Details of the low-quality mode:
1. lower resolution, video resized as long-side 512 and keep aspect ratio.
2. subgraph instead of full-graph, causing noticeable "frame jumps".
3. only use the first 8s of your input audio.
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.
5. use open-source tools like SMPLerX-s-model, Wav2Lip, and FiLM for faster processing.
