Nodes for loading and using VAEs in ways not supported by base ComfyUI. Currently supports Wan upscale VAE, more may be added later as needed.
cd custom_nodes
git clone https://github.com/spacepxl/ComfyUI-VAE-Utils
That's it! No extra requirements outside of what ComfyUI already uses.
Wan2.1 VAE 2x imageonly real v1
Direct replacement for native Load VAE node, but with added input/output channel detection for Wan2.1 VAE
Decode latents with optional auto detected upscaling, and optional tiling
Simple neural latent upscaler (right), far from optimal but much better than naive bilinear/bislerp interpolation (left).
Currently supported: Wan2.1 2x

To use native VAE decoding with latents from kijai/ComfyUI-WanVideoWrapper, you need to un-normalize the latents first using this node:
