
Key notes on modes, assets, duration, and task execution.
Do I need to pass action?
No. When content only has text, it is text-to-video; first_frame / last_frame are image-to-video; reference_* are multimodal reference-to-video. All modes require non-empty text.
What aspect ratios and durations are supported?
Resolution is required, with support for 768P and 2K; supported ratios include adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16; duration is an integer from 4–15 seconds.
How do I get the results?
The creation API is always asynchronous and immediately returns task_id; use /minimax/tasks to query it. Upon success, get the video from task.content.url, or provide callback_url.
Are failed tasks charged?
No. Only tasks that successfully complete and return video results are billed based on the final duration.
