NVIDIA VideoLDM

What is NVIDIA VideoLDM?

Video Latent Diffusion Models (Video LDMs) are designed for high-resolution video generation with computational efficiency. These models leverage the Latent Diffusion Model (LDM) paradigm by mapping videos into a compressed latent space and modeling sequences of latent variables corresponding to video frames. By extending pre-trained image LDMs to include temporal layers based on temporal attention and 3D convolutions, Video LDMs can generate temporally coherent videos. The process involves generating sparse keyframes initially, which are then upsampled temporally to create high-quality videos. Video LDMs have been applied in diverse areas such as in-the-wild driving scene video synthesis and creative content creation with text-to-video modeling, demonstrating state-of-the-art performance in generating long, high-resolution videos and enabling personalized text-to-video generation.

Who created NVIDIA VideoLDM?

VideoLDM was created by Andreas Blattmann, Robin Rombach, Huan Ling, Tim Dockhorn, Seung Wook Kim, Sanja Fidler, and Karsten Kreis. The project was conducted during internships at NVIDIA . The VideoLDM project focused on high-resolution video synthesis using Latent Diffusion Models (LDMs), demonstrating applications in driving video synthesis and text-to-video generation .
