Three distinct creation modes
Start MiniMax H3 with text, first or last frames, or multimodal references. Buble changes uploads with the mode to prevent incompatible fields.

MiniMax H3 AI Video Generator
Use MiniMax H3 on Buble to create native 2K video from text, first or last frames, or mixed image, video, and audio references. Choose 4-15 seconds and keep its three input workflows separate so every request matches the provider contract.
Original videos made with MiniMax H3
These five original Buble generations were created through the live MiniMax H3 integration at native 2K, four seconds, and 16:9. They test weather, character staging, transparent materials, high-speed tracking, architectural scale, and animal motion. Every result is stored on Buble R2 with its own poster.
Prompt
A lone traveler in a yellow raincoat waits on a rural train platform at blue hour. Wind moves the coat and wet grass as an old train enters through mist. Smooth lateral tracking shot, believable rain, warm carriage light, quiet cinematic tension, natural station ambience, no text.
Verified Capabilities
What MiniMax H3 supports on Buble
The current MiniMax H3 configuration follows the APIMart request contract. These are usable controls, not inferred features from a launch announcement.
Native 2K delivery
Every MiniMax H3 request uses the documented 2K resolution, without invented lower-resolution options.
Four to fifteen seconds
Choose any whole-second duration from 4 through 15 for a complete short shot.
Broad output framing
Text mode offers six ratios. Frame mode inherits the image shape; reference mode supports adaptive or explicit framing.
Mixed reference context
Reference mode accepts 9 images, 3 videos, and 3 audio clips. Audio requires a reference image or video.
Optional AIGC watermark
Keep the documented AIGC watermark off for a clean render or enable it when publishing policy requires disclosure.
Input Mode Guide
Choose the right MiniMax H3 workflow
Text explores a new shot, frames control its endpoints, and references carry visual or audiovisual context into a new composition.
| Decision | Text to Video | Frame Guided | Multimodal Reference |
|---|---|---|---|
| Starting material | Prompt only | First frame, last frame, or both | Images, videos, and optional audio |
| Creative purpose | Invent a scene from a written brief | Control where motion begins or ends | Carry subject, style, movement, or sound context |
| Aspect ratio | Choose one of six concrete ratios | Inherited from the input frame | Adaptive by default or explicitly selected |
| Media capacity | No upload required | One first frame and one last frame | Up to 9 images, 3 videos, and 3 audio files |
| Important rule | Prompt remains required | Cannot be combined with reference fields | Audio must accompany an image or video |
Production Workflow
A practical MiniMax H3 workflow
Treat each generation as one directed shot and make the input decision before writing details.
Step 01
Decide what must stay fixed
Use text for exploration, frames for planned endpoints, and references when MiniMax H3 should carry recognizable context.
Step 02
Prepare only relevant assets
Crop images, trim reference clips to useful moments, and remove conflicting material. More files do not guarantee fidelity.
Step 03
Write a shot-level prompt
Describe subject, one action, environment, camera, timing, light, sound, and what must remain stable.
Step 04
Generate, review, and archive
Check picture and sound, then save successful MiniMax H3 output instead of relying on a temporary provider URL.
Practical Use Cases
Where MiniMax H3 fits best
MiniMax H3 fits high-resolution short shots with a clear reason for using text, frames, or references.
Product hero shots
Direct a reveal, orbit, macro detail, or environmental shot around clean product references.
Character continuity tests
Use consistent views to keep a character, wardrobe, or creature recognizable through motion.
First-to-last transitions
Give MiniMax H3 planned opening and ending frames for reveals, transformations, or precise landing compositions.
Sound-aware visual concepts
Pair visual references with short audio when timing, ambience, or performance should influence the clip.
Campaign format variants
Prototype landscape, square, portrait, and ultrawide compositions separately instead of relying on a late crop.
Previsualization and pitch work
Use MiniMax H3 to test camera, blocking, atmosphere, and pacing before expensive production.
Prompt Method
How to prompt MiniMax H3 and judge the actual render
The adjacent clip is a rejected MiniMax H3 iteration: a wristwatch became a ring-like object. It shows why prompts must be judged against the render, not the intention.
Name subject and action first
Open with the visible subject and one action. Concrete verbs give MiniMax H3 a clearer timeline.
Compose space, light, and camera
Define space, light, shot size, camera path, pacing, and the resolution point. One movement often reads better than several cuts.
Give every reference a job
State which image defines identity, which clip supplies motion, and what audio contributes. Never leave reference roles ambiguous.
Define stability, then review
List details that must not drift, compare them with the result, and reject an attractive take when it misses the brief.
Limits and Review
What to verify before publishing MiniMax H3 output
A valid request still needs creative, legal, and technical review before publication.
Input limits are cumulative
The request body is limited to 64 MB. Reference video and reference audio each have a 15-second aggregate limit.
Mode fields are mutually exclusive
Do not combine frame controls with multimodal reference fields; the provider rejects mixed MiniMax H3 modes.
References guide rather than guarantee
Logos, measurements, hands, crowds, typography, and fast transformations can drift. Simplify or split precision-critical shots.
Rights and consent remain your responsibility
Confirm source rights, consent, trademarks, safety, and required synthetic-media disclosure before publishing.
