Diff2Lip: what it does well
- Inference scripts support audio-video pairs and single videos.
- Cross and reconstruction inference modes are documented.
- A Google Colab notebook is linked for trying the project.
- Inference can run distributed generation with more than one GPU.
- The license permits sharing and adaptation with attribution for noncommercial purposes.
What to know first
- The project is not real time yet.
- Commercial use is barred by its CC BY-NC 4.0 license.
- Setup instructions require Python 3.9 and FFmpeg 5.0.1.
LatentSync: what it does well
- Free open-source release includes inference code and checkpoints.
- Offers both Gradio and command-line inference.
- Includes data processing and training code.
- Version 1.5 minimum inference requirement is 8 GB VRAM.
What to know first
- Version 1.6 requires at least 18 GB VRAM for inference.
- U-Net training configurations require 20–55 GB VRAM.
- More inference steps slow generation.
- Higher guidance scale may cause distortion or jitter.
