MiniMax H3 is a MiniMax video generation model for multi-shot sequences, synced audio, camera control, keyframe editing, and consistent narrative structure.
On Pollo API, developers can access MiniMax H3 for text-to-video, image-to-video, and reference-to-video workflows through a standard API integration.
Key Features of MiniMax H3 API
Multi-Shot Generation
MiniMax H3 supports video outputs composed of multiple connected shots, which can help represent scene progression, actions, or short narrative sequences.
Synced Audio
The model supports native synced audio, allowing prompts to include sound cues, ambience, speech direction, or timing-related audio requirements.
Camera Control
MiniMax H3 allows camera movement and framing to be described in prompts, including shot transitions, angle changes, and subject tracking.
Keyframe Editing
Keyframe editing support helps define important visual states in a video, such as opening composition, ending frame, or major scene transitions.
Asset Referencing
Reference-based generation can use uploaded assets to guide subject appearance, visual style, composition, or continuity across generated clips.
Use Cases of MiniMax H3 API
Narrative Video Clips: Generate short videos with multiple connected scene beats or visual transitions.
Image-to-Video Workflows: Animate still images while keeping the source subject or composition as a reference.
Reference-to-Video Creation: Use reference assets to guide appearance, framing, style, or scene structure.
Product Demonstrations: Create short product clips that show movement, interaction, or step-based usage.
Storyboard Previews: Convert written scene descriptions into moving drafts for planning or review.
Social Video Assets: Generate short clips with camera movement, audio cues, and defined ending frames.
Brand Motion Tests: Produce draft video concepts using reference images, logos, packaging, or visual guidelines.
Creative Tool Integration: Add MiniMax H3 to applications that need prompt, image, and reference-based video generation.
How to Use MiniMax H3 API
Get an API Key: Create a Pollo API account and generate your API key from the developer dashboard.
Choose the Model: Use the MiniMax H3 route, /generation/minimax/minimax-h3, for the generation request.
Add Your Inputs: Provide a prompt, with optional fields such as image, imageTail, resolution, length, and aspectRatio.
Generate and Retrieve: Submit the request, then use the returned taskId or webhook result to check and retrieve the generated video.
Prompting Best Practices for MiniMax H3 API
For MiniMax H3, prompts should define the scene sequence, reference purpose, camera behavior, audio direction, and target ending frame in clear terms.
A Simple Prompt Formula
scene sequence + subject action + reference purpose + camera movement + audio direction + ending frame
What You Should Notice
Scene Order: Describe how the video should begin, progress, and end.
Reference Usage: State whether the reference controls subject identity, composition, style, or final-frame direction.
Camera Direction: Include framing, movement, angle, or transition details when they affect the result.
Audio Requirements: Describe ambience, sound effects, dialogue tone, or timing when synced audio is needed.
Ending Frame: Define the final visual state to make the output easier to evaluate or edit.
Example Prompts
Museum Exhibit Sequence
"Create a short museum exhibit video. Start with a close-up of an artifact case, move to visitors observing the display, add quiet room ambience, and end on a wide shot of the exhibition title wall."
Cooking Clip From Image
"Use the uploaded dish image as the final plating reference. Show vegetables being prepared, sauce added to a pan, steam rising, and an overhead camera movement ending on the completed dish."
Game Environment Preview
"Generate a short game environment preview. Begin at a closed stone gate, track forward as light appears through the cracks, cut to an underground hall, add low ambience, and end on a glowing checkpoint."
Character Reference Scene
"Use the reference image for character appearance. Show the character entering a workshop, turning on a desk lamp, picking up a small mechanical part, and ending with a close-up under warm light."
Product Assembly Clip
"Create a compact product assembly video. Show a foldable lamp base opening, the arm extending, the shade attaching, and the light turning on, with small mechanical sounds and a final side-view frame."
