# Wan2.1-I2V-1.3B-InP Crush-Smol Example
These are e2e example scripts for finetuning Wan2.1 T2V 1.3B InP on the crush-smol dataset.
## Execute the following commands from `FastVideo/` to run training:
### Download crush-smol dataset:
`bash examples/training/finetune/wan_i2v_14b_480p/crush_smol/download_dataset.sh`
### Preprocess the videos and captions into latents:
`bash examples/training/finetune/wan_i2v_14b_480p/crush_smol/preprocess_wan_data_i2v.sh`
### Edit the following file and run finetuning:
`bash examples/training/finetune/wan_i2v_14b_480p/crush_smol/finetune_i2v.sh`
