For video-to-video generation, given an input video with N frames I = {I1, . . . , IN } and a text prompt Ļ , the goal is transfer it to a new video I ā² = {I ā² 1 , . . . , Iā² N } which adheres to the provided prompt Ļ ā² , while keeping consistency across frame. We first discuss how we inflate the image-to-image diffusion model, such as ControlNet to video, with spatialtemporal attention [6, 25, 35, 46] (Section 4.1) Then, we introduce how to incorporate imperfect optical flow as a condition into our model (Section 4.2). Lastly, we introduce the edit-propagate design for generation (Section 4.3).
