MiniMax H3 is a multimodal video model that generates high-resolution clips with synchronized audio. It helps content creators and designers build short cinematic sequences without needing separate tools for sound and visuals. Instead of just animating a static image, this model processes text, images, video, and audio files together to determine how a scene should look and sound.
Users can upload a first frame to set the composition and a voice sample to guide character speech. The model uses a specific architecture called H3-Omni Transformer to handle these different inputs at once. This approach keeps the motion of the video aligned with the rhythm of the audio, making the final output feel more coherent than typical AI video tools.
Key features
- Multimodal input support for combining text, images, and audio in one request
- Video duration settings between 4 and 15 seconds for precise shot timing
- Output resolution up to 2K for high-fidelity visual detail
- Native stereo audio generation including speech, ambient noise, and music
- H3-VAE compression that preserves fine details like text and interface elements
- Contextual Omni Representation to align motion with audio cues
- H3-Omni Transformer architecture for faster training and regeneration
How to use
- Write a prompt describing the subject, camera movement, and audio environment.
- Upload reference files such as a character image, a motion clip, or a voice sample.
- Assign specific roles to each file in the prompt text so the model knows what to follow.
- Select the desired duration, aspect ratio, and resolution settings.
- Click generate and wait for the model to process the unified request.
- Review the 2K output and adjust the prompt or references if the motion needs refinement.
Use cases
- Creating animated product posters where the graphic layout stays fixed while the background moves.
- Generating film opening titles with synchronized sound effects and music beats.
- Developing e-commerce product videos from flat images to show items in a 3D space.
- Building social media loops that include specific character voices and ambient sounds.
