The MiniMax H3 Video Model as a Complete 2K Creation Suite
MiniMax H3 is an open-weight omni-modal model available on fal.ai from launch. Text, stills, motion, and sound share one context, so a single request can return 2K footage with two-channel sound in up to 15 seconds. It also handles targeted edits, readable text and interface rendering, and up to 12 multimodal reference files per job.
- Unified Context Across Every Input TypeYou can pass as many as nine stills, three footage snippets, and three audio files in one request. The model blends character identity, acting, camera language, and audio timing into a single consistent result.
- Crisp Two-Channel Audio, Generated AutomaticallyEvery output carries original music, spoken lines, effects, and room tone aligned to the edit; reference recordings can also transfer or clone a specific voice.
- Surgical Edits That Leave the Scene Untouched ElsewhereSwap a product, update a sign, replace dialogue, or turn day into night—the algorithm changes only the selected region while all other elements stay intact.
A 3-Step Runbook for the MiniMax H3 Video Model API
Follow this 3-step guide to generate 2K videos with stereo sound through the minimax h3 video model API.
Core Capabilities of the MiniMax H3 Video Model
The minimax h3 video model bundles three generation modes, a unified multimodal context, stereo audio, targeted edits, legible text, and usage-based billing into one production stack on fal.ai.
Three Ways to Start a Video
Text-to-video, image-to-video with optional first/last-frame locks, and reference-to-video cover different creative workflows.
Twelve References Per Request
Bundle nine images, three clips, and three audio tracks in one task. The system derives subject details, performance, camera motion, composition, and editing rhythm from those files.
Readable Text and Interface Animation
Clean captions, end cards, brand marks, and even working UI—landing pages, menus, HUDs, typography—can be rendered accurately.
Long Prompts for Full Scene Control
A single request can hold up to 7,000 characters of instructions, giving you detailed command over the whole shot.
2K Resolution at 24fps
Rendered on a 1440px short edge, clips run as long as 15 seconds at 24 fps, with six aspect ratios plus an adaptive mode.
Pay for What You Use
There are no fixed plans or minimums; billing is per generation and commercial use of the output is permitted.
Questions About the MiniMax H3 Video Model, Answered
Answers to the most common questions about this fal.ai model, including endpoints, output specs, audio generation, references, and usage rights.
What exactly is MiniMax H3?
MiniMax H3 is an open-weight omni-modal generator hosted on fal.ai from launch. It handles text, still images, video, and sound in one context and can produce up to 15 seconds of 2K footage with two-channel audio.
Which generation modes are available?
There are three paths: prompt-to-video, picture-to-video with optional first/last-frame constraints, and reference-to-video. The reference mode preserves subject identity, visual style, movement, camera angles, and voice characteristics from your source files.
What output specifications should I expect?
The service renders 2K video (1440px on the short side) at 24fps. Clips last 5-15 seconds and can be exported in 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, or adaptive aspect ratio.
Does the model generate audio?
Yes—every generation includes two-channel audio: original music, dialogue, effects, and ambience synced to the edit. Voice transfer or cloning can also be applied from references.
How many reference files can I provide?
You can supply up to 12 files: 9 images, 3 video clips (each 2-15s), and 3 audio tracks (each 2-15s). Any audio must be paired with at least one image or clip.
Can I use the generated content for commercial work?
Yes. Content produced through the fal.ai API with the MiniMax H3 video model is allowed in commercial projects, subject to fal.ai's terms of service.
