Today, I experienced the website of Wonder Dynamics and mainly tried out two features: Live Action and AI Mocap.
I compared the original video with the modified one:
First, I tried the Live Action feature. During the process, I followed these steps:
Upload the video. The system automatically selects characters. It provides some preset character models for selection. If you wish, you can also generate your own characters, but this process might be a bit complicated. In this trial, I chose the system's default character model. Drag the selected character onto the task you want to replace. Click execute, and then you can patiently wait for the result.
Next, I experienced the AI Mocap feature. The usage process of this feature is similar to Live Action, but it can generate FBX files (universal 3D model files). This means that you can directly modify the source file to change the character's actions.
