This is a custom ComfyUI node (not official) built by aistudynow.com to run Tencent’s HunyuanVideo Foley model inside ComfyUI. It takes a silent video and generates sound that matches the picture — ocean waves, fire crackle, thunder, footsteps, even subtle music when the scene calls for it.

Setup is simple: clone the repo, drop the model weights, point the four paths, and run. Once configured, you can add natural sound to any quiet clip without manual audio editing.
