Information as of August 6, 2026
What it can do
- Multimodal video generation
Combines text, images, video clips, and audio references in one request; the official page says users can mix up to 9 images, 3 video clips, and 3 audio tracks to generate a coherent video with native stereo sound.[1]
- Text to video
Turns prompts of up to 7,000 characters into videos with visuals, motion, and sound for storyboards, trailers, and social content.[1]
- Image to video
Animates photos or illustrations and supports first-and-last-frame image control so the model fills in motion between the provided start and end frames.[1]
- Reference-driven continuity
Can use character photos, motion clips, and style references together to keep faces on-model, copy choreography, and match a referenced visual style.[1]
- Conversational in-chat editing
Supports plain-language edits such as swapping characters or objects, replacing backgrounds, relighting scenes, rewriting dialogue, cloning voices, and preserving untouched parts of the video.[1]
- Native audio and voice cloning
The official page states that generations include stereo audio and describes using audio references for background music, synchronized sound effects, and voice tone cloning.[1]
- Commercial-oriented visual details
The product page highlights support for on-screen text, subtitles, brand marks, UI motion, product labels, packaging, and product detail rendering for ads and ecommerce use cases.[1]
- 1440p output
The official page highlights native 1440p video output with stereo audio.[1]
Where it fits best
- Creative teams generating short cinematic videos from text prompts, image references, video clips, and audio tracks in a single request.[1]
- Marketing and ecommerce users creating product showcase videos, ad creatives, feature explainers, and brand films from product imagery and brand references.[1]
- Game and entertainment creators producing game CG, first-person gameplay-style shots, character PVs, animated UI demos, stylized animation, trailers, and short drama concepts.[1]
Important considerations
- The official page excerpt describes input limits of up to 9 images, 3 video clips, 3 audio tracks, and video input of 15 seconds or less for a MiniMax H3 request.[1]
- The supplied official context confirms the product is free to try or starts free, but it does not provide detailed plan tiers, paid pricing, billing period, or usage limits.[1]
- No official documentation, API reference, deployment options, or open-source repository URL was supplied, so availability can only be verified as the hosted product website.[1]
