Introducing VSTAR for improved video synthesis dynamics.
תקציר
The content introduces VSTAR, a method for Generative Temporal Nursing (GTN) to enhance video synthesis dynamics. It addresses limitations in open-sourced text-to-video models by proposing Video Synopsis Prompting (VSP) and Temporal Attention Regularization (TAR). Experimental results demonstrate the superiority of VSTAR in generating longer, visually appealing videos with dynamic content. The analysis highlights the importance of temporal attention in video synthesis and offers insights for future T2V model training.

סטטיסטיקה
Despite tremendous progress in the field of text-to-video (T2V) synthesis, open-sourced T2V diffusion models struggle to generate longer videos with dynamically varying content.
Proposed method VSTAR showcases superiority in generating longer, visually appealing videos over existing open-sourced T2V models.
