Latent Diffusion
In short: Latent diffusion is a generative AI technique that performs the diffusion process in a compressed latent space rather than pixel space, enabling efficient high-quality generation for lip sync.
About Latent Diffusion
Latent diffusion models apply the iterative denoising process of diffusion models in a lower-dimensional latent space encoded by a variational autoencoder, rather than operating directly on high-resolution pixel data. This dramatically reduces computational cost while maintaining generation quality, making diffusion-based approaches practical for video applications like lip sync.
By working in latent space, these models can generate high-resolution lip sync output with fine-grained detail while keeping inference time manageable. The LatentSync model and Sync's latest architectures leverage latent diffusion techniques to achieve state-of-the-art visual quality at production-viable speeds.
How Latent Diffusion Connects to Lip Sync
Latent Diffusion relates to several other concepts in the AI lip sync pipeline: Diffusion Models , and Latent Space .
