MiniMax H3 Highspeed R2V Video
byminimax
Create 4-15s videos from a scene description plus up to 12 reference files. H3 Highspeed R2V keeps characters, style, motion, and audio consistent.
Overview
MiniMax H3 Highspeed R2V generates short videos from text plus reference assets. It encodes your reference images, video clips, and audio clips, then guides generation to match them. It returns a single MP4 video with synchronized stereo audio, so you can keep the same subject across shots. MiniMax built it as a speed-focused variant of the H3 reference workflow.
What you can build
- Character-consistent clips from 1–9 reference images
- Product videos that keep the same item, colors, and materials across motion
- Style-controlled scenes using multiple reference images as a mood board
- Motion transfer using a reference clip for pacing and movement
- Simple video edits by providing a source clip as a reference and describing changes
- Voice or ambience matching by adding an audio reference alongside visual references
Inputs
- A scene description written as plain text. Refer to uploaded assets by order, like “Image 1” or “Video 1”.
- Up to 9 reference images for identity, props, wardrobe, or style. PNG and WEBP are commonly used.
- Up to 3 reference video clips for motion or editing guidance. MP4 clips are commonly used.
- Up to 3 reference audio clips for voice or sound cues. MP3 clips are commonly used.
- If you include audio references, you must also include at least 1 reference image or 1 reference video.
- A hard cap of 12 total reference files across images, videos, and audio combined.
- A target clip length in whole seconds, from 4 to 15 seconds.
- A target output resolution class: 480p or 768p.
- An aspect ratio selection: adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, or 9:16. Adaptive chooses a framing based on your inputs.
Outputs
- One MP4 video file.
- Video includes synchronized stereo audio.
- Audio is 32 kHz stereo.

Limitations
- Each generated video is limited to 15 seconds.

Image 1 is the teapot. A hand lifts this exact blue-and-white porcelain teapot and pours steaming golden tea into a small white cup on a sunlit wooden table, steam curling up in the window light, close-up shot. Keep the teapot design identical.Video Generation
Image 1 is the film camera. A young woman with shoulder-length brown hair, a straw hat and a white linen shirt walks through a sunny old-town market with this exact silver and black camera hanging from its brown leather strap, then lifts it to her eye and takes a photo of the colorful fruit stalls. The same woman throughout, the camera following her at chest height. Keep the camera design identical.Video Generation
Image 1 is the man. He walks through a busy night market in the rain wearing the same yellow raincoat, glowing food stalls and lanterns reflected in the wet street, raindrops falling, the camera moving backward in front of him.Video Generation
Image 1 is the toy sailboat. The same wooden toy sailboat, without its display stand, floats on its own hull and glides across a calm park pond on a sunny day, its white sails filling with a light breeze, small ripples spreading behind it, ducks swimming in the distance, low camera at water level. Keep the boat design identical.Video Generation
