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.
