wan2.2-14b-i2v-city-the-animation

A Wan 2.2 14B i2v LoRA for emulating the City the Animation movement style.

Note:

• I expected the training run to produce a high and a low noise .safetensors, but it did not, so I tried it as just the high-noise LoRA, and it worked fine that way.
• The dataset focuses on action scenes
• the dataset was captioned by a custom-written video captioning tool

Trained using musubi-trainer with the following settings for Wan 2.2 i2v

using a dataset consisting of 101 640x360 15-second videos plus annotations. The LoRA took 5.5 days using a 4090D 48GB GPU. I wanted to train at 836x480 but it would always OOM before completing an epoch, so I scaled the video down to 640x360, which is still a common SD resolution.
