Product Information
Key Features of Video Latent Diffusion Models - High-Resolution Video Synthesis
Video LDMs map videos into a compressed latent space and model sequences of latent variables corresponding to the video frames. They initialize the models from image LDMs and insert temporal layers into the LDMs' denoising neural networks to temporally model encoded video frame sequences.
Temporal Video Generation
Video LDMs generate temporally coherent videos by modeling sequences of latent variables corresponding to the video frames.
High-Resolution Video Synthesis
Video LDMs can generate high-resolution videos by leveraging spatial diffusion model upsamplers and temporally aligning them for video upsampling.
Personalized Video Generation
Video LDMs can generate personalized videos by inserting the temporal layers that were trained for our Video LDM for text-to-video synthesis into image LDM backbones that we previously fine-tuned on a set of images following DreamBooth.
Long Video Generation
Video LDMs can generate long videos by applying our learnt temporal layers convolutionally in time.
Simulation of In-the-Wild Driving Data
Video LDMs can simulate in-the-wild driving data by training a bounding box-conditioned image-only LDM and leveraging this model to place bounding boxes to construct a setting of interest.
