First, open the software and find the "Tracker" function module. Click to enter and select the "Stable Motion" mode in the function options. At this point, two frames for positioning will appear in the preview window on the interface. This step is crucial for achieving accurate tracking results later. We must choose a stable tracking point that will not disappear from the screen throughout the process. Taking the current picture as an example, it is recommended to choose the nose of the person as the tracking point: compared to the eyes, the nose is more stable in the picture and can effectively avoid tracking interruption caused by the tracking point leaving the screen.

After selecting the tracking point, click the "Forward Analysis" button on the interface. After the analysis is completed, click the "Apply" button. In the pop-up settings window, make sure to check both the "X-axis" and "Y-axis" options. With this setting, the software can accurately capture and track the movement of the character's head, whether it rotates left and right (X-axis direction) or moves up and down (Y-axis direction).

However, many users often encounter a common issue when operating: black borders suddenly appear at the top, bottom, left or right edges of the screen. So, what should we do? Method one: Use the "Zoom" tool to appropriately enlarge the material, and cover the black borders by expanding the display range of the material. Method two: In the software's "Effects panel", find the "Dynamic Tiling" effect, add it to the current material; then in the effect settings, adjust both the "Output Width" and "Output Height" to 200, and check the "Mirror Edges" option.
