Now faster and easier to install

This workflow uses a small baseline generation using the 14B image to video model, followed by upscaling, and then smoothing out the result using the 5B model.

This lets you test prompts and iterate quicker on the base generation before upscaling to a final resolution.

Links for all the required models and where to put them are now included in the workflow.

FAQ

Do I need both Wan 2.1 and 2.2 VAEs?
Yes. The 2.2 VAE only works with the 5b model (confusing, I know). Make sure the main section loads the 2.1 VAE, and the upscale section loads the 2.2 VAE.

Its frozen on VAE decode

The second vae decode can take a long time. Just be patient.
