- ⭐️ step1: Upload or select one image from Example.
- ⭐️ step2: Click 'Add Drag' to draw some drags.
- ⭐️ step3: Input text prompt that complements the image (Necessary).
- ⭐️ step4: Select 'Drag Mode' to specify the control of camera transition or object movement.
- ⭐️ step5: Click 'Run' button to generate video assets.
- ⭐️ others: Click 'Delete last drag' to delete the whole lastest path. Click 'Delete last step' to delete the lastest clicked control point.
