Details of the low-quality mode:
<br>
1. lower resolution, video resized as long-side 512 and keep aspect ratio.
<br>
2. subgraph instead of full-graph, causing noticeable "frame jumps".
<br>
3. only use the first 8s of your input audio.
<br>
4. only use the first 20s of your input video for custom character. if you custom character, it will only generate one video result without "smoothing" for saving time.
<br>
5. use open-source tools like SMPLerX-s-model, Wav2Lip, and FiLM for faster processing.
