Stand-In Official Preprocessor ComfyUI Nodes

<h1> <img src="Stand-In.png" width="85" alt="Logo" valign="middle"> Stand-In </h1>

🧩 Only images processed with this official preprocessor can fully unleash the power of Stand-In.

---

This repository provides a temporary ComfyUI node implementation of the Stand-In preprocessor, aiming to correct the misunderstanding of Stand-In’s preprocessing logic in ComfyUI-WanVideoWrapper.

We strongly recommend using the workflows provided in this repo to ensure proper compatibility and the best identity-preserving performance.

Note: This is a temporary node. Features such as KV cache support and advanced attention mechanisms are not yet implemented. We are actively developing the official full-featured ComfyUI nodes for Stand-In.

⚠️ Important Usage Tips

Prompt Writing Tip:
If you do not wish to alter the subject's facial features, simply use "a man" or "a woman" without adding extra descriptions of their appearance.
Prompts support both Chinese and English input.
The prompt is intended for generating frontal, medium-to-close-up videos.

Input Image Recommendation:
For best results, use a high-resolution frontal face image.
There are no restrictions on resolution or file extension, as our built-in preprocessing pipeline will handle them automatically.

We are also actively developing a more flexible version of Stand-In.
