Why use MiniMax H3
MiniMax H3 AI video generator
MiniMax H3 gives you a browser-based studio for short AI video. Write a prompt, add a first and last frame, or upload reference images, a video and audio, and the page picks the right generation mode for what you provided. It runs online, so there is nothing to install.
MiniMax H3 text to video
Describe the subject, the action, the camera and the mood, choose an aspect ratio of 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9, and MiniMax H3 renders a clip of 4 to 15 seconds. Longer prompts with a timeline of beats work well for planned shots.
MiniMax H3 first and last frame video
Add a first frame to animate a picture, and add a last frame as well to define how the shot ends. The model then moves between the two images. When you provide frames they define the shape of the video, so the aspect ratio option is hidden.
MiniMax H3 reference to video
Upload up to 5 reference images, one reference video and one reference audio file to guide a generation. Use them to keep a character consistent, borrow camera movement from a clip or match a piece of audio. Reference videos can be MP4 or MOV files of up to 50MB and 15 seconds.
768P or 2K output
Choose 768P for quick drafts and 2K when you want more detail. The total credits for your choices are shown on the Generate button before you start.
Tips for better MiniMax H3 prompts
MiniMax H3 follows detailed prompts well, so it can help to describe a clip as a short timeline: what happens at the start, in the middle and at the end, plus the camera movement and the lighting. When you use references, say what each one is for, for example which image is the character and which clip supplies the camera movement. Keep the prompt within 5,000 characters.
Credits and failed generations with MiniMax H3
The credits for a clip are taken when it is submitted and shown on the Generate button beforehand, including the length of any reference video. If a video fails it is retried automatically once without extra charge, and if it still fails the credits go back to your balance. You can leave the page while a video renders and come back to it.
What you can make with MiniMax H3
MiniMax H3 is a flexible choice for planned shots. Use text to video for a new idea, first and last frames for a transition between two pictures, and reference mode for a character that has to stay consistent or a shot that should borrow movement from a clip.
MiniMax H3 pricing per second
MiniMax H3 is billed per second: 19 credits per second at 768P and 30 credits per second at 2K. If you add a reference video, its length is billed at the same rate as the output. A 5 second text to video clip costs 95 credits at 768P or 150 at 2K.
