WAN-L.O.V.E. Low VRAM Image-to-Video Fast All-In-One

WAN-L.O.V.E. is hybrid Wan Low Overhead VRAM Efficiency Image-to-Video Fast (4-step) All-In-One model (full checkpoint: UNET, CLIP and VAE). All you need to encode source images is this model and, optionally, CLIP Vision model for Wan. Use CFG 1 and Euler sampler and beta scheduler and model shift 8-12. Enjoy!

In ComfyUI just use usual default workflow with checkpoint loader, CLIP vision loader and sampler.

Note: If you look for Wan 2.2 14B all-in-one version, then try this checkpoint, the same 1-pass workflow as for Wan 2.1 will work pretty well.
