This is a suite of nodes which was inspired by ComfyUI--WanImageToVideoTiled and brings VAE tiling functionality to WAN conditioners not (yet) supported by ComfyUI--WanImageToVideoTiled. The nodes function identically to their original counterparts with the exception of VAE tiling. By tiling the conditioners' VAE encoding, additional frames and/or larger frame sizes can be squeezed from your VRAM with zero impact on the quality and only negligable impact on generation time. This is especially useful in low-VRAM setups, where the conditioner can oftentimes be a bottle neck.
