### 🔑 Quick Inference

python infer.py

> Tips
> - Audio CFG: Audio CFG works optimally between 2~3. Increase the audio CFG value for better lip synchronization, while decreasing the audio CFG value can improve the visual quality.
> - Text CFG: Text CFG works optimally between 4~6. Increase the text CFG value for better prompt following, while decreasing the text CFG value can improve the visual quality.
> - TeaCache: The optimal range for `--teacache_thresh` is between 0~0.1.
> - Sampling steps: 5 steps for talking head, 15~25 steps for talking body. 
> - ​Long video generation: If you want to generate a video longer than 138 frames, you can use Long Video CFG.
