Motion Brush User Guide V1
Motion Brush Feature: By uploading an image, users can designate an area or element within the image using either "automatic selection" or "manual brushing" and add a motion trajectory. Users then input the desired motion prompt (element + motion). After clicking "Generate", the model will create a video based on the specified motion. This allows users to control the motion of specific elements and make the image-to-video generation more advanced and controllable.
The Motion Brush Feature, with its advanced controllability in image-to-video generation, allows users to specify the desired motion for certain areas or elements. For example, it can generate complex motions like "ball games", handle the movement and changes in direction of people/animals and supports simultaneous settings for up to six elements and their trajectories. Additionally, the "Static Brush" feature enables users to designate static areas by brushing and fix pixels in the brushed areas, preventing camera movement. If users want to avoid camera movements caused by the motion trajectory, it is recommended to add a static brush at the bottom of the image.
●Tips you definitely wanna know！
○When using the Motion Brush feature, be sure to add a text prompt that matches the movement of the area/element. For example, use prompts like "a puppy running on the road" following the "element + motion" format.
