MiniMax H3 Lite Text to Video

MiniMax H3 Lite Text to Video turns a single written prompt into a short video clip. It is the lightweight tier of MiniMax's H3 family — the omni-modal generation model built to follow instructions closely — tuned for fast drafts and high-volume generation at 480P and 768P.

What is MiniMax H3 Lite Text to Video?

H3 Lite is the fast, lightweight member of the MiniMax H3 lineup. It reads your description of a subject, setting, and motion and renders a continuous 4–15 second shot, up to 768P, in the aspect ratio you choose. Because it shares the H3 architecture, clips drafted on Lite translate predictably when you re-run a final pass on the higher-fidelity H3 or Max tiers, making it a practical engine for iterating on shot ideas before you commit to a hero render.

Key Features

• •Text-to-video from a single prompt — no reference image or video required
• •480P or 768P output, 4–15 second duration, whole seconds only
• •Six aspect ratios: 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9
• •Strong instruction following — the named subject, wardrobe, setting, and motion appear as written
• •Prompts up to 7,000 characters for detailed, multi-element scenes

Best Use Cases

H3 Lite shines when you need many clips quickly: storyboards and animatics, social-first vertical video, product and fashion teasers, and A/B testing competing prompt ideas. In testing, a detailed fashion-runway prompt produced a clean 768P clip with physically coherent fabric and body motion — evidence that complex, moving materials hold up at the Lite tier. Use it to explore, then promote the winning prompt to a higher-resolution tier for delivery.

Prompt Tips and Output Quality

Write concrete nouns over adjectives and commit to one clear, verb-driven action — a stride, a pour, a spin — so the motion reads cleanly in the first seconds. Name the material, place, or era when it matters, and keep lighting to a single phrase. Set the aspect ratio deliberately (it is required and cannot be adaptive), and choose 768P for presentation or 480P for rapid drafts.

How to Use MiniMax H3 Lite Text to Video

MiniMax H3 Lite generates a short video from a text prompt alone. Describe the scene you want — who or what, where, and the single action that should play out — and the model renders a continuous 4–15 second clip at up to 768P.

Write the prompt

Lead with a concrete subject and setting, then state one clear, verb-driven action (a stride, a pour, a spin, a turn). Add a material, place, or era where it sharpens the image, and keep lighting to a single phrase. Avoid piling on simultaneous actions — one legible motion reads far better than three competing ones. Prompts can run up to 7,000 characters, so you have room to specify wardrobe, camera framing, and background.

Choose your settings

• •ratio — required for text-to-video and cannot be adaptive. Use 16:9 for landscape and presentation, 9:16 for social, 1:1 for feeds.
• •duration — 4 to 15 seconds. Six seconds comfortably fits a single beat such as a walk-and-turn.
• •resolution — 480P for fast drafts and batches, 768P for your best-looking output. 2K is reserved for the base H3 tier.

Recommended Settings

For the strongest first result, the tested default is ratio 16:9, duration 6, resolution 768P. That combination produced a clean, artifact-free clip with physically coherent motion on a detailed fashion-runway prompt. Drop to 480P when you are generating many variations and only need to judge composition and motion; move up to the base H3 or Max tiers when you need a final, higher-fidelity render of a prompt that already works.

Workflow tip

Treat H3 Lite as your iteration loop: draft several prompt variations quickly, pick the one whose motion and framing land, then re-run that exact prompt on a higher tier for the final deliverable.

Examples to try

Each example below ran end to end on this page at the settings shown — the same 16:9 framing and 768P resolution, each in a single 5–6 second beat — so the clip you see is exactly what the prompt produced.

• •Coherent fabric motion from a single prompt (default). Prompt: "A runway model strides down a glossy black catwalk in a floor-length crimson silk gown with a long sweeping train. The fabric billows and snaps with each step, and she pivots hard at the end so the train whips across the polished floor. Overhead spotlights rake the runway." The silk train billows and whips through the pivot and stays coherent for the full clip. Tip: name the fabric and one clear action, and let 6s hold a walk-and-turn.
• •Instruction following with a named camera move. Prompt: "An empty opera house: a grand marble staircase sweeps past gilded balconies and rows of red velvet seats toward a glowing crystal chandelier. [zoom]" Every named element appears and the camera pushes in on cue. Tip: append a bracketed tag — [zoom], [pan] or [static] — right after the key description to steer the shot.
• •Physically dynamic fluid motion. Prompt: "Molten chocolate streams from a steel spout over a round sponge cake on a white plate, flooding down the sides and pooling at the base; a dusting of cocoa powder drifts over the top." The chocolate flows, sheets down the sides and pools like real liquid. Tip: describe one pour and the surface it lands on rather than stacking several motions.

Want more to try? "A glassblower turns a molten gob on a blowpipe as it glows and sags", "A paper boat drifts down a rain-filled gutter, water rushing past it. [pan]", or "Confetti bursts over a packed stadium as the final whistle blows."

What resolutions does H3 Lite support?

480P and 768P. 2K is reserved for the base H3 tier.

How long can a clip be?

Any whole number of seconds from 4 to 15.

Can I feed an image?

This endpoint is text-only. Use the image-to-video or reference-to-video siblings for image, video, or audio inputs.

Which aspect ratios are available?

16:9, 9:16, 1:1, 4:3, 3:4, and 21:9.

Does it follow detailed prompts?

Yes — H3 is built for instruction following, so specific prompts outperform vague ones.
