## Overview

This repository combines Wan video-generation capabilities with Kokoro speech synthesis and audio-analysis utilities; the visible product workflow is InfiniteTalk generation from prompts and media inputs to a rendered video. Wan also exposes text-to-video, image-to-video, first/last-frame, and VACE generation paths. The source index supports the module relationships below, but excerpts are incomplete and the README is empty, so some internal orchestration details are omitted.

Main entry points: [`wan/multitalk.py`](https://github.com/dr-rehansaeed/infinite-talk/blob/main/wan/multitalk.py) (InfiniteTalk pipeline), [`wan/image2video.py`](https://github.com/dr-rehansaeed/infinite-talk/blob/main/wan/image2video.py) (Image-to-video), [`wan/first_last_frame2video.py`](https://github.com/dr-rehansaeed/infinite-talk/blob/main/wan/first_last_frame2video.py) (First/last-frame video), [`wan/text2video.py`](https://github.com/dr-rehansaeed/infinite-talk/blob/main/wan/text2video.py) (Text-to-video)
