wan-disney-DCM-distilled

This is a standard PEFT LoRA derived from Wan-AI/Wan2.1-T2V-1.3B-Diffusers.

The main validation prompt used during training was:

A black and white animated scene unfolds featuring a distressed upright cow with prominent horns and expressive eyes, suspended by its legs from a hook on a static background wall. A smaller Mickey Mouse-like character enters, standing near a wooden bench, initiating interaction between the two. The cow's posture changes as it leans, stretches, and falls, while the mouse watches with a concerned expression, its face a mixture of curiosity and worry, in a world devoid of color.

Validation settings

• CFG: 1.0
• CFG Rescale: 0.0
• Steps: 8
• Sampler: FlowMatchEulerDiscreteScheduler
• Seed: 42
• Resolution: 832x480

Note: The validation settings are not necessarily the same as the training settings.

## Optional: quantise the model to save on vram.
## Note: The model was quantised during training, and so it is recommended to do the same during inference time.
