Key Benefits of the MiniMax H3 Video Model for Creators
MiniMax's open-weight omni-modal AI, the minimax h3 video model, is available through fal.ai as a launch partner. It processes text, pictures, footage, and sound together, then outputs up to 15 seconds of 2K video with built-in stereo audio. You also get targeted regional edits, readable text in scenes, and up to 12 reference inputs per request.
- Unified Input for All Media TypesFeed it up to nine pictures, three footage clips, and three audio files in a single request. It fuses character traits, acting, camera motion, and audio into one seamless output.
- Built-in Two-Channel SoundEach generation includes original music, spoken lines, foley, and background noise matched to the scene. You can also transfer or clone a voice from sample audio.
- Targeted Scene AdjustmentsModify specific areas of a video — swap a product, alter text on a sign, change the dialogue, or turn daylight into night — while the rest of the frame remains unchanged.
Three Steps to Generate with the MiniMax H3 Video Model
Use the minimax h3 video model API via this quick 3-step workflow to create 2K clips with audible sound.
Capabilities of the MiniMax H3 Video Model
The minimax h3 video model brings together three endpoints, a shared multimodal context, embedded stereo sound, targeted scene edits, legible text rendering, and usage-based billing. It forms an end-to-end 2K video workflow on fal.ai.
Three API Routes for Different Start Points
Start from text, from an image with optional start/end frames, or from reference media. All three pathways are available to match any production style.
Support for 12 Reference Files
Mix up to nine images, three clips, and three audio tracks. The model extracts character identity, acting style, camera movement, framing, and pacing from those references.
Clear On-Screen Text and UI Animation
Generate crisp captions, end credits, and brand logos, and animate actual interfaces like landing pages, game menus, heads-up displays, and kinetic typography.
Extended Prompt Capacity
Describe an entire storyboard in one call. Prompts can be up to 7,000 characters, letting you control every part of a scene.
2K Quality at 24 Frames per Second
Receive footage at 2K resolution (1440px short edge) and up to 15 seconds at 24 fps. Six aspect ratios plus adaptive sizing are supported.
Flexible Usage-Based Pricing
Access the model through a serverless, pay-as-you-go API without minimums or monthly fees. Generated content includes commercial usage rights.
Frequently Asked Questions About the MiniMax H3 Video Model
Everything you need to know about using the MiniMax H3 video model through fal.ai.
What exactly is the MiniMax H3 video model?
It's MiniMax's publicly weighted, all-in-one content generation model, available on fal.ai from day one. The system works with text, pictures, video, and sound in one shared workspace, producing 2K video clips with bundled stereo audio that last up to 15 seconds.
Which generation modes are available?
You get three different starting points with this model: pure text prompts, images (optionally paired with starting and ending frames), and reference media that preserves the subject, visual style, motion, camera angles, and voice.
What video quality and length are possible?
This model renders 2K footage with a 1440px short edge at 24 frames per second. Clips run between 5 and 15 seconds, and you can select from 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, or adaptive ratios.
Can the model create sound?
Absolutely — each output includes built-in stereo sound: original score, spoken dialogue, effects, and ambience matched to the footage. You can also transfer or clone a voice from reference audio.
How many reference media files can I provide?
You can supply as many as 12 media files per generation: nine pictures, three video clips (2 to 15 seconds each), and three audio tracks (2 to 15 seconds each). Audio files need at least one accompanying image or video.
Is commercial use permitted?
Yes. Content created via the fal.ai API using this model can be used in commercial work, subject to fal.ai's service terms.
