MiniMax H3 AI Video Generator

MiniMax H3 is a new-generation general-purpose multimodal video model. Instead of treating image, video, and audio tasks separately, H3 understands text, images, video clips, and audio together as one creative context, then generates coherent videos with native stereo sound. It handles generation, reference-based creation, and precise editing in a single model — a step from specialized task models toward general multimodal intelligence. In practice, that means you describe an outcome once and MiniMax H3 handles the visuals, motion, camera, and sound as one job.

Yes. You can try the MiniMax H3 AI video generator for free — no credit card required. Free credits on signup let you test text to video, image to video, and instruction-based editing with the full model, not a watered-down version. When you need more generations, longer queues, or commercial rights, paid plans unlock additional credits and faster processing.

Type a description of your video, or upload reference images, clips, and audio. Choose an aspect ratio, click Generate, and H3 delivers a finished video with sound in minutes. You can then refine it with plain-language edit instructions until it's exactly right.

H3 accepts text prompts up to 7,000 characters, up to 9 reference images, up to 3 video clips (15 seconds total), and up to 3 audio tracks — with a combined cap of 12 files per request. Supported formats include JPG, PNG, WEBP, HEIC for images, H.264/H.265 for video, and WAV/MP3 for audio.

Each generation produces a 5 to 15 second video at 24 FPS. Output goes up to 1440p — for a 21:9 frame that's roughly 2976×1248 pixels. Every video includes native two-channel stereo audio.

Yes. Unlike most AI video generators that output silent clips, every MiniMax H3 result ships with native stereo audio — ambience, sound effects, music, and synced dialogue. You can also provide a reference audio clip to clone a voice for your characters.

MiniMax H3 supports 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. In reference mode you can also let H3 choose the best ratio automatically. With first/last frame images, output follows your input image's original ratio.

Yes. Image to video is a core H3 workflow. Upload one image as a starting frame, or two images as first and last frames, and H3 animates natural motion between them. You can also use up to 9 images as identity and style references.

Yes, and this is where H3 stands apart. Upload a clip and describe your change: swap a character, remove an object, replace the background, change the lighting to night, or rewrite a line of dialogue. H3 applies the edit precisely while keeping everything else stable.

Videos you generate on a paid plan come with commercial usage rights, suitable for ads, e-commerce listings, social campaigns, brand films, and client work. MiniMax H3 was designed for commercial-grade output — accurate brand text, product details, and UI elements — so the license matches how teams actually use it. Check our commercial license page for full details.

Three things: true multimodal input (mix images, video, and audio in one request), native audio on every output, and instruction-based editing that keeps unedited content stable. Most tools do one of these; the MiniMax H3 video generator does all three in a single model.

Be specific about subject, action, camera, lighting, and sound. H3 responds to real film language — 'rack focus', 'handheld', 'hard cut', 'title card fades in'. Longer, structured prompts (up to 7,000 characters) produce more controlled results. Reference files reduce how much you need to describe.

Most MiniMax H3 videos are ready within a few minutes, depending on length, resolution, and queue load. A 5-second 16:9 clip typically finishes faster than a 15-second 1440p cinematic shot. Paid plans get priority processing for faster turnaround, which matters when you are iterating on a deadline.

No. There is no timeline, no keyframes, and no software to learn. If you can describe what you want in a sentence, you can direct MiniMax H3. Refinements are also plain language — just say what to change and the model handles the rest. Beginners get watchable results on their first try, and professionals get precise control when they push deeper.

H3 is especially strong at game content, stylized animation, product and e-commerce marketing, and cinematic film work. It renders on-screen text, brand marks, UI elements, and product details accurately — which matters for real commercial use.

Click Generate Free on this page, type your first idea, and watch MiniMax H3 turn it into a video with sound. Start simple — one subject, one action, one camera move — then layer in references and edits as you get comfortable. Your free credits are waiting: no download, no setup, no card.
