MiniMax H3 / テキストから動画
Open-weight general-purpose multimodal video model. Unifies text, image, video, and audio understanding in a single context window, generating up to 2K resolution, 15-second clips with native stereo audio at 24fps. Supports multimodal reference inputs: up to 9 images, 3 videos, and 3 audio clips (12 total references) per generation. Features first-frame, last-frame, and full reference modes with conversational editing capabilities.
MiniMax H35-Mode Cinematic Video with 2K Output
MiniMax H3 is a multimodal video foundation model with five generation modes — text, image, end-frame, start-and-end-frame, and reference conditioning — plus native 2K resolution and up to 15-second clips.
Multimodal Video Architecture
One model for every conditioning path — from pure text to multi-reference cinematography.
Five Conditioning Modes
Text-to-video, image-to-video, end-frame, start-and-end-frame, and multimodal reference-to-video — switch modes without changing providers.
Native 2K Resolution
Ship 768P for drafts and social, or promote hero placements to 2K without a separate upscaler pass.
Start & End Frame Bridges
Land exactly on a target end frame for match cuts, product morphs, and seamless scene transitions.
Cinematic Ratio Suite
Text-to-video supports 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16; reference mode also allows adaptive framing.
How It Works
From brief to finished multimodal clip.
Pick a Mode
Start from text, a still, an end frame, both frames, or multimodal references.
Set Canvas & Length
Choose 768P or 2K, aspect ratio, and 4–15 second duration for the placement.
Condition with References
In reference mode, feed stills or motion cues that lock identity and style.
Deliver & Chain
Pull the finished clip and bridge into the next shot with end-frame continuity.
H3 Production Domains
Where multimodal control replaces stitched pipelines.
Brand Film Previs
Reference-conditioned previs before full live-action shoots.
Product Morph Ads
End-frame and dual-frame transitions for packshot reveals.
Ultra-Wide Storytelling
Native 21:9 cinematic boards for hero brand placements.
Social Vertical Cuts
9:16 clips up to 15 seconds for Reels and TikTok.
Prompt & Usage Tips
Get cleaner first-pass H3 generations.
If you need a bridge, mention the end composition in the prompt so the model aims for that landing frame.
Draft at 768P, promote only final hero placements to 2K to control spend.
Reference mode is strongest when each image has a single clear job — identity, style, or scene.
H3 Multimodal Quickstart
Submit text or reference-driven clips with native 2K support.
