MiniMax H3 Reference to Video

Reference-guided 2K video generation for stronger consistency, motion control, and scene continuity.

MiniMax H3 Reference to Video is a multimodal image-to-video model that generates coherent 2K videos from natural-language prompts plus reference media. By combining text with images, videos, and optional audio, it offers stronger control over subject identity, motion, timing, visual style, and overall scene progression—while also delivering no cold start behavior and cost-efficient production.

🚀 Key Features

Multimodal reference guidance: Generate videos from a Prompt combined with reference images, reference videos, and optional reference audio for more controllable results.
Stronger subject consistency: Use reference images to preserve characters, products, objects, or brand visuals across the generated video.
Motion and camera guidance: Reference videos help steer movement, pacing, interactions, and camera behavior for more directed outputs.
Native 2K output: Produces high-resolution 2K videos suitable for polished creative, commercial, and concept work.
Flexible Aspect Ratio support: Supports 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, and Adaptive for cinematic, social, square, and vertical formats.
No cold start, production-friendly pricing: Well suited for reliable generation workflows, rapid iteration, and scalable content creation.

Character and IP consistency workflows: Maintain a stable visual identity for people, avatars, mascots, or branded subjects across generated clips.
Storyboarding and concept development: Rapidly prototype scenes, camera moves, and visual direction from written ideas plus reference media.
Social and mobile-first content: Produce vertical, square, or widescreen videos tailored to different publishing channels.

🔗 Related Models

MiniMax H3 Text-to-Video: Best for generating high-resolution video directly from text-only prompts.
MiniMax H3 Image-to-Video: Best for generating video from a first-frame image plus a Prompt.

Best Practices

Use clear, relevant reference images when subject identity, product detail, or style consistency matters most.
Use reference videos when motion, pacing, interaction, or camera movement is the priority.
Keep the Prompt focused on visible action, scene progression, camera language, lighting, and mood.
Start with shorter Duration values for fast iteration, then extend length for more developed scenes.
Match the Aspect Ratio to the target channel: 16:9 for standard widescreen, 9:16 for mobile vertical, and 1:1 for square social content.
