​
Overview

This schema is used for fine-tuning models with image to video capabilities.

​
Schema Type

When creating a fine-tune with this schema, use: 
{
  "resource": "main/your-dataset.parquet",
  "base_model": "<model-canonical-name>",
  "script_type": "image_to_video",
  "training_params": {
    ...
  }
}
Key Parameters:
  • script_type: image_to_video (the fine-tune type)
  • base_model: One of the supported model canonical names below

​
Supported Models

  • Wan2.1 1.3B - Text to Video (Wan-AI/Wan2.1-T2V-1.3B-Diffusers)
  • Wan2.2 A14B - Text to Video (Wan-AI/Wan2.2-T2V-A14B-Diffusers)
  • Wan2.1 14B - Text to Video (Wan-AI/Wan2.1-T2V-14B-Diffusers)
