Best-fit tasks
- Turn a complete shot brief into a generated video sequence.
- Animate a supplied image while preserving its subject and visual direction.
- Generate an audio-capable result on supported video routes.
- Control a transition by defining both the opening and closing composition.
Prompt starters
Replace the bracketsStarter
Create one [duration]-second shot of [subject] in [setting]. The subject [action]. Camera: [movement and framing]. Lighting: [direction and mood]. Keep motion physically coherent and the shot continuous.
Starter
Animate the supplied image into a [duration]-second shot. Preserve [subject details]. Add [subject motion] and [camera motion]. Keep the original composition, lighting, and visual identity stable.
Starter
Start exactly from the first frame and end on the supplied last frame. Build one continuous transition where [subject or camera action] connects both compositions without cuts.

FAQ
MiniMax H3 Eco API questions
What model ID should I use for the MiniMax H3 Eco API?+
Use minimax-h3-eco in the model field. This is the stable PixMind route identifier shown in the playground request JSON.
Which endpoint does the MiniMax H3 Eco API use?+
Send POST requests to /v1/generations. Keep your API key on your server and pass it as a Bearer token.
Is the playground using a real API request?+
Yes. When you click Run model, PixMind forwards the displayed payload with the API key you entered. A successful request may create a paid task.
Does PixMind save the API key entered here?+
No. The playground keeps the key only in component memory and sends it for the current request; it is not written to browser storage.
Is API pricing the same as PixMind Studio pricing?+
No. API usage resolves through the apiPlatform pricing role and a separate pay-as-you-go ledger. Studio pricing includes the creation interface and product workflow services.
Why can the final price differ from the starting price?+
The entry price reflects the configuration displayed on this page. Resolution, duration, quality, audio, references, and output count can affect the final task price.
How do I receive a finished image or video?+
Generation routes can return an asynchronous task. Save its ID and query the task endpoint until the status is succeeded, failed, or cancelled.
Can I use the same integration for other PixMind models?+
Yes. Models in the same workload family share the generation contract, so switching usually means changing the model ID and supported parameters.
