MiniMax H3 FAQ
Is h3minimax.com an official MiniMax website?
No. It is an independent third-party service and is not affiliated with, endorsed by, or authorized by MiniMax.
Which H3 modes are available?
Text-to-video and image-to-video, using the corresponding MiniMax H3 model IDs documented by Kie.ai.
Which durations and resolutions are accepted?
The H3 launch accepts 4–15 second durations and 768P or 2K resolution. Text-to-video also exposes the documented aspect-ratio enum.
How are image frames handled?
Frames are uploaded through the existing authenticated asset flow. The API resolves the stored asset ID and refuses arbitrary browser-supplied frame URLs.
How is task progress checked?
The server stores the provider task ID and maps Kie.ai task states to queued, processing, succeeded, or failed. Browser polling asks only for the account-owned internal task ID.
What happens to credits when a task fails?
Credits are reserved before provider submission. Success settlement and failure release happen server-side with idempotency boundaries; the client cannot request a refund by changing callback data.
