One Interface, Three Creative Starting Points

No actions or multiple paths required; the interface automatically determines the generation mode based on content materials.

✍️

Text-to-Video

Directly generate short films from scene, action, shot, and style descriptions.

Frame-to-Frame Video Generation

Control the start and end frames through first_frame and last_frame.

🎵

Multi-modal References

Combine reference images, videos, and audio to guide subjects, actions, sounds, and rhythms.

📡

Asynchronous Delivery

Immediately return task ID and receive the final CDN video via polling or callback_url.

Start Generating with a Few Lines of Code

Parameters directly express creative intent, while the platform handles long task execution, result storage, and precise billing.

Construct Content

All modes must provide text; images, videos, and audio are labeled for use through corresponding types and roles.

Submit Asynchronous Task

The interface is fixed asynchronous; it immediately returns task_id upon success.

Obtain Permanent Results

Get AceDataCloud CDN video from task.content.url via `/minimax/tasks` or callback.

Common Scenarios from Material to Finished Film

The same model covers creative exploration, activation of static materials, and music rhythm short films.

Marketing Short Film

Quickly generate horizontal ads or vertical social media materials from product selling points and shot scripts.

Character Consistency

Constrain character, clothing, props, and scene style with multiple reference images.

Rhythm Visuals

Make dance, camera movement, and scene changes follow the rhythm of the reference audio.

Three Steps to Go Live

Utilize AceDataCloud's unified authentication and task system without the need to build a separate media pipeline.

Get Token

Create an application in the console and obtain a unified Bearer Token.

Submit Generation

Select duration and aspect ratio, and add text, images, or audio materials.

Deliver Video

Poll for tasks or receive callbacks to integrate CDN video into the product workflow.

Unified Video Interface for Production

Converge task execution, error semantics, usage records, and file delivery into a stable contract.

Capability	AceDataCloud MiniMax H3	Some Others
Multimodal Input	Unified entry for text, images, videos, and audio	Multiple interfaces stitched together
Long Tasks	Polling and Webhook	Requires self-built task queue
Result Files	Automatic storage on platform CDN	Inconsistent link lifecycle
Failure Billing	No charges for failures	Requires self-verification of bills

Select Workflow by Content

The model is fixed to MiniMax-H3, and the mode is automatically inferred from the official V2 multimodal content array.

TEXT

text

Only transmit text content, directly generating visuals from ideas, scripts, and shot descriptions.

FRAME

first_frame / last_frame

Use the first frame or the first and last frames to control the start and end visuals of the video.

REFERENCE

reference media

Combine reference images, videos, and audio to control subjects, actions, sounds, and rhythms.

TASK

task_id / callback

Create fixed asynchronous tasks to obtain results through task queries or callbacks.

Frequently Asked Questions

Key notes on modes, materials, duration, and task execution.

Is action required?

No. When content is only text, it is text-to-video; first_frame / last_frame is image-to-video; reference_* is multimodal reference video. All modes require non-empty text.

What ratios and durations are supported?

Resolution is required, supporting 768P and 2K; ratios support adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16; duration is an integer from 4 to 15 seconds.

How to obtain results?

Create an interface that is fixed asynchronous and immediately returns task_id; use `/minimax/tasks` to query, and on success, get the video from task.content.url, or provide callback_url.

Will failed tasks incur charges?

No. Only tasks that are successfully completed and return video results are charged based on final duration.
