Efficient Camera-Controlled Video Generation of Static Scenes via Sparse Diffusion and 3D Rendering
Jieying Chen, Jeffrey Hu, Joan Lasenby +1 more
Modern video generative models based on diffusion models can produce very realistic clips, but they are computationally inefficient, often requiring minutes of GPU time for just a few seconds of video. This inefficiency poses a critical barrier to deploying generative video in applications that requ...
