A young woman stands alone on a quiet beach during a stormy sunset, holding an old photograph in her hand. Waves crash against the shore as strong wind moves her hair and coat. She slowly looks toward the horizon, then releases the photograph into the wind. The camera begins behind her shoulder and slowly circles around to reveal her emotional expression. Dark clouds gradually open as warm sunlight breaks through. Natural ocean movement, realistic wind simulation, soft backlight, shallow depth of field, muted cinematic color palette, subtle film grain, intimate emotional storytelling, poetic feature-film cinematography.

MiniMax H3-Developer Text-to-Video

MiniMax H3-Developer Text-to-Video turns a single text prompt into a smooth, cinematic clip with sound. Generate native 480P or 768P video, or select an ESR tier to enhance the output to a 1080P, 1440P, or 4K short edge. Describe the scene and the action, and the model generates the video together with a synchronized soundtrack (ambient sound, effects, and music) synthesized from what you described.

Why Choose This?

Text-driven generation Create a video from nothing but a prompt.
Native audio A matching soundtrack is generated alongside the video — no separate audio input needed.
Enhanced resolution output Generate native 480P or 768P video, or use ESR for a 1080P, 1440P, or 4K short edge.
Flexible aspect ratios Choose 16:9, 9:16, or 1:1 to match your target platform.
Selectable duration Produce 5–15s clips.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the video content, action, and scene audio
resolution	No	Video resolution. Available options: `768P` (default), `480P`, `1080p-esr`, `1440p-esr`, `4k-esr`. ESR tiers generate a native 768P source and enhance the output to the requested short edge.
ratio	No	Aspect ratio of the generated video. Available options: `16:9` (default), `9:16`, `1:1`
duration	No	Duration of the generated video in seconds. Integer between 5 and 15 (default 5)
prompt_expansion	No	Enable AI prompt expansion via H3 Context-IR. When `true`, your prompt is first expanded into a rich, structured description (shot, soundscape, music) before generation, and an additional per-token Context-IR fee applies. Default `false`: the prompt is used as-is with no extra charge.

How to Use

Write your prompt — describe the subject, motion, camera movement, and the sound of the scene.
Choose an aspect ratio — match your target platform (16:9, 9:16, or 1:1).
Set resolution and duration — balance quality against generation speed.
(Optional) Tune seed and steps — fix the seed for reproducibility, raise steps for quality.
Run — submit and download your video.

Best Use Cases

Concept & Ideation — Visualize an idea straight from a written description.
Marketing & Ads — Produce short promotional clips without footage or images.
Social Content — Generate vertical (9:16) or square (1:1) clips for social feeds.
Storytelling — Turn a scene description into an animated shot with matching sound.

Pro Tips

Be specific about the subject, movement, camera angle, and lighting.
Describe the scene's audio (traffic, music, crowd) to shape the generated soundtrack.
Keep one clear main action per prompt for the most coherent motion.
Pick the aspect ratio up front to avoid unwanted cropping later.

Notes

The prompt is required.
ESR tiers add an enhancement stage after native generation and may take longer than native resolutions.
Generation is asynchronous — submit, then poll for the finished video.
