<b>Official Gradio demo</b> for <a href='https://github.com/TencentARC/MotionCtrl' target='_blank'><b>MotionCtrl: A Unified and Flexible Motion Controller for Video Generation</b></a>.<br>
🔥 MotionCtrl is capable of independently and flexibly controling the camera motion and object motion of a generated video, with only a unified model.<br>
🤗 Try to control the motion of the generated videos yourself!<br>
❗❗❗ This demo provides model of **MotionCtrl** deployed on **LVDM/VideoCrafter** and **VideoCrafte2**. 
Deployments in **LVDM/VideoCrafter** include both Camera and Object Motion Control, 
while deployments in **VideoCrafte2** only include Camera Motion Control.
