MiniMax H3

MiniMax H3 is a multimodal AI video generator that produces high-definition video with integrated stereo sound from text, images, and audio clips. It works by processing multiple files at once. This maintains character consistency and specific motion styles. Creators use it to bypass traditional video editing pipelines by describing changes in natural language rather than using complex software.

Creative teams and solo content creators use this tool to build cinematic sequences without a full production crew. It solves the problem of silent AI video by generating synchronized background music and sound effects directly in the same pass as the visuals. This makes it useful for rapid prototyping in game development or social media marketing where audio-visual synchronization is critical.

Features

• Multimodal input support for up to 9 images, 3 videos, and 3 audio tracks per request
• Native 1440p resolution output at 24 frames per second
• Stereo audio generation including sound effects, music, and dialogue
• Instruction-based editing to swap backgrounds or relight scenes using text prompts
• Voice cloning from audio samples to keep character dialogue consistent
• Locked character continuity to maintain facial features across different shots
• Multiple aspect ratio support from 21:9 cinematic to 9:16 vertical formats

How to Use

1. Upload your reference files like character photos, background images, or motion clips to the chat interface.
2. Write a detailed prompt describing the action, camera movement, and specific sound elements you want.
3. Select your desired aspect ratio such as 16:9 for YouTube or 9:16 for TikTok.
4. Click Generate and wait for the model to render the video and synchronized audio track.
5. Use the follow-up chat to request specific edits, like changing a character's outfit or the lighting of the scene.
6. Download the final 1440p file once the output matches your requirements.

Use Cases

• A game developer creates a cinematic trailer by referencing character designs and gameplay UI in a single prompt.
• An e-commerce brand turns static product photos into 15-second social media ads with background music.
• A filmmaker generates moving storyboards with realistic camera pans and rack focus to pitch a scene.
