MiniMax H3 I2V with Integrated Prompt Enhancer
This Image-to-Video workflow for MiniMax H3 uses a vision-language model to enhance your prompt before the video generation begins.
Simply load a reference image and write a basic description of what you want to happen. The enhancer analyzes both your image and instructions, then converts them into a detailed prompt structured specifically for MiniMax H3.
It can improve the description of:
Characters and visual elements
Actions and sequence of events
Camera movement and framing
Environment, lighting, and atmosphere
Visual continuity and details that should be preserved
Dialogue in the original language
Ambient sounds, sound effects, and music
The enhanced prompt is automatically sent to MiniMax H3. It is also displayed inside the workflow, allowing you to check exactly what H3 will receive.
In my tests, the resulting videos followed the original instructions much more accurately, especially in scenes involving specific actions, character interactions, camera movements, and dialogue.
The workflow includes a switch to enable or disable the Prompt Enhancer. This allows you to use either the enhanced prompt or your original text without changing any connections.

The first run may take longer while the vision-language model is loaded. Generating the enhanced prompt also adds some processing time, but in my tests, the improvement in prompt accuracy and instruction following was absolutely worth it.
The original workflow was preserved, while the enhancer was added as an optional and fully integrated stage.
