Creating a Bezier Path at Z axis

Hi,

I am new to Motion and have been facing some issues. I have a birds-eye view image of a project with some buildings. I plan to run a streak of light on the building outline to highlight individual buildings with background VO with the camera zooming in slowly. When I use the bezier tool to draw the outlines, all seems good unless the camera zoom in. The issue is with the camera zoom the, outline loses its place. When I checked the same from the top view, I saw that the image plane and the bezier point are not on the same plane and I am unable to start the beizer tool as same as the image plane.

How do I start to draw the bezier on the same point of the image on the Z axis? Am I missing something?

thanks

If you're trying to trace a building on a 2D video, then you're really overthinking this.

All you need to do is trace the shapes on the video in 2D. Add a camera and animate. Do the tracing before you even add a camera. Both the video and the bezier are in the same 2D space inside a group (which will turn to 3D when the camera is added). The camera is outside that group, so everything inside the group maintains their relationships to each other.

I haven't actually tried it, but I think that you may have answered your own question: switch to the top camera and create or adjust the Bezier curve.

Yes that was the first resort I tried. But I would need the front angle to be able to trace the edges of the buildings .Won’t be able to do that from top angle .

Yes ! I would have to do the tracing before I add the cameras . I added the camera before the tracing which led to this issue . This is helpful. Thanks !
