Video editing is a challenging task that requires manipulating videos on boththe spatial and temporal dimensions. Existing methods for video editing mainlyfocus on changing the appearance or style of the objects in the video, whilekeeping their structures unchanged. However, there is no existing method thatallows users to interactively ``drag'' any points of instances on the firstframe to precisely reach the target points with other frames consistentlydeformed. In this paper, we propose a new diffusion-based method forinteractive point-based video manipulation, called Drag-A-Video. Our methodallows users to click pairs of handle points and target points as well as maskson the first frame of an input video. Then, our method transforms the inputsinto point sets and propagates these sets across frames. To precisely modifythe contents of the video, we employ a new video-level motion supervision toupdate the features of the video and introduce the latent offsets to achievethis update at multiple denoising timesteps. We propose a temporal-consistentpoint tracking module to coordinate the movement of the points in the handlepoint sets. We demonstrate the effectiveness and flexibility of our method onvarious videos. The website of our work is available here:https://drag-a-video.github.io/.
