• Abstract summary: We train a video generation model conditioned on sparse or dense video trajectories. We translate high-level user requests into detailed, semi-dense motion prompts. We demonstrate our approach through various applications, including camera and object motion control, "interacting" with an image, motion transfer, and image editing.

• Abstract: Motion control is crucial for generating expressive and compelling video content; however, most existing video generation models rely mainly on text prompts for control, which struggle to capture the nuances of dynamic actions and temporal compositions. To this end, we train a video generation model conditioned on spatio-temporally sparse or dense motion trajectories. In contrast to prior motion conditioning work, this flexible representation can encode any number of trajectories, object-specific or global scene motion, and temporally sparse motion; due to its flexibility we refer to this conditioning as motion prompts. While users may directly specify sparse trajectories, we also show how to translate high-level user requests into detailed, semi-dense motion prompts, a process we term motion prompt expansion. We demonstrate the versatility of our approach through various applications, including camera and object motion control, "interacting" with an image, motion transfer, and image editing. Our results showcase emergent behaviors, such as realistic physics, suggesting the potential of motion prompts for probing video models and interacting with future generative world models. Finally, we evaluate quantitatively, conduct a human study, and demonstrate strong performance. Video results are available on our webpage: https://motion-prompting.github.io/

  Current video generation models often entangle object movement with camera motion and other scene changes. We introduce Motion Modes, a training-free approach that explores a pre-trained image-to-video generator's latent distribution. We achieve this by employing a flow generator guided by energy functions designed to disentangle object and camera motion.

  We propose a pre-trained image-to-video model to disentangle appearance from motion. Our method, called motion-textual inversion, leverages our observation that image-to-video models extract appearance mainly from the (latent) image input. By operating on an inflated motion-text embedding containing multiple text/image embedding tokens per frame, we achieve a high temporal motion granularity. Our approach does not require spatial alignment between the motion reference video and target image, generalizes across various domains, and can be applied to various tasks.
