MiniMax H3 Prompt Enhancer
An Ollama model that turns a short idea, and optionally a reference image, into a full audiovisual prompt for the MiniMax H3.
H3 generates video together with sound, so a good prompt describes both what is seen and what is heard. This model writes prompts in the structure from MiniMax's official video prompt writing guide: a timeline of shots with camera moves, speaker IDs and dialogue, a soundscape, and background music.
It is a prompt and parameter layer on top of an existing vision model. It contains no new weights and no MiniMax code or weights.
What it does
Give it an idea (and attach an image if you have one), get back only the finished prompt.
Task - You provide - Output starts with |
Text to video - Text only - integrated_multimodal_description:
Image to video - One image (used as the first frame) - The first-frame alignment line, then the three fields
First and last frame - Two images - The first-and-last-frame alignment line
Last frame - One image, plus "ending frame" in your text - The last-frame alignment line
Every prompt has the three core fields from the guide:
- integrated_multimodal_description: visuals, shots, camera, speech and sounds made by things in the scene, along a timeline.
- overall_soundscape: ambience, physical sounds, and non-verbal human sounds.
- non_diegetic_music: background music the characters cannot hear.
Behavior:
- Timeline format: [Shot 1] has no timestamp; later shots read [Shot 2] At 00:04.500, the camera cuts to ... with strictly increasing times inside the duration.
- Camera language: motion type, amplitude and speed, for example "The camera pushes in with small amplitude at slow speed".
- Speech: speakers get IDs such as (S1), and the words go in <d>[English] ...</d>, kept exactly as you wrote them. Voiceover and lip handling follow the guide.
- Image tasks: the style, subjects and composition come from your image, and the video develops forward from it (or lands on it, for a last frame).
- People: every person is described with an apparent age and ethnicity. If you give them, they are used exactly; otherwise they come from the image or the setting.
- No invented text: signs and labels appear only if you asked for them or they are in your image.
- Duration: use the one you state ("8 seconds"). The default is 8 seconds. Short clips are a single shot; longer clips get cuts.
