MiniMax H3 video generator guide

Create with MiniMax H3, from first prompt to final frame

MiniMax H3 is an open, general-purpose multimodal video model released by MiniMax on July 31, 2026. It reads text, images, video and audio as one context instead of treating every input as a separate tool. TryH3 turns those verified model capabilities into a focused browser workflow: begin with text to video, animate an image, control a first or last frame, or direct a new shot with multimodal references. The sections below explain what each mode actually does, which controls are available, and where every technical claim comes from.

Text to video from a written direction

Text-to-video mode starts with one required prompt and no media input. Describe the subject, action, environment, camera behavior, visual style and sound you want; then choose a duration and aspect ratio. MiniMax’s H3 documentation lists six fixed ratios for text generation: 21:9, 16:9, 4:3, 1:1, 3:4 and 9:16. That makes the same MiniMax H3 AI video generator useful for widescreen concepts, square feeds and vertical shorts. Clear relationships matter more than a pile of adjectives, so explain who does what, where the camera moves and what the audience should hear.

Image to video with first and last frames

Image-to-video mode combines a prompt with a first frame, a last frame, or both. A first frame gives H3 the opening composition to bring to life. A last frame defines where the shot should arrive. Using both asks the model to create a natural transition between two supplied moments. The official API treats this as a distinct mode from reference generation, and the source image determines the output aspect ratio automatically. Use a clean, well-composed image and write about movement rather than redescribing every visible detail: subject motion, camera direction, environmental motion and the intended end state are the most useful instructions.

Reference to video across image, video and audio

Reference-to-video is for direction that needs more context than a single opening frame. Official MiniMax documentation says references can guide a character, motion, camera style, visual style, voice or editing rhythm. H3 accepts up to nine reference images, three reference videos and three audio clips, with a maximum of twelve files in one request. Reference audio cannot be used alone; it must be accompanied by an image or video. Tell the model exactly how each reference relates to the requested result—for example, use one image for identity, one video for camera movement and one audio clip for voice timbre. This relationship-based prompting matches H3’s unified multimodal design.

Verified H3 output specifications

MiniMax’s current H3 API documents one output resolution: 2K. Duration is selectable in whole-second values from 4 through 15 seconds. Text-to-video supports six fixed aspect ratios; image-to-video follows the supplied frame; reference generation can use a fixed ratio or adaptive selection. Every request needs a non-empty text prompt, which may contain up to 7,000 characters. The model’s launch paper says video can be generated with native stereo sound and highlights instruction following, accurate text and brand rendering, and video-to-video motion transfer. These are model capabilities, not guarantees that every generation will be perfect, so plan to review and iterate.

A practical MiniMax H3 prompt structure

A useful prompt reads like compact direction: subject and setting first, action second, camera and composition third, then lighting, style, pacing and sound. State timing or shot order when it matters. For image to video, describe how the existing frame changes instead of asking H3 to rebuild it. For reference generation, name the role of each asset in plain language and avoid conflicting instructions. If readable words or a logo matter, quote the exact text and explain when it appears, while still checking the result before publishing. Generate one clear idea first, identify the weakest element, and revise only the instruction that controls it.

What “free online” means on TryH3

You can try the MiniMax H3 video generator free online with the welcome credits offered to eligible new TryH3 accounts. The current offer is shown before you generate, no payment card is required to create an account, and the studio displays the credit quote for the selected duration and inputs. Free does not mean unlimited generation: H3 video inference consumes credits, longer clips cost more, and an offer may change. Failed generation jobs are refunded automatically by TryH3. This makes the free allocation useful for testing a concise text-to-video prompt or a controlled image-to-video idea before choosing a paid plan.

Frequently asked questions

Everything you need to know before your first generation.

What is TryH3?

TryH3 is an AI video generator powered by MiniMax H3. Type a prompt or upload an image and H3 renders a native 2K clip with synchronized audio in about 1-3 minutes.

How do credits work?

Credits renew with your monthly or yearly subscription, and unused credits roll over. Each generation is quoted from its model, duration, resolution, audio tier and reference inputs; failed jobs are refunded automatically.

How long and how sharp are the videos?

Clips run 4-15 seconds at up to native 2K resolution, with sound. Choose from 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9.

Can I use my own images?

Yes. Switch to Image to Video and upload a first frame. H3 animates it while your text prompt directs the motion.

Can I use the videos commercially?

Yes. Videos generated on a paid subscription include commercial use for ads, client work and monetized content.

How long does a generation take?

Usually 1-3 minutes depending on duration and queue load. Your video appears on the generator page as soon as it is ready.

Your first videos are on us.

New accounts get 10 free credits, enough for one 5-second Seedance 1.5 Pro video at 480p with 1 credit left. No card required.
