How does AE make 3d tracking camera and how to use it?

AE's prompt "3D camera tracker: the layer size must be consistent with the composition, use the default change value" when creating a 3D tracking camera is caused by an error when creating a 3D camera.

The solution is:

1. Click to select the green tracking point, hold down Shift, add and select as many green tracking points as possible, and the green tracking points are relatively stable.

2. In order to make the tracking surface more stable, we add as many tracking points as possible and click the tracking surface with the right mouse button.

3. Select "Create Solid Foundation and Camera" from the right-click menu.

4. Click to select the tracking entity layer, and press the rotation shortcut key R. ..

5. Adjust the parameters of the lower Z axis so that the solid bottom surface is parallel to the desktop.

6. Hold down the green coordinate axis and adjust the position of the bottom tracking surface until you are satisfied.

7. In this way, we created a 3d tracking camera in AE.
