MiniMax H3 Text-to-Video

MiniMax H3 Text-to-Video is a state-of-the-art AI video generation model that creates cinematic, high-fidelity videos directly from a text prompt. With crisp detail up to 2K, smooth natural motion, and flexible aspect ratios, it turns a single description into a polished clip.

Why Choose This?

  • High resolution output Generate videos in 2K quality.

  • Cinematic motion Fluid camera work and lifelike movement from a plain-text description.

  • Flexible aspect ratios 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 or adaptive to fit any platform.

  • Selectable duration Produce 4–15s clips.

Parameters

ParameterRequiredDescription
promptYesText description of the scene, subject, and action
resolutionYesVideo resolution. Available options: 768P, 2K
durationYesDuration of the generated video in seconds. Integer between 4 and 15. Available options: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
ratioYesAspect ratio of the generated video. For text-to-video, ratio is required and cannot be adaptive. Available options: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16
prompt_expansionNoEnable 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

  1. Write your prompt — describe the scene, subject, lighting, and motion in detail.
  2. Set resolution — higher for quality, lower for faster generation.
  3. Choose an aspect ratio — pick one of the supported ratios; adaptive is not available for text-to-video.
  4. Adjust duration — pick 5s or 10s.
  5. Run — submit and download your video.

Best Use Cases

  • Social Media Content — Short-form clips for TikTok, Reels, and Stories.
  • Concept Visualization — Bring ideas to life without filming.
  • Marketing Videos — Produce promotional content from text.
  • Storytelling — Create narrative scenes for creative projects.

Pro Tips

  • Be specific about camera angle, lighting, mood, and motion.
  • For text-to-video, ratio must be an explicit value (e.g. 16:9); adaptive is not supported for this mode.
  • Higher resolution (2K) suits hero shots; 768P is great for quick iteration.
  • Describe environmental effects (wind, smoke, golden-hour light) for richer results.

Notes

  • A prompt is required.
  • Supported durations between 4s and 15s.
  • Generation is asynchronous — submit, then poll for the finished video.
