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
