Plain Language Accessible to non-experts
Imagine you're directing a movie with a toy dog you want to animate in a video. MotionBooth acts like a smart director, needing only a few photos of the toy dog to bring it to life in the video. It not only animates the toy dog but also controls the camera's movement, much like a director adjusting camera angles during filming. This process doesn't require complex training, just like you don't need daily practice to shoot a good video.

Abstract
In this work, we present MotionBooth, an innovative framework designed for animating customized subjects with precise control over both object and camera movements. By leveraging a few images of a specific object, we efficiently fine-tune a text-to-video model to capture the object's shape and attributes accurately. Our approach presents subject region loss and video preservation loss to enhance the subject's learning performance, along with a subject token cross-attention loss to integrate the customized subject with motion control signals. Additionally, we propose training-free techniques for managing subject and camera motions during inference. In particular, we utilize cross-attention map manipulation to govern subject motion and introduce a novel latent shift module for camera movement control as well. MotionBooth excels in preserving the appearance of subjects while simultaneously controlling the motions in generated videos. Extensive quantitative and qualitative evaluations demonstrate the superiority and effectiveness of our method. Our project page is at https://jianzongwu.github.io/projects/motionbooth
