How to use MiniMax H3 Max
Getting started
Choose the mode for the material you already have. Start with text for a new scene, image-to-video for an opening photo, or a video-editing mode for an existing clip. The default endpoint on this page creates video from text; the other modes have their own model IDs.
Example prompt
A cyclist rides along a quiet riverside path in warm morning light. The camera follows from the side at a steady distance. Keep the rider and bicycle consistent in one continuous shot.
Review your result
Watch the whole clip and listen to the soundtrack. Check the bicycle wheels, body movement, background continuity and any requested speech. Keep the original input and selected settings when comparing another mode.
Inputs and settings
Describe the subject, one main action and camera movement in prompt. Choose duration, resolution and aspect_ratio from the current schema before requesting a quote.
prompt_expansion_mode controls whether the prompt is rewritten. When comparing your own instructions, keep the same expansion setting and record any expanded prompt returned with the result.
An optional target_audio_url can supply a soundtrack. Review the supported file constraints and video duration first; listen for trimming, silence or a mismatch with the visual action.
